From the following list of frameworks, which one would you use to develop a rich web application and why would you choose it over the others?
Sproutcore
GWT
ExtJS
GXT
SmartGWT
Dojo / Dijit
Flex
Capuccino
Grails
I'm personally tired of browser inconsistencies. If someone else has solved the problem, I'd rather not do it again. That's why I'm getting more interested in front ends like cappuccino and qooxdoo. They are a zero-HTML zero-CSS solution.
These are based on my personal experiences using the frameworks you have mentioned. So yes, it is a bit biased. So as others have said over and over again, define your requirements and which one do you think fits your requirement based on what people have suggested here.
GWT is too verbose eventhough I found many Java developers love GWT because you can unit test it and it's all in Java. But I personally don't like it because it is far from being simple. There are times when I feel I can tweak a little bit with Javascript, but with GWT I am enforced to do it with several lines of Java code.
GXT is too far from GWT these days and you will find it difficult to do things as GXT has its own way of doing things which is way too different from GWT. When complex requirement come up, in the end you are going to go back doing plain GWT. And oh, their technical support is not that good either as I had several bad experiences when asking few questions to them.
Ext-JS is good for simple stuff and the look and feel is really slick. But when things gets more complex, you are going to fight you're way through. Eventhough I have dealt with the GXT tech support, I haven't dealt with the ExtJS tech support since they have different people eventhough it's in one company, so I can't say much.
Flex is nice, really nice. But again it is good for simple stuff. Once things gets more complicated you are going to write lots of actionscript, which is less enjoyable. There are many things that is available out of the box which may be to difficult if you have to code it in Javascript, like multimedia support. And oh, if you are writing for a public website you must consider that not too many user has flash plugin on their browser.
Grails, I'm not sure how you would implement RIA apps with Grails since Grails is just another MVC framework which you need to add your own RIA framework on top of it such as the ones that you have mentioned.
This is strictly a matter of opinion. You will not get any definitive answers from anyone, since anyone that answers will have one or another that they personally prefer.
Try each one for long enough to decide which one is best for your (or your team's) purposes.
That being said, I prefer GWT. Others will invariably disagree with me.
Reasons that I like GWT:
You can share (some) client- and server-side code (as long as your server is written in Java)
GWT makes a lot of advanced performance features really easy (e.g., deferred JS loading, image spriting, CSS obfuscation)
A focus on one-page apps, with third-party support for Places (using the gwt-presenter library)
It's just as easy to add GWT to an existing web page as it is to create a full one-page GWT app
UiBinder allows you to write your UI using a declarative HTML-like syntax; you're not stuck writing Swing-like UI if you don't want to
Browser incompatibilities are (mostly) taken care of by GWT -- you just write Java code, and GWT compiles it to work on every browser
Things that may make GWT not right for you:
If your server is already written in something besides Java, you will still be able to write your UI in GWT, but you'll lose out on some nice features
Compilation time using GWT is a non-trivial cost -- Development Mode mitigates this a lot, but it's still an issue sometimes
As others have mentioned, GWT can be considered "verbose" compared to simple JavaScript libraries like jQuery or ExtJS
Ext GWT has worked well for my project. The premium support has been good.
However the project is for internal use which has allowed deployment to be restricted to one browser on one OS, and no effort has been made to change the default appearance or behaviour of Ext GWT.
Developing entirely within Java is a key benefit as it helps to keep the project manageable as features are added.
I am currently working on a grail/flex hybrid app that is working a lot better than I expected. I have looked at GWT but there were not a lot of books about it at the time and it seemed to stress the leveraging of Swing-like programming techniques which I have never liked. I agree with the comment about trying them all out. Run hello app they all have and measure how hard or easy it is to modify. Also tool (IDEs, Maven, CI...etc) support can be a big factor as well in terms of being immediately productive.
We are using Grails+ExtJS here. Since we try to make an idiomatic ExtJS application, Grails is not fully utilized, though it still makes sense to use Grails instead of, say, JSP, for the server-side part.
Why ExtJS: Because it's a very rich toolkit for GUI-like web applications. Our job is to replace an old Motif GUI, so this is exactly what we need.
Why Grails: Because it gets the job done easily and quickly. For the communication with the ExtJS part, we need a lot of JSON, and in Grails it's like that:
import foo.bar.FooBar
class FooBarController {
def viewFooBars = {
def list = FooBar.getList(session.userId, params.foo, params.bar)
def result = [resultset: list] as JSON
response.setHeader('Content-disposition', 'filename="json"')
response.contentType = "text/json";
render result
}
}
And that's even two or three lines more than necessary...
Unfortunately the answer will be opinionated, GWT in it's purest form is not an eye-candy. That being said, ExtJs GXT is super hunky dory. One of the major issues I face with evolving frameworks is that they are not absolutely defect free, If I remember correctly, GWT 2.0 was shipped out with missing CSS styles for some of the new layouts. I am trying to trouble shoot an issue in ExtJs/GXT since last 5 days :(, frameworks obfuscate a lot of things. I will go with any framework that is absolutely robust and gives appropriate error messages. I haven't worked with others though.
I'd recommend Dojo.
In addition to the massive infrastructure it provides, Dojo 1.6 is also the first (and only) popular JavaScript Library that can be successfully used with the Closure Compiler's Advanced mode, with all the size, performance and obfuscation benefits attached to it -- other than Google's own Closure Library, that is.
http://dojo-toolkit.33424.n3.nabble.com/file/n2636749/Using_the_Dojo_Toolkit_with_the_Closure_Compiler.pdf?by-user=t
In other words, a program using Dojo can be 100% obfuscated -- even the library itself.
Compiled code has exactly the same behavior as plain-text code, except that it is much smaller (average 25% over minifiers), runs much faster (especially on mobile devices), and almost impossible to reverse-engineer, even after passing through a beautifier, because the entire code base (including the library) is obfuscated.
Code that is only "minified" (e.g. YUI compressor, Uglify) can be easily reverse-engineered after passing through a beautifier.
ExtJs is great for creating complex web applications. The API provides anything you can imagine in a webapp and its really easy to extend any component after some time.
You can plug it to any backend (we use django or php) and reuse or extend any component in several different applications.
You'll need severals months to feel comfortable with it. IMHO.
That said, the lib is sometimes a bit too slow for simples uis like a website (then you can use ExtCore). But when it comes to webapps this is not an issue.
Im not a java guy so GWT was not an option for me :/
hope this helps

I have been developing a plain JSP/Servlet web application, which focuses mainly in collecting large sets of data through JSPs, processing them and finally commiting them to a MySQL database. Imagine something like a declaration of assets for a pretty big number of people.
While it works pretty good now, the code is really jumbled up and since I now have the time, I am thinking of completely redesigning the whole application in a more sophisticated and reusable way. My main problem is that forms are built mainly through jQuery (my form_build.js and form_validate.js files span over 600 lines each at the moment), and the back-end java code is jumbled up since there is massive use of name[counter] input fields.
I.e. The user can add 5 assets in the form, where he has to submit something like 30 fields of information on each one. The form sends them in the form of attribute[asset_counter].
If I managed to make myself clear, I have been looking into the Google web toolkit - which I had no idea of before - and from what I gather mastering it will take some time for me. Is it worth the trouble, or is it aimed at something completely different? And is there a framework or technique that can handle efficiently what I need?
Frankly, I am a senior java developer and I used a lot of jsp/jsf web applications accompanied by EJB, webservice, simple spring web apps, and I recently came up to use GWT.
It's a very nice platform, it has the following advantages:
All the code is compiled to html/JS which is better in terms speed
and browser understanding agilty
It uses built in JSON xml transer (nice approach)
It use built in AJAX (nice approach)
It use it's own cleint server platform (no need to use other
libraries for each one)
It will adopt to any browser (strong competetor)
drowbacks:
Sometimes it takes time to load in the browser (specially when using
FlexTables)
I advise you to use it!
GWT is a very powerful toolkit, and from what I understand it might help you to better organize you client side code. But you also have to consider some high-level JS framework like backbone.js+require.js or Google Closure. Time spent to learn this frameworks this bascially the same as for GWT, the choice basically depends on what your team prefer, JS or Java. In most cases when logic on client side gets very complicated, I will choose GWT.
I am looking to build a GWT based web application. Being new to GWT, am looking for suites that provide the best GWT widgets (in terms of user experience, variety, styles, etc.), to help build a web app.
I have come across SmartGWT, but looking for other options/suggestions.
Thanks in advance!
I've done apps in both GWT and SmartGWT. My observations, for what it's worth:
SmartGWT has all sorts of cool features, out of the box. It's easy to be seduced by the SmartGWT showcase.
GWT is converging on SmartGWT, and quickly. For instance, the new DataGrid
can stand up against the SmartGWT ListGrid and come away looking good.
In order for GWT to look good though, there has to be real skill in the
developer. SmartGWT can make anyone look good, it seems, but to make
GWT shine takes skill.
Once you have that level of skill, though, there's no looking back.
GWT seems to me to be much more flexible, a consequence of the building-block approach. SmartGWT is more monolithic.
SmartGWT's design has some portability issues. I successfully took a pure GWT app I made and re-worked it (minimal effort) to run nicely in a BlackBerry PlayBook browser. I took a
SmartGWT app I had made at about the same time, and half the widgets
didn't work.
For an enterprise level solution I'm working on, I'm using pure GWT and I don't regret having made that choice.
I would suggest using standard gwt widgets. Simply because,
1)they are best documented,
2)they are highly customizable via css
3)from what I observe they provide the best performance
4)you dont need to learn a whole new framework built on top of another framework
but if you insist on using a framework then I suggest you take a look at this question
My advice to you is to consider your needs. Plain GWT and SmartGWT both are the best supported, so you need not look for more (unless of course both fail in what you want).
Go to their respective showcases and see what they offer and how it fits your requirements.
If gwt satisfies all your UI requirements, my advice is to choose it over SmartGWT. gwt beats SmartGWT in learning curve and documentation anytime. Also its faster(my opinion). If gwt doesn't satisfy your needs and SmartGWT does, then you should consider making the switch.
I have a year experience in smartGWT, when we started our first gwt lessons, they said use the basic gwt features and build own framework otherwise we can encounter errors which may lead to dead-ends. We considered the idea, but for the project (since we already had deadline) decided to look after some extension of gwt. We found smartGWT. The showcase was really convincing. Remember these are widgets, the basic logic of your system is still up to you.
In case if you start using smartGWT: If you don't use JSON but some normal list of java structures prepare to get hard hours/days to get use to datasources, grids, and few other components. Seriously, it had ridiculous problems (for example switching two configuration code line without reason makes work the listgrid), BUT before you drop the entire idea to use it, after a while it starts to work, and it becomes really impressive and comfortable. This is a kind of work "make it once, will work hundreds of times".
In my opinion:
don't start use smartGWT if you want to make a system which is not too complicated.
start use it if you need complicated system with lot of different features, if you don't have the time to develop everything for yourself: many components are ready in smartGWT.

Closed 9 years ago.
My company is planning on developing a brand new web front-end application.
Some background:
It must "sizzle" i.e. a nice marketable look and feel.
Our development team has no Java experience, with limited experience in Silverlight, Javascript, JQuery or CSS.
Time to market is a factor.
We need to stream large amounts of data from an Oracle database.
It must support 500 - 1000 concurrent users
It will be hosted internally behind a firewall.
We need mapping (geo-spatial) capabilities.
Someone has recommended using GWT instead of Silverlight or Traditional technologies(Javascript, jquery, CSS etc.).
I am not sure if this is the right way to go? A lot of the GWT news is from 2007/2008. It makes me think that this technology is old and maybe dying.
If you had a choice would you choose GWT?
unfortunately two of your statements are mutually exclusive in this context:
Our development team has no Java experience
Time to market is a factor
I'm a Java programmer who has picked up GWT over the last year or so. It's immensely effective being able to write direct to the browser using a compiled language & mature development tools. I can fly through web-development faster than ever before (using ASP, JSP, ExtJS ...).
But, as the other commenters have said: if you've no Java experience you're going to find it a real challenge picking up both technologies (Java & GWT) in a short time. If you do manage to make it to market in a reasonable time I could only imagine the code base would be in very poor condition (since you'd be learning as you go) - which would be a very poor foundation for your organisation's shiny new venture.
There again, you don't have a 'lot' of skills in the other related skills you listed either.
I suspect there's a more effective solution. As some wise old goat project manager said:
I have three variables to delivering your project: time, cost and quality. Pick any two
In your situation, if the organisation wants a quality product in a short time, it's the cost factor that must compensate - your organisation should buy in some interim GWT expertise to give you a sound software architecture and to mentor your team for the next few months. After that you'll be ready to take the reigns, inheriting a quality codebase by 'standing on the shoulders of giants'.
As others have said, GWT definitely is not a dying project. Quite the contrary actually as there are now more than 20 regular contributors from within Google (versus a semi-dozen back in 2008). Wave (despite being discontinued as a Google service, it's still alive as an Apache Foundation project), Orkut, AdWords, Google Moderator and the new (still beta) Google Groups are made with GWT; and parts of Google Buzz and a few other projects at Google are built with it too.
Now as to your choice:
Silverlight is a dying technology. Microsoft made it clear that it now invests in "HTML5": http://www.zdnet.com/blog/microsoft/microsoft-our-strategy-with-silverlight-has-shifted/7834
GWT is mostly a client-side toolkit, but it comes with "high productivity" tools for client-server communications (GWT-RPC and RequestFactory for end-to-end protocols, AutoBeans for easy JSON serialization). With UiBinder, you can easily put to use your web designer skills.
if you're comfortable with JS, then go for it, but then you'd have to choose the "right toolkit" (jQuery? Google Closure?). Otherwise (which seems to be the case), it really depends how much "ajaxy" you need/want to be. I'm a strong believer in "one-page apps", but YMMV, or you can have specific constraints that rule it out. In any case, you'd have to choose a server-side technology.
So, depending on your needs/wants and skills, I'd choose GWT or "some JS toolkit". In any case, you'll have full control over the look and feel (unless you choose one of the bloated players: ExtJS/ExtGWT, SmartGWT or similar; you'll probably have a shorter time-to-market with these, but you'll pay it later, in terms of performance, integration with other toolkits, and look-and-feel).
In the light of what you're saying about your skills, I would definitely recommend GWT (despite your lack of experience with Java); because lack of experience with JavaScript is far worse than lack of experience with Java (you're talking about a "large application", so it's really important to start building things right and/or have tools to help refactoring, which you'll have with Java).
#ianmayo replied while I was writing the above, and I can only second what he said!
GWT is definitely not old or dying! A lot of Google's own applications are developed using GWT. You can download the GBST case study and learn how the global financial company uses GWT to improve productivity and create a rich user experience. You have to know that when you use GWT you automatically use javascript, html, etc. You create a your gwt application in java, but when you compile it gwt creates a folder with html files, javascript code, css, etc...
I definitely recommend it!
In order not to mislead readers with above seemingly unanimous answers, keep objective view in respected stackoverflow, following review expressed exact experiences I had with using GWT. Whether GWT is dying depends on how many new apps will adopt it,Google trend can tell (gwt trend).

>
I am both good and bad to answer this question - good, in that I've actually used it before, and bad, in that I was quite experienced with HTML/CSS/JavaScript prior to working with GWT. This left me maddened by using GWT in a way that other Java developers who don't really know DHTML may not have been.
GWT does what it says - it abstracts JavaScript and to some degree HTML into Java. To many developers, this sounds brilliant. However, we know, as Jeff Atwood puts it, all abstractions are failed abstractions (worth a read if considering GWT). With GWT, this specifically introduces the following problems:
Using HTML in GWT sucks.
As I said it, to some degree, even abstracts away HTML. It sounds good to a Java developer. But it's not. HTML is a document markup format. If you wanted to create Java objects to define a document, you would not use document markup elements. It is maddeningly verbose. It is also not controlled enough. In HTML there is essentially one way to write
<p>Hello how are <b>you</b>?</p>
In GWT, you have 3 child nodes (text, B, text) attached to a P node. You can either create the P first, or create the child nodes first. One of the child nodes might be the return result of a function. After a few months of development with many developers, trying to decipher what your HTML document looks like by tracing your GWT code is a headache-inducing process.
In the end, the team decided that maybe using HTMLPanel for all HTML was the right way to go. Now, you've lost many of GWT's advantages of having elements readily available to Java code to bind easily for data.
Using CSS in GWT sucks.
By attachment to HTML abstraction, this means that the way you have to use CSS is also different. It might have improved since I last used GWT (about 9 months ago), but at the time, CSS support was a mess. Because of the way GWT makes you create HTML, you often have levels of nodes that you didn't know were injected (any CSS dev knows how this can dramatically affect rendering). There were too many ways to embed or link CSS, resulting in a confusing mess of namespaces. On top of that you had the sprite support, which again sounds nice, but actually mutated your CSS and we had problems with it writing properties which we then had to explicitly overwrite later, or in some cases, thwarted our attempts to match our hand-coded CSS and having to just redesign it in ways that GWT didn't screw it up.
Union of problems, intersection of benefits
Any languages is going to have it's own set of problems and benefits. Whether you use it is a weighted formula based on those. When you have an abstraction, what you get is a union of all the problems, and an intersection of the benefits. JavaScript has it's problems, and is commonly derided among server-side engineers, but it also has quite a few features that are helpful for rapid web development. Think closures, syntax shorthand, ad-hoc objects, all of the stuff done by Jquery (like DOM querying by CSS selector). Now forget about using it in GWT!
Separation of concerns
We all know that as the size of a project grows, having good separation of concerns is critical. One of the most important is the separation between display and processing. GWT made this really hard. Probably not impossible, but the team I was on never came up with a good solution, and even when we thought we had, we always had one leaking into the other.
Desktop != Web
As #Berin Loritsch posted in the comments, the model or mindset GWT is built for is living applications, where a program has a living display tightly coupled with a processing engine. This sounds good because that's what so many feel the web is lacking. But there are two problems: A) The web is built on HTTP and this is inherently different. As I mentioned above, the technologies built on HTTP - HTML, CSS, even resource-loading and caching (images, etc.), have been built for that platform. B) Java developers who have been working on the web do not easily switch to this desktop-application mindset. Architecture in this world is an entirely different discipline. Flex developers would probably be more suited to GWT than Java web developers.
In conclusion...
GWT is capable of producing quick-and-dirty AJAX applications quite easily using just Java. If quick-and-dirty doesn't sound like what you want, don't use it. The company I was working for was a company that cared a lot about the end product, and it's sense of polish, both visual and interactive, to the user. For us front-end developers, this meant that we needed to control HTML, CSS, and JavaScript in ways that made using GWT like trying to play the piano with boxing gloves on
First of all , GWT is not dying technology, its usage increases, and its latest version is 2.2. I am using GWT for 2 years, since version 1.6. Its improvements since them is quite amazing.
Since GWT is client side technology, it does have only positive effects of your application scaliblity feature. Because server side web technologies such as jsf, struts, wicket are server resource consumers, but gwt does not need any server resource to render user interface..
But there is problem for your team. Because your team has no java experience, it would be quite difficult to adapt yourself two new technologies java and gwt.. If you have time to learn , I would strongly suggest GWT.
It takes approx 1 year to become proficient in GWT. Using GWT pays off if you develop an application as sophisticated as MicrosoftOffice or PhotoShop. It makes no sense to use GWT for small and relatively simple apps, IMHO. GWT is a time killing framework indeed, and you have to have very strong reasons to use it. I think that 99% of web apps don't need GWT.
GWT is not dying framework, but time killing framework. It has security issue. You can do easily CSRF(Cross site request forgery) request to the GWT applications. Also Java and Javascript are totally different languages, you can't translate easily. For your productivity avoid GWT.
I'm starting work on a smartGWT project in a few days and I'd like to know what kind of experiences you had. To avoid making this a bashing of smartGWT or GWT or a freestyle discussion, I'm going to provide some pointers for the discussion:
Do you feel that the provided widgets are integrated well? Is there any widget you miss in particular?
Have you encountered any problems when designing your application that were caused by the framework?
Is the datasource integration as usefull as the smartClient team claims?
What methods do you use to make your smartGWT application persistent? e.g. How well do Hibernate and smartGWT play with each other?
Feel free to add anything you feel is worth pointing out.
I guess you already have your answers, but I would like to add a few more comments that may affect your decision:
Pros:
SmartGWT is the most compreensive LGPL GWT-based widgetery library you can find. So if you care for GPL pain, this is your thing
Comprehensive Showcase.
Really good performance (just check the Showcase).
Very active community in the forums.
SmartGWT extensions is another important project. For example, it has support for GWT-RPC based communication, which is not possible only with SmartGWT (unless you implement your own integration).
Rapid pace of development from the SmartGWT guys. Just count the number of releases since the SmartGWT project appeared.
Cons:
Besides the Showcase, I sometimes feel the only way to figure out how something works is by asking in the forums. This leads to a spread knowledge base. A community based wiki would be preferable.
Large amount of static files you have to use with your application (the famous 'sc' directory) which might lead to problems if your back-end is in GAE (because of the 1000 files limit).
We used SmartGWT in our last project (duration: 6 months). The following is my personal opinion:
The widgets are really great! The documentation and API is verbose. We would use client-side again.
The server-side integration works, but did not save any development time. Instead we had a lot of problems where we had to find workarounds. Also, because of the new API, no other developer can maintain the project within investing a lot of time to learn the SmartGWT API.
Some Cons:
You have to learn a totally new API instead of using Hibernate and GWT-RPC or REST.
The data integration is done automatically, that is true. But if you need some (also little) changes, you have to write XML mapping files as with Hibernate or JDO. So the benefit is gone.
The forum support is bad: You get an answer to almost every posted question. But that answer often does not help. They ask you things such as “why do you want to do that”. Or they say: “use our tool and do XYZ with it” three times, although again and again I told them this suggestion does not work. After a few answers to a question the final answer is: “you need training, buy our support”.
The commercial support is way to expensive (costs approximately as much as the SmartGWT license).
We will probably not use the server-side integration of SmartGWT again.

Do you feel that the provided widgets
are integrated well? Is there any
widget you miss in particular?
You could create any missed widgets, there is no single framework that can provide everything you want. The widgets are pretty extendable.
Is the datasource integration as usefull as the smartClient team claims?
The data (JSON/XML) can be provided by servlet services, and they are understood by the
widgets.
What methods do you use to make your smartGWT application persistent? e.g. How well do
Hibernate and smartGWT play with each other?
In the backend servlet services of GWT, you can persist your data in the store by using any persistent layer in Java. Hibernate can be just used as same as normal java app.
Do you feel that the provided widgets are integrated well? Is there any widget you miss in particular?
Yes. The widgets have a consistent API and work well together.
Is the datasource integration as usefull as the smartClient team claims?
This IMO is one of their strongest feature. Once you start using their Datasource API you realize how little code is required to get a fully functional CRUD screen
What methods do you use to make your smartGWT application persistent? e.g. How well do Hibernate and smartGWT play with each other?
Hibernate works out of the box with the SmartGWT EE version. With the LGPL version using Glead works wells
I think SmartGWT has a ton of great widgets, but but but there is a HUGE price.
Create a simple SmartGWT based project and watch how many files get loaded by your page.
That, I think, is totally against the ideals of something like GWT. While SmartGWT may be a pretty good option for people on a deadline, if you want raw performance, stay away from it.
The number of HTTP requests will simply kill your application.
Have you encountered any problems when designing your application that were caused by the framework?
Yes. When I combined Google Eclipse plugin, SmartGWT, GWT 1.6.4, and Wicket the gwt compiler would emit bad javascript. By bad javascript, I mean javascrip that would not work in webkit, or firefox. I was not able to get good javascript until I removed it completely from the Eclipse project and restarted Eclipse. So, this combination would not work and I ended up building the SmartGWT piece separately in another project. The other issue is that the Smart client seems to want control of the whole page in a css sense. So, the integrated SmartGWT module was all messed up, because styles were not isolated properly. Your mileage may vary.
Personally if you use SmartGWT only and for everything then all will most likely be fine, but if you try and mix it, well my results were disastrous. So, I no longer use it.
Just as a counterpoint to the poster above who mentioned troubles with Wicket, the SmartClient forums (forums.smartclient.com) have reports of success integrating SmartGWT with a wide variety of other technologies. This poster's problems sound like 1) a GWT bug causing bad JavaScript and 2) CSS naming conflicts between SmartGWT and Wicket, probably neither framework's fault. All of SmartGWT's style names can be renamed via the skinning system to resolve any such conflict.
If you were going to start building web sites as a consulting business on the side -- keeping your day job -- and you also had a toddler and a wife, what frameworks/tools would you pick to save you typing?
Any language.
I'm looking for a productivity superstar stack that won't tie my hands too much when I have to update the site 6 months later, or "evolve" the data model once in production.
It needs to allow me to say "yes" to the client: community features, CMS, security, moderation, AJAX, ...
I would suggest Django. Super simple to get something up and running really quick. You are using Python which has a large library to go with it. For me Ruby on Rails would be a close second.
I'd probably look at DotNetNuke. Its easy to set up (a lot of hosts will do it for you) and easy to use and put together a custom site that business's will be able to maintain in the future.
Its fairly easy to create custom modules that are specific to a business and hundreds of modules for sale (or free) that can be integrated into DNN for special uses.
Take a look at Microsoft's Sharepoint server if you'd like a pre-made framework with many options for plugging in your own code. Sharepoint is kind of a world unto itself but it is a very powerful environment.
Update: I'm surprised to have been voted down on this one. Keep in mind that the questioner specifically requested frameworks that included a CMS. Sharepoint meets this criteria - unlike straight .NET or other web development frameworks.
If you are going to vote the entry down, I think you owe it to the person who asked the question to explain why you don't think he should not even explore it as an option. You could be right - collective wisdom is what voting on SO is all about. But without an explanation, we don't know why you think you are right.
My answers are going to revolve around the .NET stack.
Use Master pages and CSS templates. This makes it so much easier to pop in a new look and feel for your customer.
For sure I'd include the Dynamic Data framework in the .NET world.
Hosting might become an issue for your customer. Questions around managing email addresses, procedures on how to quickly update the website to include the new contact phone number (different for each customer, I'd assume) Consider getting a reseller account on your favorite webhost, and dole out webhosting accounts as appropriate. There are lots of issues around this point. It may turn out to be a nice source of recurring revenue.
Build yourself a few patterns including a database wrapper which would handle all your data calls (i.e. a dll which wraps all your data calls, sets up your ADO.NET objects, runs your sproc calls, and picks up the connstring from app.config or something similar.)
This goes a long way to maintainability as well.
I would recomend going with anything MVC in a language you can undertand! Theres a couple of CMS's in python, php and ruby using that design and well... that allows you to be ready for combat for Ajax and expanding anything very fast.
This is definitely not a question that can be answered.
I prefer asp.net webforms because I think it allows for extremely rapid web app development, but I am sure you will receive recommendations for:
asp.net mvc
Ruby on Rails
PHP and some framework
Python and some framework such as Django
I believe PHP has the most pre-built apps that you can use, though asp.net also has the things you are looking for.
All of these platforms and frameworks can do what you want.
Choose between Rails and Django. They both have different strengths. I like Rails better in general, but Django's admin interface can save you a lot of time when you need it.
There's another factor to take into consideration here: what are you the most familiar with? I believe that some studies have found upwards of a 30% loss of productivity when trying to learn a new language/framework.
Sometimes, there's nothing wrong with just sticking to what you know. But if you're interested in what languages/frameworks to learn, I'll refer you to the other posts because the above was the only thing I really have to add.
I recommend looking into Grails. It uses Groovy which is similiar to Java (so if you know this already you're good to go). Groovy runs on the JVM so you can still use all the great libraries already available for Java. Yet, since it's a dynamic language with a lot of the similar bells and whistles like Ruby you can use closures and that kind of neat stuff when you need/want to. And you're not slowed down by Java's traditonal slow compile-deploy-test development cycle.
Grails is already setup with Hibernate and Spring. You can create CRUD application in practically no-time (pretty much like Rails applications), and at the same time drill down and be able to control every little details since it's built on such proven and well-supported technologies. In addition there's literally hundreds of plugins available that helps you easily set up things like mailing lists, security, AJAX components and so on.
Otherwise, if you want to set up a community site and don't want to code a single line you could always check out ning.com.
