Links to any sample gwt project using requestFactory, activites and places?
Thank you.
I found this post from David Chandler very helpful. It discusses a sample project (source code here) using Request Factory, Objectify and Activities and Places.
The project is also discussed in this Google I/O talk. The difference from the original project is that in the talk they use GWTP for the MVP part. You should check out GWTP also as it really simplifies developing with MVP.
My experience with the roo plugin for GWT and GAE wasn't very good. It wasn't very mature when I looked at it (around March 2011), but maybe things have changed since then. For example you had to compile from trunk, as the latest stable version had some bugs, and even then a many to many relation between entities wasn't supported. Documentation was kind of scarce also.
The MobileWebApp sample from the GWT SDK ?

Is there at least anything other than Vogella's tutorials and his book, which is completely based on those tuts? Examples from his repo are often either incomplete/unfinished/won't run and those examples even don't match the book actually..
I'd like to find at least some javadoc for this, because any step to a side and I'm completely lost on how to accomplish different tasks and what functionality is available.
Lars Vogel's Tutorials are the most complete and up-to-date documentation on Eclipse 4 development. Second to this is asking questions in Eclipse 4 Community Forum. Last option is to google for specific technical problems, which will in most cases lead you to blog posts from the same people that are active on the forums. (Mainly single supporters like Lars, some Eclipse devs and the guys from www.eclipsesource.com)
I discourage using the wiki, since much of the information may be outdated and may be more confusing than an actual help. Documentation for JFace and SWT can be reused from Eclipse 3.x since there are few to none changes in Eclipse E4.
E4 is alive and many of its components are now encapsulated in the standard Eclipse Platform. So most of Eclipse 3 docs and books are still relevant, as well as the Eclipse 4 ones.
If you want to understand the theory, you should start searching Eclipse conference slides explaining the Eclipse Platform and plug-ins. Trust me, it might sound old-style, but most of the times I find an EclipseCon Powerpoint or PDF, it is a great presentation, concentrating in 30 minutes the great work of some of the best Eclipse developers. If I had to re-start learning Eclipse, I would start again from some EclipseCon slides talking about Eclipse Plugins and Eclipse E4 Model.
For Eclipse4 or E4, we mean the Eclipse4 Model, which is now part of the Eclipse Platform. The Eclipse IDE itself supports both 3.x and Eclipse4 programming.
If you want to start Eclipse4, you should take a good book or a tutorial and follow it step by step. As an example you have these books:
Eclipse RCP (Rich Client Platform) 2nd edition
Contributing to the Eclipse IDE Project (free ebook)
Eclipse 4 Plug-in Development by Example: Beginner's Guide
Instant Eclipse 4 RCP Development How-to
However, there are a lot of sources of information, as many books, web tutorials and blogs. You can find most of them here:
https://wiki.eclipse.org/Eclipse_Articles,_Tutorials,_Demos,_Books,_and_More
https://wiki.eclipse.org/Eclipse4/Tutorials
http://planeteclipse.org/planet/
In my personal list of who to follow, I could include: Vogella RCP, EclipseSource, Tom Schindl, OpCoach, RCPVision, Kai Toedter, AllBlue, Wim Yongman, and all the E4 Contributors who are writing articles. But it is unfair not to mention all of them.
If you're not satisfied by docs and tutorials, please file a bug to the Eclipse Platform; mention "missing documents to use E4" and specify what you need. The Platform UI team will take care of this, either by linking the existing documentation to the above wiki page or by creating the missing docs.
Note: Several of the developers of the Eclipse E4 and Platform team contributed to the success of the technology by fixing bugs, writing code, documents, tutorials, and opening businesses based on this.
Eclipse committers are writing most of the existing documents, and they usually go to conferences. So, usually, you get their very best at the Eclipse Conferences. If you get their slides, you can get the best of some Eclipse and Java Champions, condensed in 30 slides, or in a video of 30 minutes.
You can start contributing to open source, by following tutorials, like those written by Eclipse Committers, and then you can give back by writing documents to capture your achievements ;)
But, keep in mind that a tutorial is not a book. There is a different process behind. Thankfully those great developers found the time to write code and documentation at the same time.
i was in the same position for my sparetime RCP-Project and was about to give up
since Neon the situation has been improved a lot
my approach
take the tycho-Example from vogella for headless-build
add your custom parts with 'hello world' and play around to learn
for database-access use a declarative Service using jpa
an example will be
http://relations-rcp.sourceforge.net/
for logging and error-view
https://github.com/buchen/portfolio
this project eye-opening!
in general:
search Application.e4xmi in Github by date descending and you will find excelent examples and full working products
Forget about e3 and stick to plain e4. Take Advantage of the latest api's
make a i18n plugin and use
#Inject
#Translation
Messages messages;
use ISideEffect as Binding
for me it becomes fun to code with e4
After almost 2 years there has been no decent response to this question. So i'm considering the Eclipse E4 platform efectively dead, as there are still people voting for this question and can't find an answer.
The only answer I have is - move to the NetBeans Platform. There are similar problems there, but at least people do answer in the mailing list and there are books which are quite more recent and are actually providing working source code! Enve the NetBeans website provides free tutorial on a lot of stuff for free!
I mean it's really hard to believe, but you should try NetBeans platform - it's the only choice.
For anyone who stumbles here looking for an e4 example, here's a simple basic example on using eclipse 4 rcpeclipse 4: rcp getting started
Standard Eclipse documentation for version 4.3 (Kepler) contains javadoc for the most part of e4 project:

Is three20 still actively being developed? From the three20.info site, I see no new features/UI elements since earlier this year when I looked into it.
Besides three20, is there another good framework out there?
As far as i know, Three20 is only maintained by community (bug fixes). Jeff left the project and decided to clean up that mess & provide solid documentation.
He recently started a new project on github called Nimbus, his plan is to port all features of Three20 to Nimbus without the problems we face today with Three20.
I haven't given up on three20 yet. It's a good framework and it saves me hours of work. I'm submitting bug fixes and small improvements to the framework from time to time and I see some activity in github. (not as much as it used to be)
I tried using nimbus, and I was really impressed with the documentation and existing classes. However, note that the developer went to work in CA and said he'll contribute less to his new framework.
The three20.info site is not maintained, but you can download the latest version from github.com/facebook/three20.
We are in the process choosing a new GUI platform. Ive been looking at subj. but are a bit confused. Could someone please refer to at tutorial or blog that makes a qualified comparison.
Thanks.

We've used SmartGWT for a couple of projects and it's ok but there are tradeoffs:
PRO:
Makes it easy to write a web app that looks and works like a rich client GUI.
Don't have to know any Javascript. SmartGWT coding is pretty similar to Swing coding, which is good if you already know how to do that.
CON:
Unless you do a lot of work tinkering with the look and feel, your app won't look very web-like, it will look like a rich client app running in a browser. You may not care about this.
It's a pretty heavyweight library which has to download large .js files to get going.
We found it difficult to control the layout of form controls precisely, but that might just be our inexperience.
I think you should fully understand what GWT does and what your projects needs are first and foremost. There wont be a source that will adequately compare them for your specific needs.
Start with the wikipedia http://en.wikipedia.org/wiki/Google_Web_Toolkit
Here is a comparison of SmartGWT vs GWT
http://www.theserverside.com/discussions/thread.tss?thread_id=60186
If interested in AJAX RIA Frameworts, below analysis is for you
Before starting new GUI for our new project arrival, I made some research.
Here are my findings (remove spaces from "http: // "; bcoz stackoverflow is preventing me to do so :)):
Prototype framework favorable links:

Dojo framework favorable links:

jQuery framework favorable links:

Test speed of different RIA frameworks:

More comparasions:
http://en.wikipedia.org/wiki/Comparison_of_JavaScript_frameworks
http://jqueryvsmootools.com/#conclusion
Out of all these findings I started using SmartClient 5. Initially we faced some issues but as SmartClient matures I find it interesting in many terms:
1. APIs doc help and examples
2. Flexible controls
3. Forum
Today I am working on SmartClient 8 and few on my GUIs are in production running successfully. Actually the great help with SmartClient is that you find every thing at one place. No need to dug many other sites that is hard to do for any other open source RIA framework.
So my choice is no doubt SmartClient.

I have been reading Groovy, and I'm half way down. I started to love groovy a lot, and apply it to solve some simple real world problem; As I love building web applications, i would go for reading Grails webframework as I know Groovy.
But If I want to build desktop-applications, which framework will be the good choice? I wanted to create a simple IDE for Groovy language(or say for any language), that can do syntax highlighting and other kind of stuffs.As mentioned earlier, I love Groovy a lot when compared to Java; And Griffon is a framework that is built on Groovy, mainly for creating Desktop-appplications. But I didn't find enough resources for Griffon!
Is Griffon is the good framework for those people who know and love Groovy(as I do)? Can I choose it for building a simple IDE as mentioned above? Or there are any other framework that is built on Groovy, which is good when compare to Griffon?
The problem I have found with Griffon is that a number of the plugins are a bit out of date in that they aren't using the latest UI libraries (e.g. Flamingo, Substance, and SwingXBuilder, altho I think this has just been upgraded to use SwingX 1.6).
I am using SwingBuilder directly, with a few extensions I have added via my own builder implementation:
http://code.google.com/p/ousia
If you want to build an IDE I can recommend the RSyntaxTextArea component, as it has great support for many programming languages and is pretty simple to use:
http://fifesoft.com/rsyntaxtextarea/
Griffon is a fairly good MVC based framework, and is built on top of Java Swing. So it can do anything that Swing can do.
To be honest I found Griffon a little too much for relatively simple UIs, so I usually write my apps in Groovy using SwingBuilder directly.
If you really want to get into Griffon I recommend getting the Book
Griffon in Action It seems to be the only place where everything is documented, although the web page is coming along and improving all the time.
There are definitely various resources out there that will let you learn more about Griffon, for example the Griffon Guide -> http://dist.codehaus.org/griffon/guide/index.html
"Griffon in Action" is another popular resource which you can buy in electronic form today; being the author of both makes me a little biased ;-)
You can keep up to date on Griffon news by following the mailing lists and #theaviary on Twitter
I am considering solutions for drawing diagrams using Google Web Toolkit (GWT).
Up until now I have found only the gwt-diagrams project but it seems abandoned.
Are there any suggestions about diagramming with GWT?
I'm also looking into this, for drawing family trees. I'm currently prototyping with gwt-graphics, which looks to be actively developed and is nearing version 1.0.
There is also the Raphael javascript library, and a couple of thorough blog posts about wrapping GWT around them here and here. The guys in the first article actually released their code for as raphaelgwt.
I can't comment on any of the raphael stuff yet since I haven't used it, I just found this in my own research for drawing components.
You can use draw2d and gef(eclipse Graphical Editing Framework) to develop your GWT Diagram App Now.
look at this: http://code.google.com/p/trufun-webrcp/
the GWT framework with completely open source based on html5 technology, is used to transplant eclipse RCP to GWT WEB.
I would use Google Chart Tools: http://code.google.com/apis/charttools/
I am actually working on a GWT library to draw diagrams and add widgets on the connections. Here is the project site http://code.google.com/p/gwt-links, you'll find a demo site and a video demonstration.
