I want to reach the data saved in a mysql server for an Android phone. I thought about to connect directly the phone to the mysql but it is a bad practice because someone can get the user/pass of the DB.
However the REST architecture maybe it's a solution for my problem. I found the toolkit GWT but I don't know if it's the best way to solve my problem and what I need to use the GWT.
And I got 2 questions basically:
The GWT is good for my purpose?
Need a Tomcat server for example to set the GWT code?
One annotation, the data is for an app Android, there is no HTML interface .
Nowadays I'm working at localhost. Thanks for the answers.
As far as I understand, you want to implement a RESTful service (Web API). GWT targets the Web UI to be able to build it using Java and compile it into JavaScript. I think that it's not what you expect.
Here is a link that provides you hints about concepts of REST: https://templth.wordpress.com/2014/12/15/designing-a-web-api/. It will describe you what is a RESTful service and how to design it.
There are several technologies to build RESTful services (server-side frameworks). I can list two of them:
Restlet (see this link http://restlet.com/technical-resources/restlet-framework/tutorials/2.3 and http://restlet.com/products/restlet-framework/)
JAX-RS and its implementations (Restlet, Jersey, EasyRest). See this link for example: https://templth.wordpress.com/2015/03/06/getting-started-with-resteasy/.
Hope it helps you,

I am trying to get started with REST web development with java.
I've found a lot of tutorials where people write up sample RESTful web service and clients for them in Jersey. I do understand how they work and I am happy with my progress.
However, there are a couple of things that should be obvious (?) but are not so clear to me. All of the tutorials that I have gone through develop clients whose input and output is all done through the console. Is it possible to develop a client whose input and output is done through a web browser?
I've also had a quick look over JSP, which I understand is used to create dynamic web content. Is it feasible to create a Jersey client that uses JSP to get its input and print its output? I would be very grateful for any examples / sample code that demonstrate how this can be done, if this is something that can be done.
Thanks!
I am in the process of creating an app (cross-platform with Ionic framework) and during my research about app with this framework I found the one created for HabitRPG and it is using an API to retrieve data, it totally suits my app as well, but I don't know where to start to create an API nor what to use.
I allready did some quick test with Spring, NodeJS and Symfony (with FOS) but I'm looking for something really easy to use and to setup but still to have a lot of flexibility (like manage security, users, and data visibility).
Is there a specific technology easy enough to start with ?
If you want to create a Web API and host it, you can perhaps have the look at APISpark (http://restlet.com/products/apispark/). It's an online plateform that allows to design your APIs following REST principles and then host them. The data are also managed by the platform.
Hope it helps.

I'm trying to make a web server using java and jsp (it is a web server for an iPhone application). I don't know a lot about java so I'm having a lot of troubles trying to construct a server by myself. For now, I have tried implementing cookie, database, and some other methods. Now that I've given you basic information about my web server, I have a few questions to ask.
Is it the right approach to use java and jsp to make a web server like this? the java servlets get and send user inputs to different jsp pages, which contain some HTML and java code. But I've found some posts here that it's a bad practice to use jsp like this. I don't know how else I can make webpages. Could anyone please recommend the right approach to make a web server (like the one linked above)? I would love to know if there is some kind of a template that I can take a look at.
What you are making doesnt seem to be a "server" at all but rather a "web application" or "web site". The former implies you are creating a piece of sfotware to implement a specific protocol like HTTP, FTP, etc. while the latter is making a series of web pages or and application that runs on server.
You can create a web application in any number of languages, not just Java. From the screenshot you shared i would think that using Rails (Ruby), Django (Paython), or Symfony2 (PHP) would probably get you up and running pretty fast as it looks like you dont need much more than some basic model scaffolding with a pretty face.
If you are familiar with Java you might also want to try the Play! framework...
I need to interface a SOAP web service and, for demonstration purposes, I also need to show the API functionality in a graphical user interface.
I would like this interface to be simple, sleek and nice looking.
What's the best technology to create this UI? I'm familiar with Java, Javascript, CSS, HTML, XML, PHP, etc..
Well, there is are a bunch of different options. You can create an application from scratch using the technologies above.
I personally recommend the playframework at http://www.playframework.org, it provides a lightweight and easy to use Web Service API.
See http://www.playframework.org/documentation/1.2.4/libs#WebServiceclient for details.
PHP is also a very good option, but I think you will get up to speed faster with Play.
Node.js is another excellent option...
Not sure how far you need to go with your UI, if it's just a matter of showing the message being sent and the answer, SOAPui may be enough, there is osx SOAP Client and REST client for mac.
Looking for a recommendation of which framework/web server to go with on Linux. The idea is to build database backed RESTful web services.
I know Java, c++, c# (irrelevant I guess on linux) and C. Okay with developing in any of those.
Here is a table of frameworks that have varying degrees of support for REST and the languages they use.
You might want to check out RESTx. It is multi lingual: You can write code in Java, Python (server-side JavaScript coming soon). RESTx is specifically a platform for the creation of RESTful resources and web services. It is NOT a traditional application framework. DB backed web services are actually a specialty of RESTx: You identify the reusable components you want (in this case a JDBC capable DB access component), and then just configure it through the RESTful API or by filling out a small form in a browser. As a result, you get a new RESTful web service, which encapsulates the query you specified when creating the new resource.
I'm the lead developer on RESTx, so if you have any questions, please contact me or visit our forums.
If I were you I would go with Ruby 1.9.2 + Rails 3
they're fun and you get to learn something new
