We just finished our first GWT application, and we are pretty seasoned Java developers. The app is pretty simple, and it still took us about 2 months to figure out how we wanted to standardize our approach. I suppose since you'll be doing this yourself, you won't have much discussion on building a platform for your company. But still, just understanding the concepts new to GWT is quite a challenge. In our case, we are persisting data to a relation DB, so we had to figure out how to retrieve that, transform it into something GWT could use, serialize to browser, etc. All standard GWT stuff, but quite a learning curve. Since you've never written programs in C++ either, I'd say you should probably give yourself 6 months for your first Java/GWT app. -- Guy Rouillier --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: I am not a JAVA developer
Hi @SID, I recently switched over to GWT for my client side development from ASP.Net as well. In my case we're in the process of writing a full blown Enterprise Package which will be using GWT client side and .Net Server side. So, from my perspective it's actually been easier learning GWT than it's been going through all the different frameworks using ASP.Net and the cool thing is that you get away from the whole ASP.Net engine, which will in essence lessen the load and make you applications much more responsive. You're also breaking away from the page life cycle and trying to maintain multiple ASP.Net pages with some Ajax. With GWT your client side becomes a full blown client application running in the browser and from my side I would definitely recommend making the break away from ASP.Net. It literally took my team around 2 weeks to get set up with the IDEs and to get to know GWT. My sell to the company I'm working for was quite simply that we should follow the leaders of the perspective platforms. I believe that Google is the leader when it comes to client side and that (personall choice) MS is the leader when it comes to server side. So, our design is a mix of GWT doing server calls through WCF services. We're also designing an offline capability for our solutions which will be making use of Google Gears and will soon start playing with a tool where we can use the same code to run in a "smart client" environment. At this stage the company is still looking at using Silverlight instead of GWT, but if it comes down to myself and my team, the choice will definitely be GWT. I don't believe in making your clients plugin specific and even the Gears implementation will be swicth based. I hope this helps, if you need more information about where to start just ask. We went through quite a nice learning curve and have learned a lot of lessens while doing so :) Enjoy and good luck with the decision...

What will change, of course, is the runtime (and associated classes): JRE vs. CLR. But switching from ASP.NET to GWT+(some server-side runtime) also means switching mind from a "full-AJAX" app vs. server-generated HTML +JavaScript (no more "postbacks", even less UpdatePanel and its "async postbacks"; everything is client-side with GWT and you basically exchange only data with the server side of your app). Now, switching from ASP.NET to servlets is quite easy if you already used HttpHandlers; and GWT-RPC is similar (in use) to ASP.NET AJAX's page methods. > > I am also considering DRUPAL as another alternative.

And I don't understand how Drupal can even be compared to GWT+(some server-side) or ASP.NET... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Just out of curiousity, why do you want to use GWT if your expertise is ASP.NET and you don't have any knowledge of Java? Is it a decision from "above"? There are a couple of frameworks and tools available for ASP.NET (I don't know but I'm quite sure about that ;-) so if you just want to have a GUI-toolset you might check out solutions that cover your knowledge instead of forcing yourself to learn something completely new. > If I decide to use GWT and JAVA, how much time will it take to learn > and use it for my this project? Will it be tough? Do you think it is a > good idea to use GWT for my current requirement? The GWT-part is not hard, if you know Java. There are GUI- designers out there that help you create the GUI of appli- cations without programming any line of code (like the designer shipped with Visual Studio that you should know). But you have to know learn Java for implementing the logic and - if you want to use the GWT-RPC-mechanism - the server- side functionality. > Though I have never used, but I have learned C, C++ during my studies. C and - better - C++ helps to learn Java, but there are some differences you have to learn, like the way parameters are passed to methods and the lack of "pointers". There should be a couple of tutorials out there helping to switch from C++ to Java. > As of now, Only I will be working on this project, and there might be > 1 more consultant in the future.

Re: I am not a JAVA developer
Hi I'm not expert, but i would say is: 1) Download GWT and give the examples a try. 2) Visit: http://examples.roughian.com/ . Its a good site of reference to see the different widgets, and how to use them. 3) I've done ASP before and java is so much easier.(But that's just a personal experience, it not something set in stone, :) ). 4)I think could could accomplish your requirements using GWT. 5) Good luck, :).
