GWT - RPC Failure with GAE - Working in local on Greetings sample

Question

I'm encountering a probem with my GWT app. Everything is working great in local but I got Error 500 when the application is deployed on Google App Engine.

To understand the problem, I tried to deploy the sample Web Application example with Greetings service and I still got the same error Remote Procedure Call - Failure.

I think it's coming from my IDE settings but can't figure out what is the problem. Can anyone help ?

Seems like with the servlet paths .can you show us your web.xml and how you are accessing from browser after deploy ?? — Suresh Atta, Feb 18 '13 at 18:11
Nothing has been changed on web.xml. I just used the auto-generated Greetings sample in order to test : http://pastebin.com/QRHa6zfz — user2084280, Feb 18 '13 at 18:31
You can access the web app at this URL : http://www.urlgone.com/ed095d/ — user2084280, Feb 18 '13 at 18:33
Sure. Thanks for help. I got the following sequence of Error-Warning-Critical each time I try to call the RPC : http://pastebin.com/iR3CY0zm — user2084280, Feb 18 '13 at 18:43
My application is deployed with Google App Engine which is different from Tomcat, isn't it ? — user2084280, Feb 18 '13 at 18:58

The problem you are facing is with ONLY servlet paths .

The environment and the folder structure will be cmpletely different in Dev-Mode and Deployment environment .

What do you mean by ONLY servlet paths ? The servlet path /mywebapp/greet seems to be good as I can reach it (could not complete request but not a 404). – user2084280 Feb 18 '13 at 18:56
As the discussion in the above link are you working on mac ?? – Suresh Atta Feb 18 '13 at 19:02
I am not but I don't think it does matter. I work on Eclipse with GWT plugin and App Engine plugin. I deploy the project directly from this plugin. – user2084280 Feb 18 '13 at 19:06
Unpack your war and Have you checked that GreentingServiceImpl class is there ? – Suresh Atta Feb 18 '13 at 19:08
Of course it is : I didn't change nothing from the auto generated built in sample code – user2084280 Feb 18 '13 at 19:09
OOPs then thats the JDK version problem seems like .checkout http://stackoverflow.com/questions/10712034/app-works-fine-localy-but-it-wont-launch-on-gae – Suresh Atta Feb 18 '13 at 19:13
As I thought, that was an IDE problem. I clean up libraries : installation, paths, build settings and install a proper version of GAE plugin and it now seems to work. Thanks for help. – user2084280 Feb 18 '13 at 20:00
