Problem deploying spring - gwt application in JBoss 5.0.1 GA

[Suhas Bilaye]

Hi,

I am having an application which uses gwt at the client side and using the dispatcher servlet i have done the mapping for processing gwt requests. The GWT requests are Rpc requests and hence I am getting an exception on the jboss console which says

10:37:53,948 ERROR [[ibe]] Servlet.service() for servlet ibe threw exception
javax.servlet.ServletException: non-HTTP request or response

But if i run a simple gwt sample application i do not get this error.

Please suggest what should be done.

Thanks and Regards,

This was a bug which got fixed in 6.0.0.M1 of JBoss AS. Here's the discussion. Your workaround is to remove the jar file containing javax.servlet.* classes from your application packaging. See this too.

Thanks a ton,

I used the Jboss 4.2.2 GA for my deployment it works fine but still it shows the conflict while loading gwt-user.jar and jeee.jar saying that the conflict is with the javax.servlet.Servlet class
and hence these jars have not been loaded

What do you suggest should i continue with this jboss or should i switch to 6.0

Thanks and Regards,
