GWT RPC Serialization on web and app server

Hi All,

I am facing a very strange scenario here. We have a GWT application that runs perfectly fine when deployed on weblogic app server. So far this was going pretty smooth for us. Now we are preparing our app for production release. For that, as per our company standard, we have installed a web server on our integration machine which will communicate with app server (installed on the same integration machine). When we access our application via webserver, we are getting the incompatibleremoteservletexception

We are using Serializable objects instead of IsSerializable for all the RPC calls in our application. This works fine when the application is directly access via the application server.

Your help here would be really appreciated.
