An IncompatibleRemoteServiceException was thrown

Hi,

An application I build with GWT 2.1 in Eclipse (v3.5, Classic) worked
just fine in tomcat. However, I've upgraded my environment to Eclipse
Indigo (EE version) and GWT 2.3 and the same app will not run on the
production servers, but builds and runs fine in the development
environment. Since I'm testing GlassFish with the intention of moving
away from Tomcat, I tried the app there and got an extensive stack
trace error report:

WebModule[/AccountRequest]AuthenService: An
IncompatibleRemoteServiceException was thrown while processing this
call.

Since the app was simply imported and not built from scratch on
Indigo, are there settings I need to play with? Any ideas?

Thanks,
