Strange corba exception

Question

Hello,
Our application uses only local interfaces til yesterday.
Then I need to return some of our entity classes through remote interfaces, but then comes the following:
In the session bean, I return a "filled" User instance, but the client only gets an "empty" one (all fields are null).

All classes have serialVersionUID's set.
The application is running on jdk6. I've tried to switch to jdk5, but without success.
If needed, I can try to paste relevant code parts.
Hope somebody can help
Dirk

Answer 1

The problem is not at the entities classes.
If I look the service up from an external application, I get the current result.
But if I look call it from another web application (in the same glassfish), I get the above exception.
Could the lib distribution be the cause of the problem?
MyApp.ear
- lib/myapp-api.jar
- myapp-ejb.jar
- myapp-web.jar
Service-web.war
- Web-inf/lib/myapp-api.jar
The myapp-api.jar (in ear/lib/) containts the remote interfaces and the entity classes) and the myapp-impl.jar containts the session bean implementations
The Service-web.war has its own copy of the api.jar.
The exception above comes, when using the services from the impl.jar in the service webapp.
