Hi,

I would like to know if it is possible to a pass plain java object ( POJO ) to an EJB method eg. a create method or business method on a session bean. I am using Local Interfaces on my EJB, but receive a linkage errors when I try to do this ( java.lang.LinkageError: loader constraints violated when linking ). I am using Sun ONE Studio 5 with Sun Application Server 7.

Thanks
 
Well, one of the J2EE Patterns (TransferObject) requires that an EJB (in this case a Facade Stateless Session Bean) take in a POJO object in its parameters, so it should work for you.

The LinkageError indicates that some class that your POJO uses has incompatibly changed since the POJO was last compiled. Suggest you recompile the entire server app and redeploy.

Thank you for the reply Tim.

The POJO that I was trying to pass to the EJB method was defined within a web module. This caused the Linkage error.
