In the EJB spec, it says that the bean's remote & home interfaces must have
valid return and parameter types for RMI remote interfaces.
That is basically serializable objects or remote objects.
But can a bean method really return anything implementing java.rmi.Remote
[i.e., any remote object]? Or does it really have to be an object that
implements EJBObject [i.e, an Ebean]?
I tried it out with WebLogic and got the following exception shown below on
the client. Note the line marked with "***"; the error message is a bit
confused, but seems to not like marshalling an object that implements [an
interface that extends] Remote.
It seems to me that you should only be able to return EBeans or serializable
objects. Ifthat's the case, the spec. really should say so.
