Hello, I've got a similar problem: some attributes defined as LAZY causes a SerializationException and later on a ClassCastException when serialized to the client. When I configure them as EAGER it works, but a SerializaionException is thrown on bean passivation.
The configuration of the attributes is @ManyToOne(optional=true,fetch = FetchType.LAZY, cascade = CascadeType.REFRESH) or @ManyToOne(optional=false,fetch = FetchType.LAZY, cascade = CascadeType.REFRESH) I use JBoss 4.0.4RC1 including ejb3, using the installer. I have seen that there are different hibernate-libraries in server\\lib and server\\deploy\ejb3.deployer with different size. I've deleted the libraries in deploy\ejb3.deployer, on client side I use the librarires in the lib directory. It didn't change anything, the errror is still there. My client testclass (JUnit called in Eclipse) calls a StatefulSessionBean BeanA that calls a StatefulSessionBean BeanB, BeanB creates the hibernate object and reads the data. When I use only one StatefulSessionBean it seems to work (very confusing), but our apllication architecture uses 2 SessionBeans and we can't change this in a foreseeable timeframe. Any idea ?
