Well, that fixed my problem on the User end, but I'm still geting the same error
on the Playlist end as:
Exception in thread "main" java.rmi.ServerException: RemoteException occurred in
server thread; nested exception is:
java.rmi.ServerException: Internal error getting results for field member us
erId
Embedded Exception
Unable to load to deserialize result: java.io.StreamCorruptedException: invalid
stream header; nested exception is:
javax.ejb.EJBException: Internal error getting results for field member user
Id
Embedded Exception
Unable to load to deserialize result: java.io.StreamCorruptedException: invalid
stream header
at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:292)
...snip...
Which field member? Which object? I'm lost?
I changed my relationship to:
(changed multiplicity on role PlaylistBean to "Many")
<relationships>
<ejb-relation>
<ejb-relation-name>PlaylistBean-UserBean</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>PlaylistBean</ejb-relationship-role-name
>
<multiplicity>Many</multiplicity>
<relationship-role-source>
<ejb-name>PlaylistBean</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>user</cmr-field-name>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>UserBean</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source>
<ejb-name>UserBean</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
</ejb-relation>
