Well, I'm on with my learning and now running into another problem. I've been
racking my head for 3 hours now and have opened up the source examples I got
with the book from JBoss, and I'm just stuck.
1) Is there a way to turn on really high debugging on the server so that I can
see what's going on during this EJB's run? I'm getting errors on the remote
client that aren't as helpful as the ones I might get from the EJB Container.
2) Here's my error I'm getting when I try to ask for a data element view:
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 userId
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
userId
Embedded Exception
Unable to load to deserialize result: java.io.StreamCorruptedException: invalid
stream header
at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:292)
Let me know what I screwed up now. I know I'm close! :)
I've looked through all the examples and I know I'm close. Just for some
background, I am only trying to get the User for a Playlist (one-to-one), so
it's really nothing special. I followed the cmp-example from the docs
subscription, as well as followed my Wrox Pro EJB book.
If you need anything else, please let me know!
