[Renegade_xx]

Hi!

I have a problem inconection with this error message.
I'm new in ejb3, and i've desided that i try to make the RUBiS (http://rubis.objectweb.org) project with enterprise beans in ejb3.

I have the following problem:

If there is the @PersistenceContext(unitName="rubis") annotation in the BrowseRegionBean.java, I get the following error messeage:

if i put it to comment, the javax.naming.NameNotFoundException is disappear, but in this case I get the following msg:

  | 10:52:04,000 ERROR [STDERR] java.rmi.RemoteException: Failed to executeQuery java.lang.NullPointerException
  | 10:52:04,000 ERROR [STDERR] 	at edu.rice.rubis.beans.Session.BrowseRegionBean.getRegions(BrowseRegionBean.java:47)

I know why I get the last message, bud I don't know how I can solve this problem

Please help me,
Thanks
