Here is an update, I made a few typos, and took out DISTINCT, renamed some of the EJB-QL entities to be unique Descriptor-wide(does this matter?), and made the return type local(remote I think is wrong, but not related to the original problem).

This now modified XML file still throws the same error :

[23:24:01,608,ContainerFactory] Could not deploy file:/E:/programming/java/jboss
/jboss-3.0.0alpha/deploy/Default/XMLInsider.jar/
java.lang.NullPointerException

at org.jboss.ejb.plugins.cmp.jdbc.JDBCStoreManager.init(JDBCStoreManager
.java:117)
at org.jboss.ejb.plugins.CMPPersistenceManager.init(CMPPersistenceManage
r.java:141)


Here is the new XML file for reference.

Also, is it possible that my jbosscmp-jdbc.xml could be throwing the error? Here is that file.
