CMP, MySQL get NPE in JDBCEntityBridge.loadLoadGroups

[rudger]

Hell there,

i am trying to deploy a few entity beans in CMP with a mySQL DS. I am getter a wired error. (Especially cause its a NPE.)

The interfaces and deployment descriptors are generated by XDoclet.
The JBoss is Version 3.2 (means DS is deployed by mysql-ds.xml)

The Error is as follows:

16:51:53,843 ERROR [EntityContainer] Starting failed
java.lang.NullPointerException
at org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCEntityBridge.loadLoadGroups(JDBCEntityBridge.java:977)
at org.jboss.ejb.plugins.cmp.jdbc.bridge.JDBCEntityBridge.resolveRelationships(JDBCEntityBridge.java:290)

at org.jboss.ejb.plugins.CMPPersistenceManager.start(CMPPersistenceManager.java:152)
at org.jboss.ejb.EntityContainer.startService(EntityContainer.java:342)
...


(strange thing: if i change the order of the tags, the error always occurs before the last bean is deployed)


Can anyone solve this miracle?

Post some bean code snippet : bean declaration, cmp fields and especially cmr fields (relationships).

Found the mistake:

I had to add the
@ejb.bean primkey-field="[primary key]"
tag to make sure JBoss can create the tables.
