EntityManager and @PersistenceContext not found

[jerryeads52]

After building and deploying my app based on an Oracle database on JBoss 5.0.0.CR2 using jboss-seam-2.1.0.GA I can view the standard
SEAM Home page but after logging in using admin/"blank" when I try to view one of the lists links on the top of the home page I get this error:

Any help would be greatly appreciated.

look in the knowledgebase for AS 5 with seam. 4.2.3 is recommended.

Alex,
     AS5 or JBoss 5.0.0.CR2 exposes the Sun Reference implementation for XACML which is why I am using it.  Is there no other answer than going to JBoss 4.2.3 for jboss-seam 2.1.0.GA?  I am building an Attribute Based Access Control project and I need the XACML spec to make this achievable. 

Thanks
Jerry

Alex,
     Running my app built from jboss-seam 2.1.0.GA on JBoss 4.2.2.GA works as it should.  When will seam be compliant with JBoss 5.0?  I still need the XACML reference implementation.

Thanks
Jerry
