Thank you for taking the time to look at this.

So that should have skipped the persistence unit from deploying. But i will have to look at this once more to see if that's not how its expected to behave.

The JAR containing the  persistence unit is located in WEB-INF/lib/xxx.jar.

According to the EJB 3 persistence spec (JPA 1.0) section 6.2, the following location may contain the root of a persistence unit (root means the jar file or directory whose META-INF directory contains the persistence.xml):

  |   | * an EJB-JAR file
  |   | * the WEB-INF/classes directory of a WAR file
  |   | * a jar file in the WEB-INF/lib directory of a WAR file
  |   | * a jar file in the root of the EAR
  |   | * a jar file in the EAR library directory
  |   | * an application client jar file
  |   | 

That means that the persistence unit should be scanned with this type of packaging (item 3 in the list above).

Is there a way in JBoss (or generally in JEE) to prevent this scanning?

Thank you,
