EJBs and Transactions

[nigelwhite]

I'm not too sure abuot "Transactions", I thought they were something to do with databases, but they appear to be something to do with EJBs....

Anyway, in one of my EJBs, I create a HibernateEntityManagerFactory. The createEntityManagerFactory() call fails with

13:10:09,203 ERROR [SchemaUpdate] could not complete schema update
java.sql.SQLException: You cannot commit during a managed transaction!
 at org.jboss.resource.adapter.jdbc.BaseWrapperManagedConnection.jdbcCommit(BaseWrapperManagedConnection.java:496)

Something to do with the EJB starting a Transaction? How do I get the call to createEntityManagerFactory NOT to use a "ManagedTransaction"???

It appears to be an older version of Hibernate.

What version of JBoss AS and EJB3 are you using?

After some googling and trying random incantations, I ended up wit hthis at the top of the EJB methods which create an EntityManagerFactory:

@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)

Who'd a thunk it?
