Methods Not Allowed in Container-Managed Transactions

You should not invoke any method that might interfere with the transaction boundaries set by the container. The list of prohibited methods follows:

• The commit, setAutoCommit, and rollback methods of java.sql.Connection

• The getUserTransaction method of javax.ejb.EJBContext

• Any method of javax.transaction.UserTransaction

You can, however, use these methods to set boundaries in application-managed transactions.
