Part of my application's requirements involve me saving the transaction id of
some operations. I am using a CMT StatelessSessionBean. I thought that I
could get the id via entityManager.getTransaction(), but that yields the
following IllegalStateException. Is there another way to get to this
information without switching to user managed transactions?
| java.lang.IllegalStateException: Illegal to call this method from injected,
managed EntityManager

org.jboss.ejb3.entity.TransactionScopedEntityManager.getTransaction(TransactionScopedEntityManager.java:226)

Relevant portions of the class that is generating this error:
| package com.noverant.service.audit;
|
| import ...
|
| @Stateless (name="AuditService")
| public class StatelessAuditService implements AuditService
| {
| protected EntityManager entityManager = null;
| protected SessionContext sessionContext = null;
|
| @PersistenceContext(unitName = "nets-system")
| public void setEntityManager(EntityManager entityManager)
| {
| this.entityManager = entityManager;
| }
|
| @Resource
| public void setSessionContext(SessionContext sessionContext)
| {
| this.sessionContext = sessionContext;
| }
|
| public void addEntry(AuditEntry ae)
| {
| String transactionId =
entityManager.getTransaction().toString();
| }
|
| }
