I have a ejb 3.0 sfsb with the EntityManager injected, using ejb2.1 clients.
In the @Init methods, the sfsb looks up the entity to work on. Strangely enough this sometimes fails with the following exception (only relevant part )
Caused by: javax.persistence.TransactionRequiredException: EntityManager must be access within a transaction
at org.jboss.ejb3.entity.ManagedEntityManagerFactory.getSession(ManagedEntityManagerFactory.java:117)
at org.jboss.ejb3.entity.InjectedEntityManager.getSession(InjectedEntityManager.java:149)

... 18 more
How can I prevent this exception?
