Hi all,

I have a Session bean:

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)

The session bean calls an entity bean and save the name and the surname in table called Customer

I wanted to manage the transaction from a Java Client so  I wrote a Java the following code :

  userTx = (UserTransaction) ctx.lookup("UserTransaction");
   userTx.begin();
    customerCreation.createSimpleCustomer("TestName", "TestSurname");
   userTx.commit();


When I run my  class I have the error:

[STDERR] javax.persistence.TransactionRequiredException: EntityManager must be access within a transaction
[STDERR]           at org.jboss.jpa.deployment.ManagedEntityManagerFactory.verifyInTx(ManagedEntityManagerFactory.java:155)
[STDERR]           at org.jboss.jpa.tx.TransactionScopedEntityManager.persist(TransactionScopedEntityManager.java:186)
[STDERR]           at com.allianzppu.b2x.CustomerCreation.createSimpleCustomer(CustomerCreation.java:47)

If I manage the transaction inside the mehod of my session bean everything works.
Any suggestion ?
Cheers.
