To view the discussion, visit: https://community.jboss.org/message/726282#726282 -------------------------------------------------------------- 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.             warxsg -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/726282#726282] Start a new discussion in EJB3 at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
