[jboss-user] [EJB 3.0] - Transaction Problem

Hello, please help me, I'm stuck... my code is below, simple Stateless EJB with teo methods, both are REQUIRES_NEW annotated, in first one doSomething I read one row from DB, then I call second method neueTx, which I suppose will run in separate TX. Inside neueTX I call setRollbackOnly() to mark this TX for rollback, so new row (2, Jane) will be rolled back. Now back in doSomething I try to write changes for first row, but then I get following Exception: EntityManager must be access within a transaction Am I missing something simple? Thanks a lot Here is my code: @Stateless @Remote(value=SimpleRemote.class) public class SimpleRemoteBean implements SimpleRemote { static Logger logger = Logger.getLogger(SimpleRemoteBean.class); @Resource SessionContext ctx; @PersistenceContext EntityManager em; @TransactionAttribute(value=TransactionAttributeType.REQUIRES_NEW) public void doSomething() { Test test = em.find(Test.class, new Long(1)); neueTx(); // should be running in separate TX, or not? test.setName("Lukas"); em.merge(test); // I expect this to be writen in DB successfully } @TransactionAttribute(value=TransactionAttributeType.REQUIRES_NEW) private void neueTx() { Test test = new Test(); test.setId(2); test.setName("Jane"); em.persist(test); ctx.setRollbackOnly(); } } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3979968#...
