Transaction Problem

[dkalna]

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();
}

}

Only when you run the neueTx method through a business interface will it get a new transaction. Directly calling the method from within the bean won't trigger any tx features.
Please try:

ctx.getBusinessObject(SimpleRemote.class).neueTx();

Hello wolfc, thanks for replay...

i have implemented it, now I get following exception:

java.lang.IllegalStateException: Not implemented

I'm using JBoss-4.0.4GA... is it possible that this feature is not implemented, or something else?

Thanks a lot

ok, I've found the problem, after I installed EJB3.0-RC9 problem 'Not Implemented' disappeared.
