No Transaction in ActionHandler

[sirlantis]

Hello everybody,

I am currently writing an ActionHandler for my jBPM process. This ActionHandler is invoked by an async timer. What the handler does is:

@Transactional
function execute()
{
     entityManager = Component.getInstance(...)
     stuff = getStuffInstanceFromProcess
     message = entityManager.findUnprocessedMessages
     whatToDo = parse(message);
     stuff.update(whatToDo);
     message.setProcessed(true);
     
     entityManager.merge(message);
     entityManager.merge(stuff);
}

Now the problem is, that neither the message nor the stuff is updated. I believe that's because there is no transaction active (since entityManager.flush raises an no-transaction-exception). Also, Seam does not have any interceptors around my callstack, which would flush a transaction automatically.

As a sidenote: I already tried to annotate my handler class with the following:

@Stateless
@Name("checkForExecutableMessages")
@Interceptors(SeamInterceptor.class)

Anybody knows, what I could do about it?

Thanks in advance,
Marcel

@Transactional

annotation is for use with non-EJB components only.

Is your async timer an EJB3 timer ?

If you turn your handler class into a stateless EJB, thats how you did it with

@Stateless

then the default transactional behavior is REQUIRED and should work.

I don't know why you put

@Interceptors(SeamInterceptor.class

I don't think you should put this directly. The

@Name

annotation is sufficient to make it a Seam managed component.

Are you running inside jboss 4.2.2 ?
