[jboss-user] [JBoss Messaging] - about transaction and order

In my case, ineed to process message by order, so i create a Session Bean (Processor) to do that, the code is like following: @TransactionAttribute(TransactionAttributeType.REQUIRED) public boolean process() throws BusinessException { try { Message message = poll(); if (message != null) { handle(message); return true; } } catch (Exception e) { logger.error("error", e); throw new BusinessException(e); } return false; } in the function poll(), i just create a MessageConsumer and call receive()。 in another job, call this session bean like this: processor.open(); try { while (processor.process()) ; } finally { processor.close(); } and in open() function, i create connection and session, and in close() function i close them. In my test, we put 10 messages into the queue, and the 5th one will process failed. I found several strange problems: 1、messages after the 5th one was processed 2、there are 2 messages left, one is the 5th How to explain these? And how to receive 1, 2, 3, 4, and then blocked.
