Sometimes consume message, sometimes doesn't...

Hello!

 

I have this code below and sometimes I can't consume a message, I get return null. But when I'll go to jboss admin-console and

search on "list durable messages" using the message selector as I used inside the code it is found.

 

Initially it happend when I call getMessage(..) inside a loop for(), so I thought it was a problem because of several calls. But happend again when just have

one call. It doesn't happen everytime, just sometimes

 

What could be wrong ??

 

 

ObjectMessage om = jms.getMessage( "queue/MyQueue", "cpf='" + p.getCpf().trim()+ "'");

 

public ObjectMessage getMessage( String lookup, String messageSelector) {

        Session session = null;

        Connection connection = null;

        ObjectMessage om = null;

        try {

            ConnectionFactory factory = (QueueConnectionFactory) getInitialContext().lookup("/ConnectionFactory");//java:/ConnectionFactory

            connection = factory.createConnection();

            session = connection.createSession(false, QueueSession.AUTO_ACKNOWLEDGE);

            Destination destination = (Destination) getInitialContext().lookup(lookup);

            MessageConsumer consumer = session.createConsumer(destination, messageSelector);

            connection.start();

            Message message = consumer.receive(5000);

            om = (ObjectMessage) message;

        } catch (Exception e) {}

     return om;

}
