[jboss-user] [JBoss Messaging] - problem in doProcess() method in a servlet that posts messag
My environment is: JBoss 5, Windows Vista.
I have written a servlet that will post messages to queue via a Session Bean Facade. Now
this is the error the Netbeans IDE is giving me: The IDE (Netbeans is telling me the
following:
incompatible types:
found: javax.jms.QueueSession.CreateProducer
required:javax.jms.MessageProducer
The error is right here on: messageProducer = session.createProducer(queue); in the
processRequest(...) method.
Therefore this is what I have in the doProcess method in this servlet,
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
| throws ServletException, IOException {
| response.setContentType("text/html;charset=UTF-8");
| String title=request.getParameter("title");
| String body=request.getParameter("body");
|
| if ((title!=null) && (body!=null)) {
|
| Queue queue = null;
| QueueConnection connection = null;
| QueueSession session = null;
| MessageProducer messageProducer = null;
| try {
|
| InitialContext ctx = new InitialContext();
| queue = (Queue) ctx.lookup("queue/mdb");
| QueueConnectionFactory factory =
| (QueueConnectionFactory)
ctx.lookup("ConnectionFactory");
| connection = factory.createQueueConnection();
| session =
connection.createQueueSession(false,QueueSession.AUTO_ACKNOWLEDGE);
|
| messageProducer = session.createProducer(queue);
|
| ObjectMessage message = session.createObjectMessage();
| // here we create a Queueing Entity, that will be sent in JMS message
| QueueingEntity e = new QueueingEntity();
| e.setTitle(title);
| e.setBody(body);
|
| message.setObject(e);
| messageProducer.send(message);
| messageProducer.close();
| connection.close();
| response.sendRedirect("ListMessages");
|
| } catch (JMSException ex) {
| ex.printStackTrace();
| } catch (NamingException ex) {
| ex.printStackTrace();
| }
|
| }
|
| PrintWriter out = response.getWriter();
| try {
| /* TODO output your page here
| out.println("<html>");
| out.println("<head>");
| out.println("<title>Servlet
ServletToPostMessagesOnDexSubmitQueue</title>");
| out.println("</head>");
| out.println("<body>");
| out.println("<h1>Servlet ServletToPostMessagesOnDexSubmitQueue
at " + request.getContextPath () + "</h1>");
| out.println("</body>");
| out.println("</html>");
| */
| } finally {
| out.close();
| }
| }
I am not able to figure this out, even though it looks like a simple Java problem.
Any suggestions are appreciated.
thanks
