Jms error handling

Question

Hi,
          I send an xml-file on a jms-queue... When the xml-file is invalid, (eg. blabla), the xml-file is redirected to an error-jms-queue...
          I've a listener on this queue. I want to receive the incoming message, but all I get to see, (I think) are a few characters... I supose it's some kind of address...
          Has anyone an idea how I can get, the data that the user has send? This is very trivial...
          Here is the code of my listener of my error-jms-queue
          * @ejbgen:message-driven
          * clients-on-same-server="true"
          * destination-jndi-name="test.error"
          * ejb-name = MdbError
          * destination-type = javax.jms.Queue
          public class MdbError
          extends GenericMessageDrivenBean
          implements MessageDrivenBean, MessageListener
          private static Logger log = Logger.getLogger("wlw.Error");
          public void onMessage(Message msg) {
          try {
          msg.acknowledge();
          BytesMessage mesg = (BytesMessage)msg;
          } catch (Exception e ){
          System.out.println("exception... => " + e);
          Thx in advance...

Hi,
          this gives a ClassCastException.
          I've this test in my errorHandling:
          if (msg instanceof TextMessage)
          System.out.println("TextMessage: " + ((TextMessage) msg).getText());
          else if(msg instanceof ObjectMessage)
          System.out.println("ObjectMessage: " + ((ObjectMessage)msg).getObject());
          else if(msg instanceof StreamMessage)
          System.out.println("StreamMessage: " + ((StreamMessage)msg).readString());
          else if(msg instanceof BytesMessage)
          char t = ((BytesMessage)msg).readChar();
          System.out.println("BytesMessage: " + ((BytesMessage)msg).readUTF());
          else if(msg instanceof MapMessage)
          System.out.println("MapMessage: " + ((MapMessage)msg).getString("msg"));
          I always gets a message of type BytesMessage.
          Thx in advance
