Subscriber does not receive data from MDB

Question

The mapMessage.getString() is allways null in the following run method of a Thread. The same in the MDB direct outputs data.
public void run() {
     while (true) {
          try{
               System.out.println("run...");
               Message msg = getSubscriber().receive(0);
               MapMessage mapMessage = (MapMessage) msg;
               String rssfeed = mapMessage.getString("rssfeed");
               this.applet.rssfeed = rssfeed;
               System.out.println("feed: " + rssfeed);
          }catch(Exception e){
               e.printStackTrace();
          applet.repaint();
}There is a Warning-message if JBoss4 starts:
16:13:00,379 WARN [JMSContainerInvoker] Could not find the topic destination-jndi-name=topic/RssTopic
The JBoss Console entries are like:
jndiName=local/RssMessageBean@12974590,plugin=pool,service=EJB
jndiName=local/RssMessageBean@12974590,service=EJB
Don't know if the MDB is registered correct?
