createQueueSession - causing timeout

spyer Jul 9, 2004 12:15 PM

Trying to create a queuesession to a remote queue, context lookup is acceptable but the createQueueSession is taking a long time and is timing out, can anyone help.

Hashtable env = new Hashtable();
env.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
env.put("java.naming.provider.url", "remote_host:1099");
env.put("java.naming.factory.url.pkgs","org.jboss.naming");
InitialContext ctx = new InitialContext(env);
System.out.println("1 : "+new Date());
QueueConnectionFactory qfc = (QueueConnectionFactory) ctx.lookup("ConnectionFactory");
System.out.println("2 : "+new Date());
QueueConnection queConn = qfc.createQueueConnection();
System.out.println("3 : "+new Date());
Queue que = (Queue) ctx.lookup("queue/ResultsQ4"); // q relevant to session id
System.out.println("4 : "+new Date());
QueueSession session = queConn.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE);
System.out.println("5 : "+new Date());
queConn.start();
System.out.println("6 : "+new Date());

results :

 public Session createSession(boolean transacted, int acknowledgeMode) throws JMSException
 {
 if (closed)
 throw new IllegalStateException("The connection is closed");
 checkClientID();

 if (transacted)
 acknowledgeMode = 0;
 Session session = new SpySession(this, transacted, acknowledgeMode, false);

 //add the new session to the createdSessions list
 synchronized (createdSessions)
 {
 createdSessions.add(session);
 }

 return session;
 }

The checkClientID() is the only part that does any work. It contacts the server to
get the next client id.
If this is taking 20 seconds, your network connection is fscked,
my first guess would be a dodgy DNS server.
