Hi,

I have configured WebLogic Server 8.1. I logged on to administration console and went to

examples -> services -> JMS -> ConnectionFactories

There are three examples already listed there...

exampleQueue, exampleTopic, exampleTrader

I wrote a jave program to send messages to this exampleQueue. I left the default jndi name - weblogic.examples.jms.QueueConnectionFactory in the weblogic console as such.

my code goes like this...

public static final String JMS_FACTORY = "weblogic.examples.jms.QueueConnectionFactory";
public static final String QUEUE = "exampleQueue";

...
....

created an InitialContext object with
weblogic.jndi.WLInitialContextFactory as the INITIAL_CONTEXT_FACTORY
and
PROVIDER_URL as t3://localhost:7001/

the contect gets created.

then i try to create a QueueConnectionFactory by loking up the context

QueueConnectionFactory qcf = (QueueConnectionFactory) context.lookup(JMS_FACTORY);

this also goes thru

//then i get a QueueConnection, queue session
QueueConnection con = qcf.createQueueConnection();
QueueSession session = con.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);

till this point it works

now, i try to lookup the queue-

try {
System.out.println("Lookup queue");
queue = (Queue) c.lookup(QUEUE);
}
catch (NamingException ne) {
System.out.println("Naming Exception - looking up queue");
try {
queue = session.createQueue(QUEUE);
c.bind(QUEUE, queue);
System.out.println("Bound context to queue");
}
catch (Throwable th) {
th.printStackTrace();
System.out.println("Exception looking up queue: " + th.getMessage());
}
}

HERE's WHERE I GET EXCEPTION

hi,

please ensure, that
- at least one JMS Server is successfully deployed;
- and for this JMS Server you have created at least one JMS Queue (in your case, JNDI name must be "exampleQueue").


greetings,
makiey

Thanks for the reply.

I figured out the problem.

The queue name should be a fully qualified name...

QUEUE = "weblogic.examples.jms.exampleQueue";

I ran my test program and looks like the messages are sent to the queue.

I also see the messages in my queue in the Weblogic Server Console

Thanks
