JNDI API lookup failed: javax.naming.NameNotFoundException: QueueConnectionFactory1

hi,

i m running sun's JMS tutorial,

http://java.sun.com/products/jms/tutorial/1_3_1-fcs/doc/client.html#1

027210. when i do this, i get the following:

C:\Projects\Leader\prototype\jms\PTPClient>java

-Djava.naming.factory.initial=co
m.sun.jndi.fscontext.RefFSContextFactory SimpleQueueSender MyQueue 3
Queue name is MyQueue
JNDI API lookup failed: javax.naming.NameNotFoundException:

QueueConnectionFactory1

i have added MyQueue and QueueConnectionFactory1:

JNDI Name: QueueConnectionFactory1
A unique identifier
Pool Name:QueueConnectionFactory1
Type:javax.jms.QueueConnectionFactory

and MyQueue:
JNDI Name:MyQueue
Required Field Type:javax.jms.Queue

and my class path:
.;%JMQ_HOME%\lib\jndi.jar;C:\Sun\AppServer\lib\install\applications\j

msra\imqjmsra.jar;%J2EE_HOME%\imq\lib\imq.jar;%J2EE_HOME%\lib\j2ee.ja

r;%J2EE_HOME%\lib\locale;C:\Sun\MessageQueue\lib;

i can't figure out what's wrong, most of the people who asked similar

questions online don't use the sun java message queue (JMQ), so their

solutions don't really work for me as they require different jar's

and different setup.

thanks,

sorry, tried that, but got the same error. here is the code, which i got from sun:

and this is the config.bat file for creating the various jms objects:
@echo off

call "%JMQ_HOME%\bin\imqobjmgr" add -t q -l "MyQueue" -j "java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory" -j "java.naming.provider.url=file://C:/temp"

goto end

:noimqhome
echo Please set the JMQ_HOME environment variable.
goto end

Did you try the solutiion in the second link that I provided ?

i figured it out, i manually set the Properties for Context. i believe you can do it using a properties file, but i couldn't get it to work that way, mainly because my program couldn't find com.sun.jndi.fscontext.RefFSContextFactory in the properties file.

import javax.jms.*;
import javax.naming.*;
import java.util.Properties;

public class SimpleQueueSender {
      //Initial context factory
      public static final String CTX_FACT = "com.sun.jndi.fscontext.RefFSContextFactory";

      public static final String PROV_URL = "file:C:\\temp";
      //JNDI name for the queue connection factory
      public static final String QCF_NAME = "QCFactory";
      //JNDI name for the topic connection factory
      public static final String TCF_NAME = "TCFactory";
      //JNDI name for the queue
      public static final String QUEUE_NAME = "myQueue";
      //JNDI name for the topic
      public static final String TOPIC_NAME = "myTopic";

      public static class ExListener
      implements MessageListener
      {
            public void onMessage(Message msg)
            {
                  //done.release();
                  TextMessage message = (TextMessage)msg;
                  try
                  {
