Exception in program: javax.naming.NoInitialContextException

OK.
 Im using the Glass fish Application server (just in case, setting the variables is related to the application server used)

Thanks for the links.
This modified code by me is attached.
Please check.
Also,  in  NamingEnumeration enum1 = jndi.list(target); what is "target" ?

private void initJMS() throws JMSException 
    {
         try
        {
            //jndi = new InitialContext();
            Hashtable env = new Hashtable();
            env.put(Context.INITIAL_CONTEXT_FACTORY, this);
 
            // Pass the environment to the initial context constructor
            jndi = new InitialContext(env);
 
            // List the objects 
            NamingEnumeration enum1 = jndi.list(target);
            while (enum1.hasMore()) 
            {
                System.out.println(enum1.next());
            }
         }
         
        catch(Exception e)
        {
            JOptionPane.showMessageDialog(null, e);
        }
        try
        {
            ConnectionFactory connectionFactory = (ConnectionFactory)jndi.lookup("jms/ConnectionFactory");
            Queue queue = (Queue)jndi.lookup("jms/Queue");
            connection = connectionFactory.createConnection();        
            session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
            dest=(Destination)queue;
            producer = session.createProducer(dest);
        }
         catch(Exception e)
        {
             System.out.println(e);
            JOptionPane.showMessageDialog(null, e);
        }
    }

I tried out by using:

 Hashtable env = new Hashtable();
            env.put(Context.INITIAL_CONTEXT_FACTORY,this);
            jndi = new InitialContext(env);

Got an Exception : java.lang.ClassCastException: new_jms.QBrowser cannot be cast to java.lang.String

This is the exception after using "com.sun.appserv.naming.S1ASCtxFactory"

javax.naming.NoInitialContextException: Cannot instantiate class: com.sun.appserv.naming.S1ASCtxFactory [Root exception is java.lang.ClassNotFoundException: com.sun.appserv.naming.S1ASCtxFactory]


Now, while running also I get an exception. but Its different:
java.lang.RuntimeException: Cannot Proceed. No Endpoints specified.

OK. I have located the class and added it to library.

now on debugging (F7), i'm getting:

Sep 16, 2008 3:58:36 PM com.sun.appserv.naming.RoundRobinPolicy setClusterInstanceInfo
WARNING: NAM1005 : No Endpoints selected. Please specify using system property com.sun.appserv.iiop.endpoints.
Sep 16, 2008 3:58:36 PM com.sun.appserv.naming.S1ASCtxFactory getInitialContext
SEVERE: NAM1005 : No Endpoints selected. Please specify using system property com.sun.appserv.iiop.endpoints.

java.lang.RuntimeException: Cannot Proceed. No Endpoints specified.

mwvisa1,
Now it works.

The code is:
 Hashtable env = new Hashtable();
            env.put(Context.PROVIDER_URL,"iiop://127.0.0.1:3700");
            env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.appserv.naming.S1ASCtxFactory");

and I had to add some jar files to library.
Got this from one of the links you posted. Thanks a lot for your help.

But one thing im curious to know is , How was it running perfectly before. I had not done any of these settings.

Thanks !

Think because you are running through the debugger.  If the server has the appropriate classes in its classpath already, this probably worked by taking the default path for initial context.  Whenever I had to do this it was always remote to a directory service so I had to implement using naming context in this fashion which is why it came to mind so not necessarily an indication it won't work when you are running productionally again.
