Getting WebSphere's MBeanServer thru lookup

[Madhes Rathinam]

I am trying to access the MBeanServer, thru JNDI lookup:

    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.Websphere.naming.WsnInitialContextFactory");
    ctx = new InitialContext(env);

    ctx.lookup("java:comp/env/jmx/runtime");

Its failing with:"javax.naming.NameNotFoundException: Name comp/env/jmx not found in context "java:""
Where as, the similar code works fine in WLS, and returns the MBeanServer instance.

What am I doing wrong?
any pointers?
Thanks in advance

I tried the same using Spring framework too:

                JndiObjectFactoryBean fact = new JndiObjectFactoryBean();
                fact.setJndiName("java:comp/env/jmx/runtime");
                fact.afterPropertiesSet();
                server = (MBeanServer) fact.getObject();

This code works fine in WebLogic, and returns the MBeanServer instance.

Is the JNDI name wrong for WebSphere?
