Hi Experts,
Im using jboss-4.0.4.GA and trying to lookup for ejb from the web client.It throws exception while doing a look up for the remote service.
I have run the patch also.
The same remote is looked up properly in the jboss-4.0.4.CR2 
Here's the exception

---------------------------------------------------------
The lookup code is:
Hashtable environment = new Hashtable();
		environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
		environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
		environment.put(Context.PROVIDER_URL, "jnp://localhost:1099"); // remote machine IP
		InitialContext context = new InitialContext(environment);
		requirementService = (RequirementService)context.lookup("/RequirementServiceImpl/remote"); //ejb-name
    	System.out.println("-->> lookup object successfully");
	}
	catch (NamingException e)
	{
		e.getMessage();
		e.getCause();
	e.printStackTrace();
	}
	catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}

-------------------------------------------------------

Can any one suggest me as to what must be the possible reason and what is the solution for it.

Thanks
Ved
