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

org.jboss.ejb3.proxy.EJBMetaDataImpl to field

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