Find the name of your session bean in JBoss

If you are writing JEE applications, you will most likely write a Session Bean to provide your View Tier with the services it need. This Session Bean is reached by the client application through a service called JNDI.

The problem is that each Application Server uses a different JNDI provider and this makes portability very hard to achieve. I wrote the code below to allow me to access the JNDI service and find my Session Bean. Please note that this would be much better placed in the container configuration file and not in the code, as it is here.

protected static Context getInitialContext( ) throws javax.naming.NamingException {
  Properties p = new Properties( );
  p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
  p.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
  p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
  return new javax.naming.InitialContext(p);
}


This method will return a java.naming.Context object which can be used for the lookup on the service, like this:


PatientServices patientServices = (PatientServices)jndiContext.lookup("PatientBean/remote");


And how can you find the name under which your bean has been published on the application server? Well, in JBoss all you need to do is access the jmx-console (default URL is http://localhost:8080/jmx-console/). On the jboss session from this page, find the JNDIView service. Click on it and a new page will display on your browser.
On this new page there will be a java.lang.String list() MBean operation, and clicking on the invoke button the names of all available JNDI names will be shown on a tree-like structure which composes the name under which your Session Bean is registered on the JNDI service.
