I have 2 jboss servers: serverA and serverB. On serverA, I have a SLSB beanA.
This SLSB has to call some method of SLSB beanB deployed on serverB.
I can successfully lookup beanB from beanA, and do my business. But, when I
restart serverB, I cannot lookup beanB again from beanA.
The code segment in beanA that re-lookup beanB is:
| try
| {
| env = new Hashtable();
| env.put(Context.PROVIDER_URL, serverUrl);
| env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| env.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
| Context ctx = new InitialContext(env);
| Object ref = ctx.lookup(beanBJndiName);
| if (ref == null)
| System.out.println("Got ref object");
| else
| System.out.println("ref is null");
| Object curHome = PortableRemoteObject.narrow(ref, homeClass);
| }
| catch (Exception ex)
| {
| ex.printStackTrace();
| }
|
and here is what I got on serverA's screen
