Advice Client Problem

[Vijay Gade]

Hi,

I know this is a question that has been asked very frequently, but I could not get it to work.

This is basically about the jndi set up in the AdviceClient.java.

This is what I did:

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put (Context.PROVIDER_URL, "iiop://localhost:3700");
 
Context initial = new InitialContext(env); //This part runs well
 
Object objref = initial.lookup("AdviceBean"); //This part runs well too
 
AdviceHome home = (AdviceHome) PortableRemoteObject.narrow (objref, AdviceHome.class); //And so does this part
 
//Now, if I run the home.create(), that's when I end up getting a null pointer exception. And following is the check, that returns true for home==null. Can anybody help me in this one please?
if (home == null) {
    System.out.println ("home pointing to null object");
}
 

Thanks,
-Vijay

Vijay,
I guess some thing may wrong in the Initial context look-up.
Here what you did
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put (Context.PROVIDER_URL, "iiop://localhost:3700");

please look for the port number 3700 is correct? did you use default port while creating your domain? or did you mention 3700?

usually default would be 7001 ..so try with that if you want to..

In WebLogic
JNDI_FACTORY= "weblogic.jndi.WLInitialContextFactory";
url = "t3://localhost:7001";
env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY);
env.put(Context.PROVIDER_URL, url);


and one more thing is ..if you are client also running on the same box, then you can use default way also

lets say

Context jndiContext = null;

try
{

jndiContext = new InitialContext();

Object o = jndiContext.lookup("AdviceBean");
AdviceHome home = (AdviceHome)PortableRemoteObject.narrow (o, AdviceHome.class);
Advice = AdviceHome.create();

try this ...


Thanks,

I am positive about the iiop port. I went to the Application Server's General Tab in the admin gui, and that was where I found that 3700 was the port.
Basically, I am using J2EE 1.4 and SDK 1.5. Can that be any reason?

Vijay,
"I am using J2EE 1.4 and SDK 1.5. Can that be any reason?"
I don't think this causing anything there.
Basically, you are client not able to get/locate the home stub from the server/container.

Did you try using the default Context that I showed you?
