Context Lookup Failing

[A Shar]

I am working on a pretty simple program using JBuilder and WebLogic. I have depolyed a simple cart JAR to WebLogic 8.1. Then wrote a test client to test the EJB.
The JAR has deployed fine, and I can test the Cart JNDI name successfuly on WebLogic.
But when I run the test client program it fails when it tries to do a context lookup on the Cart.
Object ref = context.lookup("Cart");
The Cart is actively deployed.
Any suggestion on how to fix this problem?
Test Client code snippet: =====================================

public void initialize() {
try {
//get naming context
System.out.println("I am here1\n" );
Context context = new InitialContext();
if (context != null) {
System.out.println("I am here2\n" );
}
//look up jndi name
Object ref = context.lookup("Cart");
if (ref == null) {
System.out.println("I am here3\n" );
}
//look up jndi name and cast to Home interface
cartHome = (CartHome) PortableRemoteObject.narrow(ref, CartHome.class);
}
catch(Exception e) {
e.printStackTrace();
}
}
End Code Snippet=========================================================

Thanks for your help!

The problem is that outside of the container, you need to configure the InitialContext instead of just saying new InitialContext(). Take a look at this for the correct configuration for WLS8.1.

Lasse, Thanks for your reply. I tried to set up the context using the code from the link you provided. Still, it isn't working. I do get a ontext, but the code fails when it tries to do a lookup on cart. The error is the same. Here is the new code:
New Code========================
package cart_session;
import javax.naming.*;
import javax.rmi.PortableRemoteObject;
import java.util.*;
public class CartTestClient1 extends Object {
private CartHome cartHome = null;
//Construct the EJB test client
public CartTestClient1() {
System.out.println("I am here\n" );
initialize();
}
public void initialize() {
try {
//get naming context
System.out.println("I am here1\n" );
Context ctx = null;
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL, "t3://localhost:7001");
try {
ctx = new InitialContext(ht);
// Use the context in your program
}
catch (NamingException e) {
// a failure occurred
}
finally {
try {ctx.close();}
catch (Exception e) {
// a failure occurred
}
}
//Context context = new InitialContext();
if (ctx != null) {
System.out.println("I am here2\n" );
}
//look up jndi name
Object ref = ctx.lookup("Cart"); //Code fails here//
if (ref == null) {
System.out.println("I am here3\n" );
}
End new code ====================================================
Thanks for your help!

Have you used a real JNDI name or an ejb-ref? It would help if you'd post the ejb-jar.xml and weblogic-ejb-jar.xml deployment descriptors (only those parts relevant to the "Cart" bean, please).
By the way, "Electron Proton" fails the obviously-fake test of our naming policy so you'll need to change that into something real-looking.

Here is the weblogic-ejb-jar.xml

I converted the context object to string and this is what I get:
javax.naming.InitialContext@19b04e2 -- Eventhough the exception says
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
