Looking up JNDI in Weblogic 5.1.0 server

Question

I have written a simple stateless session bean in weblogic 5 server.
The bean has been deployed etc.
I am having problems in accessing it from the client.
My client code is as under: Its giving an exception in getting the initail context in the line->
properties.put("java.naming.factory.initial", "weblogic.jndi.WLInitialContextFactory");
Should the username be system and the password be the same which i had entered while installing weblogic server??
Pls help asap.

My Program source is:
import java.io.*;
import javax.naming.*;
import javax.naming.InitialContext;
import java.util.Properties;
import javax.ejb.*;
import java.rmi.*;
public class HelloClient {
     public static void main(String[] args) throws Exception {
          System.out.println("\nBegin Client...\n");
          try {
     System.out.println("\n Start to call func...\n");
     Context ctx = getInitialContext();
System.out.println("\n Returned func...\n");
     HelloHome home = (HelloHome)ctx.lookup("HelloHome");
     System.out.println("\n After ctx.lookup...\n");
     System.out.println("Creating Hello\n");
     Hello hello = home.create();
System.out.println("The result is "+ hello.hello());
catch (Exception e) {
System.out.println(" => Error <=");
e.printStackTrace();
System.out.println("\nEnd HelloClient...\n");
static String user = null;
static String password = null;
static String url = "t3://localhost:7001";
static public Context getInitialContext()
throws Exception {
     System.out.println("Inside getInitialContext");
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, url);
if (user != null) {
System.out.println ("user: " + user);
p.put(Context.SECURITY_PRINCIPAL, user);
if (password == null)
password = "";
p.put(Context.SECURITY_CREDENTIALS, password);
System.out.println("Finished getInitialContext");
     return new InitialContext(p);
The error when i run HelloClient is:
Begin Client...
Start to call func...
Inside getInitialContext
Finished getInitialContext
=> Error <=

End HelloClient...
I feel that there is some error in setting the classpath or the path--->>
my classpath is:
c:\java\jre\lib\rt.jar;c:\weblogic\lib\weblogicaux.jar;c:\java\lib\classes.zip;.;c:\weblogic\classes\hello.jar
and my Path is:
c:\weblogic\bin;c:\java\bin
Please Help out ASAP.....
Thanks in advance
