Need Help: How to get rid the NoInitialContextException

Question

import javax.naming.*;
import java.io.*;
import java.util.*;
public class test {
public static void main(String[] args) throws Exception{
Context ctx = new InitialContext();
Hashtable env = ctx.getEnvironment();
System.out.println(env.toString());
I'n trying to printout the environment contained in the initial context but it just keeps giving me the NoInitialContextException during runtime. Below are the version of j2se and classpath i have set.
J2SE version: J2SDK 1.3.1_03
Classpath: %JAVA_HOME%/lib
OS: WIN2K
My Knowledge on JNDI: ROOKIE (Beginner)
Please help out.

tehts,
You must set the environment first:
import java.util.Hashtable;
import javax.naming.*;
import javax.naming.directory.*;
env = new Hashtable(5, 0.75f);
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, URL);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, DN); //use your own one
env.put(Context.SECURITY_CREDENTIALS, PassWord); //use your own one
try {
ctx = new InitialDirContext(env);
Hashtable env1 = ctx.getEnvironment();
System.out.println(env1.toString());
} catch (NamingException e) {
e.printStackTrace();
Hope this helps.
Cheers,
George
