Help with EJB & JNDI

Question

I am getting following error while compiling EJB session client
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
     at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
     at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
     at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
     at javax.naming.InitialContext.lookup(Unknown Source)
     at client.SimpleSessionClient.main(SimpleSessionClient.java:20)
My session client code is
package client;
import java.util.Hashtable;
import beans.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import javax.ejb.*;
import javax.naming.spi.InitialContextFactory;
import javax.naming.NamingException;
public class SimpleSessionClient {
     public static void main(String[] args) {
          try {
               Context jndiContext = new InitialContext();
               Object ref = jndiContext.lookup("ejb/beans.SimpleSession");
               SimpleSessionHome home = (SimpleSessionHome)PortableRemoteObject.
               narrow(ref, SimpleSessionHome.class);
               SimpleSession simpleSession = home.create();
               for (int i=0; i<args.length; i++) {
                    String returnedString = simpleSession.getEchoString(args);
                    System.out.println("Sent String:" + args[i] +", " +
                              "recieved string" + returnedString);
          } catch(Exception e) {
               e.printStackTrace();
I have include j2ee.jar in the classpath too and I could deploy the EJB home and remote interface as well as Bean class in sun application server.
Any help wuld be appreciated.

I am using Sun App server for deploying EJB. In the same system, I am running eclipse where I run the EJB client with JNDI to connect to EJB component.
If this is not the right way, please suggest. I am trying to do this for the first time and completely clueless. I have tried to include different jar files in my classpath and even I am in the process of downloading websphere in case that could help me.
