WLST in embedded mode

Question

Hi,
I am trying to implement wlst in embedded mode to automate few setup creations in weblogic administration server.I have added the required jars in class path and tried to run the code.But the WLSTInterprester failed to instantiate and threw below excpetion:
Exception in thread "main" java.lang.NullPointerException
  at java.io.File.<init>(Unknown Source)
  at weblogic.management.utils.PDevHelper.getUpgradeLaunchLocation(PDevHelper.java:77)
  at weblogic.management.utils.PDevHelper.getPDevClassLoader(PDevHelper.java:36)
  at weblogic.management.scripting.utils.WLSTUtil.setupOffline(WLSTUtil.java:226)
  at weblogic.management.scripting.utils.WLSTInterpreter.<init>(WLSTInterpreter.java:134)
  at weblogic.management.scripting.utils.WLSTInterpreter.<init>(WLSTInterpreter.java:76)
  at com.ncr.main.EmbeddedWLST.<init>(EmbeddedWLST.java:11)
  at com.ncr.main.EmbeddedWLST.main(EmbeddedWLST.java:27)
Please help me  in resolving this issue.
Thanks in advance

Think I've figured it out, you must define weblogic.home to point to an valid home. I was using JDeveloper 11.1.1.6 to extract the jars from, but for a quick test pointed to a 11.1.1.7 WLS home and it worked. This got me past the NullPointerException,  I just kept adding jars to fix the ClassDefNotFound exceptions till it ran clean; so this is the minimal set that ran my script
This is my java command line (obviously broken down for readability).
java -cp
./bin:
./lib:
./lib/jython.jar:
./lib/wlfullclient.jar:
./lib/com.oracle.cie.comdev_6.3.0.0.jar:
./lib/com.oracle.cie.config-wls_7.1.0.0.jar:

This was the output

This is my embedded WLST class (hacked from an example I found via the Google Institute Of Technology)
package com.testing.wlst;
import java.util.*;
import weblogic.management.scripting.utils.WLSTInterpreter;
import org.python.util.InteractiveInterpreter;
public class WLST
   static InteractiveInterpreter interpreter = new WLSTInterpreter();
   private static void connect()
      StringBuffer buffer = new StringBuffer();
      buffer.append("connect('weblogic','NoneOfYourBiz','t3://el01cn06:7599')");
      interpreter.exec(buffer.toString());
   private static void status()
      StringBuffer buffer = new StringBuffer();
      buffer.append("state('web-cluster','Cluster')");
      interpreter.exec(buffer.toString());
   public static void main(String[] args)
      connect();
      status();
