How to run openscript from Java?

Question

Hi!
I have recorded a web script using OpenScript. But instead of doing the playback in the OpenScript environment, I want to run the script from regular Java code.
Does anyone know how to do that?
Basically what I have tried out, is copying the code from the Java code view in Openscript, into a class in my Java project and imported all the oracle.oats... jar-files into my build path. It compiles fine.
Then I try to call;
MyOpenscriptClassInstance.initialize();
MyOpenscriptClassInstance.run();
MyOpenscriptClassInstance.finish();
The initialize fails on a NullPointer on the browser.launch(), so clearly some more setup is needed to get the script running.
I found one useful tip here How to call openscript from a flat java file about an alternative method, but I do not have oracle.oats.jagent.applications.qos among my jar-files in C:\OracleATS\openscript\plugins, so I am not able to locate the JavaAgentWrapper-class, the ScriptResult-class and the RunParameters-class.
If anyone could guide me in the right direction, I would be grateful.
I am running OpenScript version 9.2.0.0 by the way.

Hi again!
I found theoracle.oats.jagent.applications.qos jarr file now, so I feel like I am getting closer. I also set up log4j (hopefully correct using this guideline: http://snippets.dzone.com/posts/show/3248).
However, the execution fails with this error message:
*[2011-02-09 14:43:45,960]ERROR 0[Thread-2] - oracle.oats.jagent.applications.qos.JavaAgentWrapper.run(JavaAgentWrapper.java:82) - runScript.bat can't be found at null\runScript.bat*
There are errors when running the script.
My code looks like this:
package guiDriver;
import oracle.oats.jagent.applications.qos.JavaAgentWrapper;
import oracle.oats.jagent.applications.qos.RunParameters;
import oracle.oats.jagent.applications.qos.ScriptResult;
public class OpenScriptWrapper {
     private String m_jwgFile;
     private JavaAgentWrapper m_qos;
     private ScriptResult m_result;
     private RunParameters m_param;
     private static final String RESULT_FOLDER = "C:\\OracleATS\\OFT\\DatabaseChangeTest\\results";
     // the JavaAgent playback process is supposed to finish
     // within this duration specified by users.
     private static final long JAGENT_TIMEOUT = 90000L;
     public OpenScriptWrapper() {
          m_qos = new JavaAgentWrapper();
          m_jwgFile = getJWGFile();
          m_param = new RunParameters();
          m_param.setScriptJWGFile(m_jwgFile);
          m_param.setResultFolder(RESULT_FOLDER);
     private String getJWGFile() {
          return "C:\\OracleATS\\OFT\\DatabaseChangeTest\\DatabaseChangeTest.jwg";
     public void runJAWrapperWithTimeout() {
          m_result = m_qos.run(m_param, JAGENT_TIMEOUT);
          if (m_result == null) {
               System.out.println("There are errors when running the script.");
               return;
          System.out.println("Overall Result: " + m_result.getOverallResult());
          System.out.println("Overall Duration: " + m_result.getOverallDuration()
                    + "ms");
          System.out
                    .println("Result Report File: " + m_result.getCsvReportFile());
     public static void main(String[] args) {
          OpenScriptWrapper jaws = new OpenScriptWrapper();
          jaws.runJAWrapperWithTimeout();
Tips anyone?
