[HELP] Trying to use SoapUI JAR to make changes

Ok, I have figured it out. If anybody wants the code here it is. After looking at the javadoc and Type Hierarchy in Eclipse I found out that there is a class WsdlTestRequestStep which provides some good helper methods. Here is my code:

import java.io.IOException;

import org.apache.xmlbeans.XmlException;

import com.eviware.soapui.impl.wsdl.WsdlProjectPro;
import com.eviware.soapui.impl.wsdl.testcase.WsdlTestCase;

import com.eviware.soapui.impl.wsdl.teststeps.WsdlTestStep;
import com.eviware.soapui.model.testsuite.TestAssertion;
import com.eviware.soapui.model.testsuite.TestCase;
import com.eviware.soapui.model.testsuite.TestProperty;
import com.eviware.soapui.model.testsuite.TestStep;
import com.eviware.soapui.model.testsuite.TestSuite;
import com.eviware.soapui.support.SoapUIException;

/**

 */
public class AutoProject {
 private String projectFile;
 private WsdlProjectPro project;
 
 /**
  * Constructs object to prepare for modifying the file.
  * @param projectFile Location of the project file
  */
 public AutoProject(String projectFile) {
  this.projectFile = projectFile;
  openProject();
 }
 
 /**
  * Performs the actions against the file
  */
 public void run() {
  for (TestSuite testSuite : project.getTestSuiteList()) {
   for (TestCase testCase : testSuite.getTestCaseList()) {
    //remove any autos that have been added
    cleanAutos((WsdlTestCase) testCase);
    for (TestStep testStep : testCase.getTestStepList()) {
     String name = testStep.getName();
     //look for the test step to clone
     if (name.endsWith("-correct")) {
      generateAutos((WsdlTestStep)testStep);
     }
    }
   }
  }
 }

 /**

  */

  try {
   project.save();
  } catch (IOException e) {

 }

   WsdlTestStep wsdlTestStep = (WsdlTestStep) testStep;
   String name = wsdlTestStep.getName();
   if (name.endsWith("(auto)")) {
    testCase.removeTestStep(wsdlTestStep);
   }
  }
 }
 
 /**

  String newName = correctName.substring(0, correctName.length()-"-correct".length());
  return correctStep.clone(correctStep.getTestCase(), newName + "-" + name + "(auto)");
