  Pedro,
               Greetings!! Now i have got some idea about the 
ServletTestCase.Please clirify the following.

  My MyServletTestCase  looks like:::

  package com.test;

  import javax.servlet.ServletException;
  import junit.framework.Test;
  import org.apache.cactus.ServletTestCase;
  import org.apache.cactus.WebRequest;
  import org.apache.cactus.WebResponse;


  public class MyServletTestCase  extends ServletTestCase {
   
   private TestServlet ts=null;
    

    public TestServletCase(){
     
     super();
     
     System.out.println("Inside the TestServletCase");
    }
    public TestServletCase(String name){
     super(name);
    }
    public TestServletCase(String name,Test t){ 
     super(name,t);
    }

    protected void setUp(){
     ts=new TestServlet();
     try{
        ts.init(this.config);
     }catch(ServletException se){
      System.out.println("Inside the Servletexception se");
      se.printStackTrace ();
     }
    }

    public void begin(WebRequest request){
     request.addParameter("txtName","Nagaraj"[Pedro Nevado] 
,WebRequest.POST_METHOD  );
    }

    public void testValidSearch(){
     System.err.println("Inside the testValidSearch");
     invokePost();
    }
    public void endValidSearch(WebResponse response){
     assertTrue((response.getText().indexOf("Error:")<0) && 
       (response.getText().indexOf("Search results") >=0 ));
     
    }
    protected void tearDown(){
     ts.destroy();
    }
    
    private void invokePost(){
     try{
      
      
       ts.doPost(this.request, this.response);
     }catch(Exception ex){
      ex.printStackTrace();
     }
    }
  }


  The Actual servlet looks like::::


  package com.test;

  import javax.servlet.ServletConfig;
  import javax.servlet.ServletException;
  import javax.servlet.http.HttpServlet;
  import javax.servlet.http.HttpServletRequest;
  import javax.servlet.http.HttpServletResponse ;
  import java.io.IOException;
  import javax.servlet.RequestDispatcher;

  public class TestServlet extends HttpServlet{
   
   public void init(ServletConfig config) throws ServletException{
    super.init(config);
   }
   
   public void doPost(HttpServletRequest req,HttpServletResponse res) throws 
     IOException,ServletException{
    System.out.println("Inside the doPost Method");
    String str=req.getParameter("txtName");
    req.setAttribute ("NAME",str);
    System.err.print("str::::"+str);
    //getServletContext().getRequestDispatcher("/jsp/Results.jsp").forward(req, 
res);
    
   }

  }


  My Client class looks like::::

  class ClientTest{
  public static void main(String args[]){
  TestServletCase ts=new TestServletCase();
   ts.testValidSearch();
  }
  }

  My web.xml looks like:::
  <?xml version="1.0" encoding="UTF-8"?>
  <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee 
" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

   </servlet>

   </servlet-mapping>
   <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file> 
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
   </welcome-file-list>
  </web-app> 



  I am getting the Null pointer Exception in doPost() method of TestServlet  
class(Marked in Red color).It says the incoming request is null.Could you 
please help me i am doing the mistake??
  Then how to invoke the actual test case?? if i will put System.out.println() 
in the testSetUp(),begin() method , it is not executed. please help me resolve 
this one?

  Thank you
