Cactus and HttpUnit

[Barbara Allori]

Hi,
I'm try to testing my jsp using cactus end httpUnit.
I write test like this:

public class testClass extends ServletTestCase {
        .....
        public void testTest1() throws ServletException, IOException {
     ....
        bean bean = new bean();
        bean.setRuoloUtente(entitaRuolo);
        session.setAttribute("xyz",bean);
        RequestDispatcher rd 
= 
config.getServletContext().getRequestDispatcher("/jsp/test.jsp");
        rd.include(request,response);

        }
        public void endTest1(WebResponse response) {
        assertEquals("OK",response.getResponseMessage());
        try {
        WebForm form = response.getFormWithName("Form");
        ....
        } catch (SAXException e) {
                ....
        }
        }
}
and when I run it, I catch this exception:

java.lang.NullPointerException

I use:

cactus 1.4.1
httpunit 1.5.4
junit 3.8.1
This is my classpath:

SET CLASSPATH=%CLASSPATH%;%HTTP_UNIT%\lib\httpunit.jar
SET CLASSPATH=%CLASSPATH%;%HTTP_UNIT%\jars\nekohtml.jar

SET CLASSPATH=%CLASSPATH%;%JAVA_HOME%\lib\cactus-1.4.1.jar

Where I wrong? Can anyone help me?
