Environment

Operating System: Windows NT/2K
Platform: PC

Description

Platform details:
Weblogic 6.1 sp2, on Windows 2000 (5.00.2195)
Java: Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
      Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode)

Problems details:
I was running my cactus test cases when I experienced the errors shown below.
I was able to reproduce it consistently. It seems to be that whenever the
servlet is initialised and doPost() is called, any action taken afterwards will
result in this error. An example is providing a endXXX(WebResponse wr) method,
and calling wr.getText() within the method. This was one case that triggered
the error.

The problems also seems to occur when re-deploying the application in WebLogic
and not restarting the server.

My code for the test case is as follows:

public class FormConfigurationActionTest extends ServletTestCase {

    ActionServlet _servlet = null;


    public FormConfigurationActionTest(String testName) {
        super(testName);
    }

    public void setUp(){
    }

    public void tearDown() {
        _servlet = null;
    }


    public void beginCreateQuestionFromMenu_Update(WebRequest wRequest) {
        String pathInfo = null;
        String queryString = null;

        // Request variables expected
        wRequest.addParameter("formPrimaryContext",
FormsConfigHelper.CONTEXT_CREATE_EDIT_QUESTION);
        wRequest.addParameter("updateFlag", FormsConfigHelper.ACTION_UPDATE);
        wRequest.addParameter("questionLanguageId", "1");
        wRequest.addParameter("questionType", Question.BOOLEAN_QUESTION);
        wRequest.addParameter("questionDescription", "Is this working
properly?");

        // <form> Action
        wRequest.setURL
("localhost:7001", "/ermtest", "/forms/createeditquestion.do", pathInfo,
queryString);
    }

    public void testCreateQuestionFromMenu_Update() {
        try {
            _servlet = new ActionServlet();
            _servlet.init(config);
            _servlet.doPost(request,response);
        }
        catch (IOException e) {
            e.printStackTrace();
        }
        catch (ServletException e) {
            e.printStackTrace();
        }

// ** AN ACTION HERE CAUSES THE ERROR
     }



    public static Test suite() {
        TestSuite suite = new TestSuite();
        suite.addTest(new FormConfigurationActionTest
("testCreateQuestionFromMenu_Update"));
        return suite;
    }
}
