Hi,all
   I have some problem to simulate the browser when I use httpclient of apache,or httpunit.
   The thing is there r 2 urls in the server(based on Notes)
   the first url is http://132.159.173.27/dept1/public/homepage.nsf/HomePage?OpenForm,
   the second url is http://132.159.173.27/dept1/public/sign_in.nsf?OpenDatabase,
the visitor will not visit the 2nd url if he doesn`t log in the system through the 1st url.
when I try to simulate the browser by httpclient.
here is my code:
     String url ="http://132.159.173.27/dept1/public/homepage.nsf/HomePage?OpenForm";//the 1st url
    HttpClient client = new HttpClient();
    PostMethod postMethod = new PostMethod(url);
    client.setConnectionTimeout(800);
    postMethod.addParameter("%%ModDate","0000000000000000");
    postMethod.addParameter("Username",userName);
    postMethod.addParameter("Password",password);
    postMethod.addParameter("RedirectTo","/dept1/public/homepage.nsf/HomePage?OpenForm");
    int statusCode1 = client.executeMethod(postMethod);
    System.out.println("statusCode1="+statusCode1);
    url="http://132.159.173.27/dept1/public/sign_in.nsf?OpenDatabase";//the 2nd url
    //HttpMethod method = new GetMethod(url);
    postMethod = new PostMethod(url);
    int statusCode = client.executeMethod(postMethod);
    System.out.println("statusCode="+statusCode);
    System.out.println(postMethod.getResponseBodyAsString());
    //method.releaseConnection();
    //System.out.println("statusLine>>>" + postMethod.getStatusLine());
    postMethod.releaseConnection();

When I run these codes,the first step I will log in the system,but when I try to visit url2 through httpclient,the
response will resend to the 1st url to login automatically,
so What is the reason?? thx.


When I try to use httpunit,insted of httpclient,the thing will be different.
here is my code:
FormLogin login = new FormLogin("login");
    String username = login.getUserName();
    String password = login.getPassword();
    WebConversation webConversation = new WebConversation();
    try {
      WebResponse response = webConversation.getResponse(
          "http://132.159.173.27/dept1/public/homepage.nsf/HomePage?OpenForm");//the first url
      //get the form to login,and u can change it depends on the real system
      //to simulate the form of oa login system
      WebForm form = response.getForms()[0];
      //WebForm form = response.getFormWithName("_DominoForm");
      form.setParameter("Username", username);
      form.setParameter("Password", password);
      form.setParameter("%%ModDate", "0000000000000000");
      form.setParameter("RedirectTo",
                        "/dept1/public/homepage.nsf/HomePage?OpenForm");
      //submit the form request
      response = form.submit();
      WebLink[] link = response.getLinks();
      int j = 0;
      for (int i = 0; i < link.length; i++) {
        if (link[i].getURLString().equalsIgnoreCase(
            "../../public/sign_in.nsf?OpenDatabase"))
          j = i;
      }
      //response = webConversation.getResponse("http://132.159.173.27/dept1/public/sign_in.nsf/_k2f7t84uano9rrs8jp3ah7i5b2epbu_?OpenForm");// the second url
      //System.out.print(link[j].getURLString());
      response = link[j].click();
      // System.out.println(response.getContentType());
      // System.out.println(response.getText());
    }
    catch (Exception e) {
      e.printStackTrace();
    }

when the program run to "response = link[j].click();"
and the exception will be thrown,just like this:
TypeError: getElementsByTagName is not a function. (httpunit; line 36)

Can anyone to help me??
Thanks very much.

I can't see your pages (timeout), but i've never been able to use httpunit on any page that uses a significant amount of JavaScript. If you can avoid executing the javascript, go for it... (your errors come from the js)
