URL address

My application has a Login.jsp page with a form action="/authenticator/Login".

The following servlet java code will forword the page to the next page "Disclaimer.jsp". But the URL address in the next page is "http://csctestserver/authenticator/Login".

RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(targetURL);
dispatcher.forward(request, response);

I want a solution to make the URL address as "http://csctestserver/Disclaimer.jsp".

Thanks!

encodedURL is a StringBuffer not a String... either way you can use this as well:

String encodedURL = targetURL;

 if (!isFirst) {
     encodedURL += "&"
 } else {
     encodedURL += "?"
  }

  encodedURL += strParam + "=" + request.getParameter(strParam);

response.sendRedirect(response.encodeURL(encodedURL));

Use the ora:redirect tag from http://www.thejspbook.com/jspbook.zip

I would preciate it if you can also tell me how to set up your example code to run. I have VAJ 3.5.3 installed on my windows 2000 machine.

if you downloaded the zip objects posted above:

it's in src/com/ora/jsp/tags/generic

all it does is reads in all parameters passed in, attaches them to your target url and does a sendredirect.

I'm not sure the solution. Can you give me the code and tell me where I should add it?

do you know how to use tag libraries?

bobbit31Commented:
anyway, this is basically what it does:

Enumeration enu = request.getParameterNames();
StringBuffer encodedURL = new StringBuffer("http://csctestserver/Disclaimer.jsp");          
String strParam;

boolean isFirst = true;

while (enu.hasMoreElements()) {
     strParam = (String) enu.nextElement();

    if (!isFirst) {
       encodedURL.append('&');
     } else {
       encodedURL.append('?');
    }
   
    encodedURL.append(strParam.append("=").append(request.getParameter(strParam)));
    isFirst = false;
}

response.sendRedirect(response.encodeURL(encodedURL.toString()));

I know html/xml tag. I'm not sure what you mean. I'm new to Java.

instead of using the ora:redirect tag, you can use the code above to achieve more or less the same thing.

Just in order to make my orignal question more in detail:

Login.jsp page has one "Login" button. It displays the same login page with an error message if the user enters invaild userId/password. Otherwise, it displays the Disclaimer page.

Here is a piece of java code:

RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(targetURL);
dispatcher.forward(request, response);

The request object has the same URL path for both login successful or fail:"http://csctestserver/authenticator/Login"


Question for you:
Where should the code go?Login.jsp,Disclaimer.jsp, or replace my java code shown above?

I tried to run the code, but got an error "The method append invoked for type java.lang.String with arguments(java.lang.String) is not defined." on the following code:
encodedURL.append(strParam.append("=").append(request.getParameter(strParam)))
