Hi,
My intranet application was working fine on tomcat 3.2 but when i try to upgrade to 4.1.24 it goes wrong with the code. Here is my example.
I have a loginaction.java which has following code
...
Cookie cookie =  createCookie(request, "userId", userId);
response.setHeader("realm","../user/login.jsp");
response.sendRedirect("../user/login.jsp");
...
In my jsp i have something like:
...
<%
    String userId=null;
    Cookie[] cook = request.getCookies();
    if( cook!= null){
     for (int k=0; k<cook.length ; k++){          
          if(cook[k].getName().equals("userId"))
               userId= cook[k].getValue();              
               }
            }
     if(userId==null){
     response.setHeader("Back","..");
     response.sendRedirect("..");
     return;          
     }
...

My problem is that the redirect always occurs... in other words the cookies are not set... but it used to work in 3.2?
Any Idea?

Thanks!

>  createCookie(request, "userId", userId);

where is this method from?

I thought you had to do:

response.addCookie( new Cookie( "userId", userId ) ) ;

So your loginAction.java code you posted becomes:

Cookie cookie = new Cookie( "userId", userId ) ;
response.addCookie( cookie ) ;
response.setHeader("realm","../user/login.jsp");
response.sendRedirect("../user/login.jsp");

>> My problem is that the redirect always occurs

Which redirect?  The one in the JSP (I'm guessing) or the one in loginaction.java (presumably a servlet)?

Is the loginaction servlet definitely being called (in turn redirecting to the login.jsp)?

As Tim asks, what is the code for the createCookie() method?

Are you calling the setMaxAge() method anywhere?

Does this all happen in a single session (the default lifetime of a cookie), or is the problem occurring when a user later goes directly to the login.jsp page?
