Someone else reported the problem already. You are calling a method in a
bean but the response is never set in the bean, therefore when you access
your RES variable, its null. Also, why do you want to set a cookie? Every
engine does this for you automatically unless you have a .92 JSP engine or
earlier. Sessions are automatically handled for you, so there is never a
need to set a cookie with "session_id". FYI, "jsessionid" is the Standard
cookie name to be used to make your application work across
vendors..starting in Servlet 2.2. Don't worry about sessions. What vendor
are you using (name/version)? I am pretty sure it will do automatic session
cookie handling for you.
