can someone tell me or direct me to a url where the usage of "forward" is
explained because i can't get it to work. i keep getting :
java.lang.IllegalStateException: Cannot forward when getOutputStream()
already called.
mycode:
<java>
String url="welcome.jsp";
ServletContext context=getServletContext();
RequestDispatcher rd=context.getRequestDispatcher(url);
HttpServletResponse hsr=Response.getServletResponse();
rd.forward((ServletRequest)Request,hsr);
</java>
thanks
fabrice
