Hi
Sorry guy!
I have forgotten one thing
in definition part <%! ... %> all implicit JSP Page object are unreachable
so :
1. System.out.println -- You can see it in tomcat window ( if it is not an
system service )
2. You should do this
<%
HttpServletRequest sRequest;
HttpServletResponse sResponse;
HttpSession sSession;
PrintWriter sOut;
sRequest = request;
sResponse = response;
sSession = request.getSession(false);
(
or
sSession = session;
)
sOut = out;
%>
Regards
Valik.
