I am going to get the value of the login usename,but seems it always resturn NULL value when click sumbit buttom.

At the login.jsp

String login_user = request.getParameter("txtUID");

Tommy,

I am not sure what you're trying to accomplish. Could you please elaborate a bit more on your end goals. Normally, nobody should be looking/working with the JSP files in Xeams.

By default,xeams only log fail logins with HTTP,i also want to log those success.  Just in case someone guess the right password.

At the new version,there is Admin Access Control,i think it is good enough to limit the IP access.
