Tomcat Manager session list "Gussed user name"

[Jacob Rhoden <ja...@rhoden.id.au>]

Hi,

I have recently discovered the tomcat manager can not only show a list 
of sessions, but the "Gussed username" for that session. This is very 
handy except it seems to read a session variable called "user" and just 
displays it. Our session object called "user" is a class not a string, 
show it displays things like "User@e37db8".

How do people manage this, do they implement a toString() to handle 
display of the user, or is there another way to teach the manager 
application the session name? (I am trying to find this in the source 
code but am only up to this so far:

------------------------------
public static String guessDisplayUserFromSession(Session in_session) {
    Object user = SessionUtils.guessUserFromSession(in_session);
    return escapeXml(user);
}
-------------------------------


Thanks,
Jacob

I am now going to answer my own question because digging through the 
source code got the answer quicker (: Tomcat searches the session for an 
object of type Principal, and uses the .toString() method to read the 
username. So if you have a session object called "user", make it extend 
"Principal" and add a toString() method so it displays user information 
in a nice format.

Happy session management! (:

Best Regards,
Jacob
