Login hook/ log off hook

[hexaplus]

I'm working on a project and I need to send a message at login and logoff of a users. However the tricky part is that I need to run the server while there are no clients logged on to the system.

So I would like to run that application as a service, but I need to catch the logon log, off hook, for each user that logs on to the machine. Any info for Windows or Mac would be great.

Thanks, mike

Any sugestions on where to look?

Need a bit more details.

Is your main application J2EE based?

If it is a J2EE based app on a server which supports JMX, you can write a service which continuously polls your file system for any logging info.

Thanks! I'll look into it.
