Re: [Wrapper-user] Detect user login

[Catalin K. <cat...@ya...>]

Thanks for your comments Leif, i'll use a thread then :), no problem. 
  
  Regarding this, it's clear that i need to use integration method 3, and  i have to override start/stop and controlEvent methods of the  WrapperSimpleApp class, and reuse as much other code as possible,  because i need to run JBoss as service and show an icon on the tray bar  when is running.
  
  The problem is that there is now way to extend, for ex, the  WrapperSimpleApp class and reuse code as much as possible, i need to  copy the source as it is in my custom WrapperSimpleApp that will also  contain code to manage the tray icon. Is this right? it looks like i  would realy use another  listener interface that is notified for  the main usable events without beeing involved in running the wrapped  app....is it possible to consider providing such an interface and  events?
  
  Regards,
  Catalin

    The problem is that Windows does not provide an easy way to do 
this.  When a user
logs out, the OS will send a "user logged out" signal to all running 
processes.  The
Wrapper traps that and reports it.   This is done because most 
applications want to shut
down when the user logs out.   There is no such signal when a user logs in.

    Starting with version 3.1.1, you can call WrapperManager.getUser or
WrapperManager.getInteractiveUser to find out who is logged in at any given
time.  This is operation does require a bit of processing as it is done 
by scanning
the registry.  You would have a daemon process that would call it ever 
10 seconds
or so, then stop once a logged in user was found.  The loop could then 
be restarted
if the logged out signal is detected.
    The feature was actually added in version 3.1.0, but there was a 
memory leak in
the call.
    Due to a couple other bugs however, I would suggest using 3.1.2.  
That version
is very stable.

Cheers,
Leif
