I would recommend using Java Messages (JMS). One of the benefits of
JMS is
that if you decide to move your instances to different machines,
things will
still work. You can use OpenJMS and the code from WOProject. You don't
need
to make any major changes to your project either.
Besides JMS which would fit your needs in your simple case you could
create a DirectAction:
public WOActionResults removeSessionAction() {
String passwd = request().stringFormValueForKey("password");
String sid = request().stringFormValueForKey("sid");
if (!passwd.equals(aPredefinedPassword)) {
return null;
} else {
WOApplication.application().sessionStore().removeSessionWithID(sid);
}
}
you can call this direct action with an URL like:
http://yourServer/cgi-bin/WebObjects/Appname.woa/wa/removeSession?
password=secred&sid=theIdFromTheSessionToRemove
Of course, you would call this method on ever particular instance.

I have seen this asked before, but now I cannot find it ... How do I
send a message from one instance to other instances of my WO app?
(Without using the database.)
From within one instance, I need to invoke an application-level method
in all instances. If it's complicated, please explain it a bit.
In a nutshell, this is the invocation:
this.application().sessionStore().removeSessionWithID(...);
Thank you,
Nathan
