We have a situation where we Single
Sign On with a 3rd party system. When the user SSO's into our system,
we need to keep their session alive in that 3rd party system for when
the user re-enters that system. We do this by having a set of
TimerTask's firing every X minutes. The idea is that if we detect that
the user's session in the 3rd party system is no longer valid, we have
to kick the user off our session. Essentially, logging the user out of
our system.
In this case, we need access to our WOSession in order to log the user
out.
Thanks

What if I access and use a WOSession outside

WOApplication.saveSessionForContext() when i am done using it?
Yes, that is what checks it back in.
May I ask why you want to access the session outside of a RR loop?
Perhaps there is a better way to do what you need done.

Hi List,
I was wondering how WebObjects enforces serial access to the WOSession
(ie. request processing).
Does the "wo" request handler enforce serial access? Does the"wa"
request handler enforce serial access? Does
Application.dispatchRequest() enforce serial access?
Also, if I was to access a WOSession outside of a request-response
loop, how can I ensure that the WOSession is not processing a request
at the same time? How can I ensure that only one Thread accesses the
WOSession at a time that comes from a "da" request? How do I initialise
the WOSession correctly if I need access to it when not coming from a
"wo" request the "wosid" is not sent along with a "wa" request?
See WOSessionStore and related methods in WOApplication. See Practical
WebObjects pages 171 - 172,
Is WOApplication.restoreSessionWithID()
going to do "the right thing" when ever I call it? ie. is it going to
initialize the WOSession correctly? will it ensure serial access to the
WOSession? etc...
Yes.
