java apps and php apps sharing sessions

Does anyone have any experiences to share regarding this?

we run a ColdFusion/PHP/Java(cocoon) environment and I'll probably
figure out a way for all apps to be able to share sessions. I wanted to
see if there are already some solutions out there before I tackle this.

obviously performance is a major factor (which rules out using a
database). At the moment, I'm thinking along the lines of using the
servlet container's session management... meaning I write a wrapper
servlet which can be called by PHP and ColdFusion.

Hi Terence,

JIC you must tackle this yourself: I guess the easy part will be to make
php and java to use the same session ids. The hard part will be to share
the data in the session. It seems to me that
http://www.php.net/manual/en/functio...ve-handler.php
may be usefull for this. You may save the data in XML if you need
flexibility, or csv if the data's structure is simple. But shared memory
will definetly be faster - see
http://www.php.net/manual/en/ref.session.php, note under "Requirements".

Greetings,
Henk Verhoeven.

Thanks for the info.

session-set-save-handler() is a good place to start.
