I stumbled over the Excalibur project while googling - is it possible
to use it in order to achieve inter webapp communication in a servlet
container such as Tomcat, without having to put all jars that the two
webapps use in a shared dir (i.e. shared classloader) ?
For communication between different web applications, your best bets
probably are
* both use the same database backend
* use JNDI
* use J2EE (sorry JEE) features like EJB for the shared data
* communicate using something like RMI or AltRMI
* use some other communication protocol (servlets calling servlets
for example)
Of these, I would probably suggest JNDI. Of course, it is possible to
stuff things in an avalon container (like excalibur-fortress), and
then stuff that container in a JNDI context. That's what I've usually
done in the past :-)
We have experimented in the past with having servlet engines "on top
of" avalon/excalibur containers, allowing to share blocks between
them "the avalon way", but I don't think any of those efforts are
currently actively maintained.
Thank you in advance.
hope this helps,
Leo
