I understand it makes no sense to share a whole webapp in Tomcat.
What about sharing a singleton across all Tomcat webapps? I want my main
webapp to call a method on that shared singleton in order to provide a
factory (...getInstance().setFactory()). This factory should be retrieved by
webapps using that singleton (....getFactory()). I know I have to put that
singleton (in a jar file) into the $CATALINA_HOME/lib directory. How do I
access the singleton from within my webapps after that? I guess I have to
touch the web.xml somewhere. However, the first call must set the factory
(the main webapp will do that)... all following calls shall be able to
access the factory.

Subject: Using shared Spring Webapp in Tomcat 6
For Tomcat 6 there is a folder called "$CATALINAHOME/lib"
that is said to be used for that kind of stuff.
No, the $CATALINA_HOME/lib directory is for classes common to all
webapps, not any individual webapps. Each webapp is normally deployed
in its own directory under the <Host> appBase (typically
$CATALINA_HOME/webapps).
1.) Does it work to create a war file from my services webapp
and put it into the lib directory? Is this the way to go?
No.
2.) Furthermore: Where do I start with my JSP/JSF view
webapp? I assume I have to access the SessionFacade somehow.
I will have to access the logic web app from within my view-webapp.
If your "logic" webapp is just that - no presentation capabilities -
then it's not really a webapp, is it? Sounds like you haven't really
thought through the application architecture here.
This may well be more of a Spring topic than a Tomcat one.
