TC and applicationwide beans
Hi,
can tomcat swap beans from one application to another if both use the
classes?
If I have a webapp A which granted access to the system and uses a login
bean to store
the data, does tc accept this bean ( in the same session ) on the webapp B
with same classes?
Or is a new session created if the user switches from one app to another???
(related to tc 3.3.2dev)

If you need only one instance, how about some sort of static factory that
creates one instance of your bean JVM-wide?

Tomcat 3.3.x provides the lib/apps directory (see the README file in there)
for Jar files that contains classes to be shared among all webapps.
Sessions are not cross-context. Sessions are specific to the webapp they are
created in for security reasons. Sessions are created via a
"request.getSession()" call in your servlet or JSP.
So, you can use the same class definition of a bean in two separate webapps
if the class definition is in $TOMCAT_HOME/lib/apps...
(or alternatively, in the WEB-INF/lib directories of your two webapps, but
that is just wasted space). The webapps will create two separate instances
of your bean.
Regards,
Michael
