Help with using OJB with Tomcat
Hi,
Can anyone point me to documentation/info on configuring OJB with
Tomcat. I have ran into a problem where two web apps running on the
same Tomcat instance that are supposed to use the same OJB cache seem to
get their own instances. Therefore changes to data in one app are not
reflected on the other.
TIA
Kind regards,

Hi Jason,
Yes the two apps were self contained. I have tried to change this by
implementing a factory object in Tomcats GlobalNamingResources that
creates PersistenceBroker objects but have ran into problems casting the
object back once it returns from a JNDI lookup(). At that point I
thought there must be some documentation/info to hand hold me through
it. Or, as you might be implying, an alternative way of configuring OJB
to be shared in Tomcat.

Do the two webapps have there own OJB instances (as in separate JAR
files, OJB.properties etc) in their own respective WEB-INF/lib,
WEB-INF/classes area? Or are they using shared resources through
something like tomcat/common/lib?
