$CATALINA_HOME/common/lib or WEB-INF/lib
Hi there..
I have 15 apps on my Tomcat. Five of them require library abc.jar
(~1,5MB). From the resources point of view (mem, cpu) is it better to
make abc.jar visible globaly to all applications (place it in
$CATALINA_HOME/common/lib) or copy to WEB-INF/lib of all five dependent
applications?
Regards,
prp

shared/lib if you want the applications to share resources, such as
singletons.,
otherwise, add them to each WEB-INF/lib, makes life simpler in the long run

Mentioned webapps are strictly related. In fact they are part of one
large system. What is the best way to add make library/libraries
available to all application? Put it in $CATALINA_HOME/common/lib or is
there better way to do that?

Using a single copy would save memory, but not a very large amount
compared to the size of 15 typical webapps. More significant are the
convenience factors:
Using a single shared copy of the lib is good if the webapps are all
related and you need to make sure they're all using the same version
of the shared lib. Multiple copies can get out of sync.
Using separate copies is good if the webapps are independent, and
you're worried about an update to the shared lib causing compatibility
problems with the other 14 apps. Also, if each webapp has its own
copy, the lib is part of each app's .war; but a shared copy requires a
separate installation step.
