Placing classes jdk/jre/lib/ext puts them into the system classloader. This
opens a whole class of class not found errors and errors related to tomcat
not reloading classes. (As well as memory leaks due to Classloaders not being
freed)

That is not strictly true, We had an application at work that used JNI and
was part of a Database access library as well as accessing things like the
Machines Hostmac address.
We could not run it from the Tomcat area and had to put it into a jar file
and put the jar file into the JVM jdk/jre/lib/ext dir and then it worked
fine as any classes / libraries in that dir are loaded by the JVM meaning
they are always available - This is also where we put the JDBC driver jar.

Subject: Re: Load class from different web app
You are violating the servlet spec. Do not pass go, do not collect $200.
Classes for a webapp need to be in WEB-INF/classes and WEB-INF/lib. Tomcat
does allow for webapps to share classes via the $CATALINA_HOME/shared and
$CATALINA_HOME/common directories but you'll need to see the classloader
docs
on any restrictions.

I'm writing a web application (a portal app, to be specific) that needs to
be able to load a class (using Class.forName(...)) that was deployed in a
different web application from the one I am developing. I've deployed the
target web app containing the class I want to load, but whenever I call
Class.forName(), I get a "java.lang.ClassNotFoundException". Is there
anything special I need to do if I want to load this class? It appears it
is
a classloader issue, but I don't know enough to determine what the problem
is. Any help is greatly appreciated!
