Classloader Problem

["Wax, Michael" <mw...@vantra.com>]

I am using Tomcat 4.0 with JBoss 2.4.  I am able to call JBoss session beans
from my servlets without problem.  However, when I attempt to call a session
bean from the finalize method of a helper class, I get a
ClassNotFoundException, no matter where I put my JBoss client classes.  It
seems clear that the JBoss proxy classes are using the wrong class loader
when called from finalize.  Any thoughts?

That sounds like something you really ought to ask on the JBoss support
lists.

As a general principle, I *never* design my classes to clean up only in
the finalize() method.  That's letting things hang around far longer than
they really should (and therefore impacting the performance of all users
of the JVM you are running in) -- clean up after yourself when you are
done using a particular object.
