The answer is simple: no.
Java provides no mechanism for unloading a class that has already been
loaded. The way that reloading is implemented for a webapp is to throw
away the entire class loader used to load that webapp, and starting over
again. If we did that for shared classes, however, you'd have to restart
*all* webapps because they would all need to be thrown away.
If you want to take advantage of the auto-reload capability to update
classes in a webapp, you *must* put those classes in /WEB-INF/classes, or
in a JAR file in /WEB-INF/lib.
