Have you checked out the Tomcat Manager application?  It's included
with the Tomcat application, and is accessible at
{your-url}:8080/manager/html.

You need to set it up before using it, but it's pretty nice when you
get it going.  Here's a reference to how you reload JSP webapps with
it:

g%20Application

Hope this helps,

Gregor,  if you replace the war file , with the recompiled classes, in
the Jboss deployment directory, it will reload the classes. Try it out.
You dont have to restart.

You need to create new class loader to load the new version.  Then you
have both new and old objects lying around inside the JVM.

This has been covered far too often for me to want to go into detail again, but
broadly you have to look into using your own classloader(s).  Use your own
explicitly created classloader to load your "hot swappable" classes.  When you
want to reload, discard all references to that classloader, the classes it
loaded, and any instances they may have.  Reload by creating a new classloader
and using it to load the new class defintions.
