Shad:
If you are on a Unix box, you can simply touch the .class file that you already
have designated in the repository. It will then reload it. I know that this is
not "fully manual" the way that you described, but anything that changes the
modification time of the class file will cause it to reload. You can even write
an admin interface to do this for you if you wish.
As for the second question, I cannot answer - I know that there is work on an
administrative applet for Jserv. Check http://java.apache.org for the project
names.
