Why don't you email me what's in the workers.properties as well.

Usually I enable java on a per site basis and not globally. You might
want to try it that way instead of globally. It's a pain but put the
JKMount stuff in each virtual site between the virtual tags.

Good.

It might be that those are outside of the virtual site tags. Could be a
mood issue and have nothing to do with your problem.

That's a start.

You will need to have a web.xml file, and in it should contain any
servlets that need to be started, and used.

It may still be required even outside of the one in the different apps.
Worse case just leave the one at the doc base empty. Include the basic
stuff, but leave out any servlet entries. Something like

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
    "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd";>

<web-app>

</web-app>

I would leave the context path as is, and try the suggestion above.

Good otherwise servlets will not be started. Even if specifying them in
the web.xml files.

There are still plenty of things to look into.

No worries. We will get you there sometime soon.
