Everything looks good to me. A couple things you could try:

1. We just started with the .jar files, so I am naturally suspicious 
that the problem may be there. So as an alternative, put the jBox.class 
and evalThread.class files into java/jBox/ directory instead of 
jBox.jar. And remove the archive="jBox.jar" line.

2. Is java/jBox/ accessible from your browser? I quick test would be to 
but some file in java/jBox/ and then check that it displays in your 
browser. For example, if you put a file named "test.html" in java/jBox/,
then from your browser go to http://localhost/java/jBox/test.html and 
verify that you can see it.
