Hi, Noah.

You might have better luck checking the lists at
xml.apache.org. This error is not familiar to me.

I'm wondering if you ran the deploy script
successfully before getting this error? Can you tell
if the "mastercontrolprogram" is deployed on your
server? 

Also, it's possible that there is a version conflict
with SOAP and your JSP server. Perhaps it requires a
particular version of Apache SOAP? Also, make sure
that all the class paths are set on your server. Can
it see xerces.jar, for example? 

As you can see, I'm grasping at straws. If you
discover something on xml.apache.org, please let me
know.

Good luck.
