THANK YOU!!  That was exactly the problem.  How insane.  But thank you so
much for your help.

The error message you see in HTML is not created by Apache SOAP.  Your
WebLogic container is catching the NPE and returning this to you.  The real
job here is to understand what you get the NPE.  Unfortunately, it appears
you are using the 2.3.1 release of Apache SOAP, which hides the root cause
of the exception.  Shortly after 2.3.1 was released, the line

          throw new ServletException ("Error building response envelope: " +

was changed to 

          throw new ServletException ("Error building response envelope: " +
e, e); 

precisely to provide the information needed to track down exceptions like
you are experiencing.

In 2.3.1, the most common cause of exceptions like the one you are getting
is the deployment descriptor, specifically the element


Note that the character content of the element is the name of a Java class.
If the class is not found, the 2.3.1 code ignored the exception, but that
eventually led to an NPE.  The most common error is that the line above is
*not* equivalent to 




because the whitespace is significant.  I recommend you check your DD for
similar whitespace.

I also recommend you change from the 2.3.1 to a recent nightly build, but I
understand that many people want to stick with a formal release.
