I am just beginning to test out Apache soap. I have deployed a serviced
using a simple DD, and the ServiceManagerClient. The SOAP admin client's
Service Listing page confirms a successful deployment. I have written a
simple Java client to communicate with the server (based 90% on the "Hello
client" program demonstrated in the O'Reilly SOAP book), but when I try to
make a call, I always get the following response from my server:
<head><title>Error: 500</title></head>
<body>
<h1>Error: 500</h1>
<h2>Location: /soap/servlet/rpcrouter</h2><b>Internal Servlet Error:</b><br>
<pre>javax.servlet.ServletException: Error building response envelope:

Can anyone offer some suggestions as to why the servlet seems to be blowing
up on a very simple request?
Thanks,
