SAXException: Invalid Element error in AXIS client

[Steve Pannier]

I'm using an Axis1.1RC2 client to invoke a method that returns a structure
containing 2 strings.  I'm getting the following error from my client:


org.xml.sax.SAXException: Invalid element in

Here's the SOAP response message:

  </ns1:GetStringResponse>

The WSDL I used to create my test client is below.

      </wsdl:port>
   </wsdl:service>
</wsdl:definitions>



Any ideas as to what the problem is?  Is the SOAP response formatted
incorrectly?  Or could something be wrong in the WSDL file?
