Good Morning Richard
you can create the wsdl from the attributes/methods of your java class using
java2wsdl utility from Apache Axis Project
http://ws.apache.org/axis/java/architecture-guide.html
But I must caution the team that is implementing the SOAP mechanism to agree
upon known providers e.g XML-RPC/CORBA for this discussion take a look at
http://docs.pushtotest.com/axisdocs/apiDocs/org/apache/axis/deployment/wsdd/providers/package-summary.html
HTH,
Martin-

Ironically, my experience has been just the opposite... most of the
services I've dealt with have been for internal use only, and I guess
we're a bit behind in getting WSDL for it all. Not so bad when it's
internal-only stuff, a much bigger problem when dealing with external
services.

Nah, I referenced my StrutsWS project once (twice now!), so it's not
especially off-topic :) Certainly less so than some of the more recent
threads around here!
