wsdl generation error?

[Jeff Greif <jg...@alumni.princeton.edu>]

I deployed a service, apparently without problems, but when requesting the
<url>?wsdl for it, there is a problem with namespaces in the WSDL generator
(as shown in the stack trace below).

Is there something that can be added to the .wsdd file to make this problem
disappear?  Is there a chance that the wsdl generator needs to be able to
find the schema for the namespace and that's the problem?  If so, is there a
way to specify its location in the .wsdd file?

What is the meaning of the <namespace> sub-element of <service>?  I noticed
that some services declare a wsdlTargetNamespace <param>.  Is this (and
related params) used to control the generated wsdl?  Is there a list of
these parameters anywhere?

In general, the wsdd descriptor has pretty thin documentation (in the User
guide, installation guide and reference guide).  If there were an XML Schema
for it, people could probably make more sense of it, and determine whether
there were interesting looking options they hadn't tried yet.  I looked
through all the .wsdd files in the axis distribution to see if something
might apply, but found nothing appropriate.
