> I've deployed a web service whose WSDL contains various schema imports without schemaLocations:
> {code:xml}<xs:import namespace="http://schemas.ggf.org/jsdl/2005/11/jsdl"/>{code}
> These imports are resolved via a jax-ws-catalog.xml:
> {code:xml}
> <public
>     publicId="http://schemas.ggf.org/jsdl/2005/11/jsdl"
>     uri="schemas/ext/jsdl/jsdl-1.0.xsd"/>
> {code}
> Accessing this WSDL via Geronimo with the ?wsdl-URL results in a NullPointerException
on Tomcat/Axis. The code tries to update the schemaLocation to a server-local URL and, for
this reason, retrieves the imported schema. But it never checks for a valid return value.
Jetty/CXF simply copies these import-elements to the output WSDL without further ado.

> IMHO, both assemblies should first consult an existing jax-ws-catalog.xml to resolve
the schemaLocations. If this doesn't work they should copy the import verbatim and let the
client resolve via its own catalog.
