Subject Re: CSWS Connector : ServiceConstructionException: Failed to create service
Date Wed, 22 Jan 2020 12:16:52 GMT
The whole web services java + cxf architecture is pretty mysterious.  The
only way I've made progress is by finding code snippets in stackoverflow;
the documentation is not adequate.  BUT there are configuration files that
determine how the WSDL parser resolves references.  I don't know how we
would force that configuration to be in effect but something like that
would need to be done.  I'm just surprised that you're having this problem
when two other installations didn't.  There must be a difference somewhere.
