General problem with interface and implmenetation

[Stefan Henke <st...@gmx.de>]

Hi,

my question is not 100% specfic to the list topic, but a little bit more general for soap, wsdl and uddi.

I want to write a client with apache soap 2.2 which calls a list of webservice on the internet. I want to specify my own wsdl-definition which has to be implemented by all webservices I want to call.
If it is possible, I want to ask a uddi registry for all implementations of my interface to get the list of services I will ask.
In theory, the process is clear to me. My problem is that I don´t know how to find the implementations of my service. For many soap implementations it is possible to reference an external service interface in the service implementation. But e.g. axis, it produce its own wsdl-definiton at runtime which includes its own interface and implementation definition.

Do you have any idea how to do this? Maybe it is possible to create my own category in the uddi registry which all thebservices have to reference?

Thanks for any help
Stefan
