Here is a list of WSDLs documents which have been published with WSDL4Reg
in the IBM UDDI v2 test registry.
A nice way to validate the registration is to use the IBM UDDI or the
SOAP Client web sites.
The links for browsing and executing a service are redirected to the SOAP
Client web site. The advanced HTML based UDDI browser dynamically creates
an HTML form allowing execution of operations within the published service,
very impressive !
