I am running PI 7.0.
I have created several Web Services on Integration Directory, using Define Web Service feature. Where are they stored? Where can I find them? Where do I list them, to see which is the WSDL for each one? I tried the web services navigator but they are not there.
The features that you had described (WSDL/Service Search, Storing of WSDL's, sisible in Webservice Navigator) are not available in PI7.0. They have been incorporated from PI7.1.
With PI7.0, the WSDL that you had generated(& stored on local desktop) should be directly used in your target applications. Extra effort has to be take if you want to publish these to UDDI.
