Back in 2004 the vendors wanted a "Google for web services". However they overlooked the contractual complexities between commercial entities that have to take place with human intervention before one company will consume the web service from another. So all thats really left as an application for UDDI is an intranet "endpoint directory" for which it is overkill.
Thanks to every one of you for your suggestions. I would like to know one more thing.
Do we really need to remember the tag names and attributes (which is mandatory/optional) mentioned in SOAP/WSDL/UDDI? The real exam expect us to do so?
Where there are more wonders there is less knowledge
