Hi
amarnath1234A .wadl file can be considered the REST equivalent of a SOAP services .wsdl file.
The .wsdl (stands for webservices definition language) defines the listening webservice, such as method (e.g.POST,GET, etc.) along with the soap container and the SOAP services URL. A soap service doesn't use uri/template, query or header parms whereas a REST api does.
The URLS in a SOAP or REST api are determined by the developers who are defining the service/api from the requirements....its nothing to do with licensing.
I suggest reading up on REST, SOAP, .wsdl, .wadl and then come back with more questions. Restfulapi.net is a decent place to start. There's a lot of theory that you need to understand to be able to use readyapi!/soapui effectively.
Ta,
