JSON Validation over WSDL

Github : https://github.com/rernas35/JsonValidationOverWSDL

In our team,  we need a json validator for REST services. We have done some investigation and found out that mostly Swagger and WADL  is used for this purpose.

Our infrastructure is not adequate for Swagger or WADL that's why we have implemented a json validation library that use WSDL definitions for schema.

If you have services that is exposed in both SOAP and REST but you don't have swagger or wadl support, you can use this validation library,

Sample wsdl is a simple web service that is composed of login, logout, search and buy operations.

Output of validation library is JSON-Schema.Spec is here.

Json-Schema :

{  
   "$schema":"http://json-schema.org/draft-04/schema#",

   "additionalProperties":false,
