Error while creating web service proxy from wsdl in Jdeveloper

I am getting the below error while creating the web service proxy in JDeveloper,

oracle.jdeveloper.webservices.model.WebServiceException: Error creating model from wsdl 

I am using Jdeveloper 11.1.1.6.0

Problem:

The problem is in JDeveloper 11.1.1.6.0 (i am not sure about other versions) when you try to create web service proxy in a project which has "ADF Model Runtime" library as a dependency (it is dependent on some other project which has ADF Model Runtime) the proxy creating will fail.

Solution:

Solution 1. Remove the ADF Model Runtime depdency and create web service proxy and then add the dependency again.

Solution 2. Just create an other generic project and create a proxy there and call the proxy.

Solution 3. You can create the web service as a data control in the same project and use it.
