The org.apache.wink.client packages are not available to JAX-RS applications that
use the WebSphere Application Server Java Platform, Enterprise Edition (Java EE) 7 JAX-RS 2.0 implementation.
When you migrate to JAX-RS 2.0, remove references to the org.apache.wink.client APIs from your application.
For maximum portability, use the standard
javax.ws.rs.client APIs where possible.
If your application must continue to use the Apache Wink Client API, you must package the API with the application.
