Examples of javax.ws.rs.client.Invocation.invoke()

javax.ws.rs.client.Invocation.invoke()
Synchronously invoke the request and receive a response back. @return {@link Response response} object as a result of the requestinvocation. @throws ClientException in case the invocation processing has failed.
