title: JAX-RS 2.0 change default implementation
body: <p>I'm trying to use RESTEasy as JAX-RS 2.0 client implementation. The problem is that I got runtime exception:</p>
  
  <pre><code>06-28 13:29:06.410: E/AndroidRuntime(5745): Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: org.glassfish.jersey.client.JerseyClientBuilder
  06-28 13:29:06.410: E/AndroidRuntime(5745):     at javax.ws.rs.client.ClientBuilder.newBuilder(ClientBuilder.java:103)
  </code></pre>
  
  <p>So the <code>newBuilder()</code> method is searching for <code>JerseyClientBuilder</code> if I understand it correct. How can I tell the system to use RESTEasy instead?</p>
