title: how to verify if java sends the client certificate in a mutual auth scenario
body: <p>I setup 2way ssl with Camel and CXF using the http conduit element etc.
  I make a webservice call to an external party. All certificates are correctly installed (incoming traffic is succesfull, this is configured in Tomcat). After <a href="https://stackoverflow.com/questions/6680416/apache-cxf-exception-in-ssl-communication-sockettimeout">this</a> post about secure renegotiation I finally received a response from the other party: HTTP response 403, forbidden. </p>
  
  <p>I've been debugging with javax.net.debug=all and <a href="http://docs.oracle.com/javase/1.5.0/docs/guide/security/jsse/ReadDebug.html" rel="nofollow noreferrer">this</a> excellent explanation.
  I can see in the logging that a secure connection is succesfully setup:</p>
  
  <pre><code>*** Finished
  verify_data:  { 141, 25, 184, 254, 93, 9, 10, 48, 135, 161, 213, 57 }
  ***
  %% Cached client session: [Session-2, SSL_RSA_WITH_RC4_128_MD5]
  </code></pre>
  
  <p>and no other errors or warnings. How can I verify if my client certificate is sent to the server? (I can't use Wireshark but I have the javax.net.debug logging)</p>
