title: Tomcat Client Authentication using SSL
body: <p>I'm at a loss, since I'm not a Tomcat person. I need to use a 3rd party's web service and they require Client Authentication via SSL, so they generated and issued me an SSL certificate. Unfortunately this is as far as they support it and cannot give me any direction on how to actually <em>use</em> it. I'm stuck using this 3rd party so unfortunately I have to put up with their lack of support.</p>
  
  <p>So what I have is a Java application that a vendor is supplying for us (who apparently has never had to deal with this), a Tomcat app server running 6.0.20 on CentOS 5.3, and the SSL cert from the 3rd party.</p>
  
  <p>What all do I need to do at this point? All I can find online is how to set up a keystore so that my app can use Client Authentication against things connecting to it, not for when it needs to connect out to someone else, or how to use SSL over port 8443 (which I know how to do already and have set up).</p>
