title: How do I debug server-side errors?
body: <p>Our Java application is going through migration from a WAS 7 server to a WAS 8.5 server - and for some reason, even though our application shows as Deployed in our Admin Console, the application itself isn't coming up on our assigned URL.  </p>
  
  <p>I've ruled out the possibility of a code-related problem by testing the application in my local server, so I know the problem is with some server settings - but, almost all of my experience in CS is in coding, and I don't know how to figure out where those settings have gone awry.  </p>
  
  <p>What options do I have to debug my application's server-side issues?  </p>
