title: Target runtime JBoss v4.2 is not defined
body: <p>I have imported a project and got the error "Target runtime JBoss v4.2 is not defined".
  I have added the JBoss 4.2 Runtime library.  However, the error is still there.</p>
  
  <p>In my Java Build Path, I have the followling libraries added already.</p>
