  <p>I am posting this up in the hope that someone who has been bitten by this before can simply reel off the answer - this question features heavily on Oracle and DevX forums when I post the stack into Google, and has not been answered.</p>
  
  <p><strong>Note:</strong> Company constraints insist on the use of the specific version of the software quoted at the top of the question - I am fully aware that this version of WebLogic is not Java EE 6 compliant.</p>
