I&#39;m delighted to report that I can get this to work using the JRE 1.7, 64 bit, that is in early trials with Windows 7 with SP1.<br><br>You must have the server there to answer, naturally!  That part is running in Python but I will now work on making that Jython.<br>
<br>Thanks for the help, it got me on the right path fast.<br><br>Peter<br>
