Thanks Charles! I would take a look at it. It'll take something to
convince my company to buy this though :).

Hi Yogesh,
You might want to check the JEP project at http://www.singularsys.com/jep/
. I haven t used it but I know projects using this for an
*apparently* similar problem.
Hope this helps
