[Vivek Nigam] Re: destroy method is not destroying the OutOf Process EclipseEngine!!

attached mail follows:

Hello Andrew,

                Thank for your quick response (I was very surprised
that someone answered so quickly... ;) ).

                Amazing, you got it just right!!!, I was using another
thread to close the connection... I made the changes as you suggested
and it worked...

                If you need the code, I can prepare it and send it to
you (case want to analyze it...).

Thanks a lot!!!

Vivek Nigam
