Simple question, which version of MySQL and Connector/J are you
using? Upgrading them to the latest versions might help.

Hi guys,
just to give you a short update on what happened since my last Mail
to this list: The decision was made to use PHP for the frontend and
RIFE/Crud for the administration interface. Both are almost ready
now, but there's a bug in the admin interface we can't get rid of.
The error message is attached. This problem occurs only after
Tomcat has been running for awhile. A restart fixes this problem
temporarily. Basically looks like RIFE is trying to keep some
connection alive, while MySQL times out.
Please note, that we currently still use RIFE 1.4, so sorry if this
is fixed in 1.5.
Another thing: Personally, I've really fallen in love with RIFE.
The frontend will soon be ported to RIFE, also and will then be
released as an OpenSource Online Shop. First Pre-Release is
scheduled somewhere in the late third quarter 2006 if everything
goes well. And someone has asked me to write a book on RIFE and
OpenLaszlo, so I'll think about that, too.
Best Regards,
Stefan Thomas
