Hi,

I got a problem... after idle for several hours, when I use
the sample program
to send presistent message, PersistenceException
thrown. The root cause of it
is a SQLException, Communication link failure.

The problem remains until I restart OpenJMS server.

Does anyone knows how to tackle this? Is it possible to
restart OpenJMS
programmatically?

Many Many Thanks in advance.

Best Regards,
Dante
