I have a java program that uses Torque and it is working fine with

Thread.sleep() but  after it wake up again, torque always throws an

this?.  This program don't do any  connection handling at all.

The exception indicates that this is a mysql problem. please search the net
for this mysql problem.
Well, as far as I can see, the problem is that torque reuse the same mysql connection for all its queries. This is in itself a good thing, because it would be a waste to open a new connection each time it perform a query, but when I put the application to sleep, the connection times out because it is not used in 2 hours.

But torque don't detect that the connection is timed out, and then it get this mysql error, when it tries to use the timed out connection.

As far as I can see there are 2 possible solutions: Either torque should detect that the connection is closed, and then open a new connection, or I should tell torque to close the connection before I call Thread.sleep and then tell torque to reopen the connection after the program wake up. But I could not find any api calls to do this.
