First create a class something like:

class CMailQueueShutdown extends Thread
{
private Timer m_oTimer;
public CMailQueueShutdown(Timer p_oTimer)
{
super();
m_oTimer = p_oTimer;
}

public void run()
{
CDataSource.log("*********************Stopping
session.***********************");
System.out.println("Closing down.");
m_oTimer.cancel();
}
}

and then somewhere in your main method add the following:

final Timer queueRunner = new Timer();
Runtime.getRuntime().addShutdownHook(new CMailQueueShutdown(queueRunner));

It works allright with JDK later then 1.3

Best regards,
Igor.
