RE: Lost Connection Error

Sorry - just assumed you were using tcp.

The ClockDaemon thread should die when the app is redeployed. 
The other threads die when there are no more references 
to the underlying connection. 
Try invoking System.gc() to run finalizers.
Also ensure that you aren't holding onto a
javax.naming.Context - this could keep the connection open.
