What's the meaning of this error?
LogicalDriverManagerXAConnection not closed, check yourcode!(Use -Djdbc.connection.debug=true to find out where theleaked connection was created)
I think if u use a profiler, you can understand the error in more detail.
You have probably tried to reopen a connection which is already open.This may be caused by picking a connection already open from aconnection pool and trying to reopen it. And this may be caused by aexception in a connection which is not handled carefully in finallyclause of exception handler and closing the connection.
