Major Description
I've added a framework for driver specific exception handling in tranql connector.
Each jdbc driver needs an ExceptionSorter subclass that can tell if the various SQLExceptions thrown by the driver mean that the connection is no longer usable.
To use this with a particular driver, pack the ExceptionSorter subclass into a jar (along with any other driver specific stuff) and use a dependency element in geronimo-ra.xml to include this jar (and another for the driver itself) in the classpath.
This is a great opportunity to contribute to geronimo without learning much about geronimo internals.
