org.photovault.dbhelper.ODMGXAWrapper
ODMGXAWrapper is a simple wrapper for ODMG transactions. When created it checks if there is currently an open transaction and if there is not it creates a new one. When calling commit() method the the object commits transaction if the transacttion is owned by this object. If it is not then nothing will be done.
