Package com.google.apphosting.runtime.jetty9

Class TransactionCleanupListener

java.lang.Object

com.google.apphosting.runtime.jetty9.TransactionCleanupListener

All Implemented Interfaces:

RequestListener, EventListener

public class TransactionCleanupListener
extends Object
implements RequestListener

TransactionCleanupListener looks for datastore transactions that are still active when request processing is finished. The filter attempts to roll back any transactions that are found, and swallows any exceptions that are thrown while trying to perform roll backs. This ensures that any problems we encounter while trying to perform roll backs do not have any impact on the result returned the user.
