Examples of org.codehaus.activemq.service.TransactionTask

org.codehaus.activemq.service.TransactionTask
The TransactionTask interface should be implemented by any class whose instances are intended to be executed as part of a transaction event. The class must define a method of no arguments called execute. @version $Revision: 1.2 $
