Examples of org.activemq.util.ExceptionTemplate

org.activemq.util.ExceptionTemplate
A helper class for ensuring that a number of tasks occur, whether they throw exceptions or not and saving the first exception so that we can throw it properly. This class is particularly useful for shutting things down, where we want to try close all resources, whether they fail or not. @version $Revision: 1.1.1.1 $
