Subject svn commit: r1004684 - in /axis/axis2/java/core/trunk/modules/kernel/src/org/apache/axis2/deployment: DeploymentEngine.java scheduler/SchedulerTask.java
Date Tue, 05 Oct 2010 15:52:39 GMT
Author: azeez

New Revision: 1004684

URL: http://svn.apache.org/viewvc?rev=1004684&view=rev
Log:
Added a method to check whether the deployment task is running. If an Axis2 server is shutdown
while the deployment task is running, there can be exceptions that are thrown. So. in a graceful
shutdown scenario, we can first check whether the deployment task is running, and then initiate
the shutdown procedure, once the task has ended.
