Hi guys
We're currently trying out the muse frameworks ability to create and
destroy WDSM enabled WsResources, but we seem to have run into a slight
problem with the correct way to destroy these resources.
A fast overview goes as follows:
1) We've a factory to create resources on the fly.
2) We change a couple of the values held by the resource (to get the
on-change WS-N sent out)
3) Next we attempt to clean up, by destroying the WsResources
4) We run the whole thing again from 1) without restarting the Tomcat
server
Notes regarding software usage:
MUSE 2.0.0
Java SDK 1.5_07
Axis 2.0
The printout from the shutdown (destruction) process is:
11-Jan-2007 14:21:27 org.apache.muse.core.SimpleResource shutdown
INFO: [ID = 'ResourceDestroyed'] The resource at 'WsResource' has been
destroyed.
Though it seems as if, even though the prepareShutdown() function has
been overridden, that our override doesn't run.
** overridden initializeComplete()
public void initializeCompleted() throws SoapFault {
super.initializeCompleted();
publishMessage("we have been created");
}
** overridden prepareShutdown()
public void prepareShutdown() throws SoapFault {
super.prepareShutdown();
getLog().info("calling shutdown");
}
Our problem is that upon the 2nd run of the process (without shutting
down the server) we get the following error message from the
SimpleAdvertisement:
INFO: [ID = 'ResourceInitialized'] The resource at 'SubscriptionManager'
has been initialized.
java.lang.NullPointerException
