Hi, Martin:
Thanks for your hints!
I have got a service named RgbWSDFAtt and the "resourceClass" is
"PersistentRgbWSDFAtt" and the signature of this class is:
public class PersistentRgbWSDFAtt
extends RgbWSDFAtt
implements PersistenceCallback, RemoveCallback {
...
// I also implemented the remove() method
public void remove() throws ResourceException {
//Remove the resource...
}
...
}
However, I feel this has never been invoked. I am not sure if the
parameters in the deploy-jndi-config.xml has been configured properly so the
wscore server understands when it should remove the resource.
