Package org.glassfish.resources.deployer

Class CustomResourceDeployer

java.lang.Object

org.glassfish.resources.deployer.CustomResourceDeployer

All Implemented Interfaces:

ResourceDeployer

@Service
@Singleton
public class CustomResourceDeployer
extends Object
implements ResourceDeployer

Handles custom resource events in the server instance.

The custom resource events from the admin instance are propagated to this object.

The methods can potentially be called concurrently, therefore implementation need to be synchronized.

Note: Since a notification is not sent to the user of the custom resources upon undeploy, it is possible that there would be stale objects not being garbage collected. Future versions should take care of this problem.

Since:

JDK1.4
