PersistenceManagerFactoryResourceDeployer

public class PersistenceManagerFactoryResourceDeployer extends Object implements com.sun.enterprise.server.ResourceDeployer
Handles PersistenceManagerFactory resource evnets in the server instance. When user adds a pmf resource, the admin instance fires a resource event. And the event is propagated to this object. The methods may be invoked concurrently, therefore synchronized is used.
