public class HAManagementService

implements HAManagementServiceMBean

This class enables a client to get a management view (JSR-77) on a JBoss Cluster. It contains the entire logic to map all the {@link org.jboss.management.j2ee.J2EEManagedObject Managed Object (MO) of all the nodes in the cluster to one MO. The same applies to State Management and Performance Statistics.

Constructor Detail

HAManagementService

public HAManagementService()

Creates a undefined clustering management service. Before this MBean can be started the HAPartition must be up and running.

ATTENTION: The current implemenation is a brute force one because it is retrieving the data on every hit. Later on this has to be resolved with a caching to avoid unecessary round-trips.
