public interface Management
The Management interface provides the APIs to navigate and manipulate managed objects. The J2EE Management EJB component (MEJB) must implement this as its remote interface.

java.util.Set queryNames(javax.management.ObjectName name, javax.management.QueryExp query) throws java.rmi.RemoteException
ObjectName
, a specific managed object name (equivalent to
testing whether a managed object is registered). When the object name is
null or no domain and key properties are specified, all objects are selected.
It returns the set of J2EEObjectNames for the managed objects selected.
name
- The object name pattern identifying the managed objects to be retrieved. If
null or no domain and key properties are specified, all the managed objects registered will be retrieved.

retrieved.

name
- The object name of the managed object from which the attributes are
retrieved.attributes
- A list of the attributes to be retrieved.
