| javax.management.j2ee.Management
| Management | | public interface Management extends EJBObject(Code) | | 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.

| Method Summary | |
| public Object | getAttribute(ObjectName name, String attribute)
Gets the value of a specific attribute of a named managed object. | | public AttributeList | getAttributes(ObjectName name, String[] attributes)
Enables the values of several attributes of a named managed object. | | public String | getDefaultDomain()
Returns the default domain name of this MEJB. | | public ListenerRegistration | getListenerRegistry()
Returns the listener registry implementation for this MEJB. | | public Integer | getMBeanCount()
Returns the number of managed objects registered in the MEJB. | | public MBeanInfo | getMBeanInfo(ObjectName name)
This method discovers the attributes and operations that a managed object exposes for management. | | public Object | invoke(ObjectName name, String operationName, Object[] params, String[] signature)
Invokes an operation on a managed object
Parameters:
name - The object name of the managed object on which the method is to be invoked.
Parameters:
operationName - The name of the operation to be invoked.
Parameters:
params - An array containing the parameters to be set when the operation is invoked
Parameters:
signature - An array containing the signature of the operation. | | public boolean | isRegistered(ObjectName name)
Checks whether a managed object, identified by its object name, is already registered with the MEJB.
Parameters:
name - The object name of the managed object to be checked. | | public Set | queryNames(ObjectName name, QueryExp query)
Gets the names of managed objects controlled by the MEJB.
This method enables any of the following to be obtained:
The names of all managed objects, the names of a set of managed objects specified by pattern matching on the
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.
Parameters:
name - The object name pattern identifying the managed objects to be retrieved. | | public void | setAttribute(ObjectName name, Attribute attribute)
Sets the value of a specific attribute of a named managed object. | | public AttributeList | setAttributes(ObjectName name, AttributeList attributes)
Sets the values of several attributes of a named managed object. |
| getAttributes | | public AttributeList getAttributes(ObjectName name, String[] attributes) throws InstanceNotFoundException, ReflectionException, RemoteException(Code) | | Enables the values of several attributes of a named managed object. The managed object is identified by its object name.
Parameters:
name - The object name of the managed object from which the attributes are retrieved.
Parameters:
attributes - A list of the attributes to be retrieved. The list of the retrieved attributes.
throws:
InstanceNotFoundException - - The managed object specified is not registered in the MEJB.
throws:
ReflectionException - - An exception occurred when trying to invoke the getAttributes method of a Dynamic MBean.
throws:
RemoteException - - A communication exception occurred during the execution of a remote method call |
| getDefaultDomain | | public String getDefaultDomain() throws RemoteException(Code) | | Returns the default domain name of this MEJB.
throws:
RemoteException - RemoteException - A communication exception occurred during the execution of a remote method call getListenerRegistry |
| getListenerRegistry | | public ListenerRegistration getListenerRegistry() throws RemoteException(Code) | | Returns the listener registry implementation for this MEJB. The listener registry implements the methods that enable clints to add and remove event notification listeners managed objects
An implementation of javax.management.j2ee.ListenerRegistration
throws:
RemoteException - - A communication exception occurred during the execution of a remote method call |
| getMBeanCount | | public Integer getMBeanCount() throws RemoteException(Code) | | Returns the number of managed objects registered in the MEJB.
throws:
RemoteException - A communication exception occurred during the execution of a remote method call |
| invoke | | public Object invoke(ObjectName name, String operationName, Object[] params, String[] signature) throws InstanceNotFoundException, MBeanException, ReflectionException, RemoteException(Code) | | Invokes an operation on a managed object
Parameters:
name - The object name of the managed object on which the method is to be invoked.
Parameters:
operationName - The name of the operation to be invoked.
Parameters:
params - An array containing the parameters to be set when the operation is invoked
Parameters:
signature - An array containing the signature of the operation. The class objects will be loaded using the same class loader as the one used for loading the managed object on which the operation was invoked. The object returned by the operation, which represents the result of invoking the operation on the managed object specified.
throws:
InstanceNotFoundException - - The managed object specified is not registered in the MEJB.
throws:
MBeanException - - Wraps an exception thrown by the managed object's invoked method.
throws:
ReflectionException - - Wraps a java.lang.Exception thrown while trying to invoke the method.
throws:
RemoteException - - A communication exception occurred during the execution of a remote method call getDefaultDomain |
| isRegistered | | public boolean isRegistered(ObjectName name) throws RemoteException(Code) | | Checks whether a managed object, identified by its object name, is already registered with the MEJB.
Parameters:
name - The object name of the managed object to be checked. True if the managed object is already registered in the MEJB, false otherwise.
throws:
RemoteException - A communication exception occurred during the execution of a remote method call |
| queryNames | | public Set queryNames(ObjectName name, QueryExp query) throws RemoteException(Code) | | Gets the names of managed objects controlled by the MEJB.
This method enables any of the following to be obtained:
The names of all managed objects, the names of a set of managed objects specified by pattern matching on the
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.
Parameters:
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. A set containing the ObjectNames for the managed objects selected. If no managed object satisfies the query, an empty set is returned.
throws:
RemoteException - A communication exception occurred during the execution of a remote method call |
| setAttributes | | public AttributeList setAttributes(ObjectName name, AttributeList attributes) throws InstanceNotFoundException, ReflectionException, RemoteException(Code) | | Sets the values of several attributes of a named managed object. The managed object is identified by its object name.
Parameters:
name - The object name of the managed object within which the attributes are to be set.
Parameters:
attributes - A list of attributes: The identification of the attributes to be set and the values they are to be set to. The list of attributes that were set, with their new values.
throws:
InstanceNotFoundException - - The managed object specified is not registered in the MEJB.
throws:
ReflectionException - - An exception occurred when trying to invoke the setAttributes method of a Dynamic MBean.
throws:
RemoteException - - A communication exception occurred during the execution of a remote method call invoke |
