  • An instance of MBeanInfo allowing all attributes and actions exposed by this Dynamic MBean to be retrieved.

public abstract Object invoke (String actionName, Object[] params, String[] signature)

Allows an action to be invoked on the Dynamic MBean.

Parameters
actionName The name of the action to be invoked.
params An array containing the parameters to be set when the action is invoked.
signature An array containing the signature of the action. The class objects will be loaded through the same class loader as the one used for loading the MBean on which the action is invoked.
Returns
  • The object returned by the action, which represents the result of invoking the action on the MBean specified.
Throws
MBeanException Wraps a java.lang.Exception thrown by the MBean's invoked method.
ReflectionException Wraps a java.lang.Exception thrown while trying to invoke the method
