Introduction

In this page you can find the example usage for javax.management MBeanServerConnection invoke.

Prototype

public Object invoke(ObjectName name, String operationName, Object params[], String signature[])
        throws InstanceNotFoundException, MBeanException, ReflectionException, IOException;

Source Link

Document

Invokes an operation on an MBean.

Because of the need for a signature to differentiate possibly-overloaded operations, it is much simpler to invoke operations through an JMX#newMBeanProxy(MBeanServerConnection,ObjectName,Class) MBean proxy where possible.
