## Class JMXAccessorTask

- java.lang.Object
- - org.apache.tools.ant.ProjectComponent
  - - org.apache.tools.ant.Task
    - - org.apache.catalina.ant.BaseRedirectorHelperTask
      - - org.apache.catalina.ant.jmx.JMXAccessorTask

All Implemented Interfaces:
  Cloneable

Direct Known Subclasses:
  JMXAccessorCreateTask, JMXAccessorGetTask, JMXAccessorInvokeTask, JMXAccessorQueryTask, JMXAccessorSetTask, JMXAccessorUnregisterTask

    public class JMXAccessorTask
    extends BaseRedirectorHelperTask

Access JMX JSR 160 MBeans Server.

- open more then one JSR 160 rmi connection
- Get/Set Mbeans attributes
- Call Mbean Operation with arguments
- Argument values can be converted from string to int,long,float,double,boolean,ObjectName or InetAddress
- Query Mbeans
- Show Get, Call, Query result at Ant console log
- Bind Get, Call, Query result at Ant properties

Examples: open server with reference and autorisation

        <jmxOpen
                host="127.0.0.1"
                port="9014"
                username="monitorRole"
                password="mysecret"
                ref="jmx.myserver"
            />

All calls after opening with same refid reuse the connection.

First call to a remote MBeanserver save the JMXConnection a referenz jmx.server

All JMXAccessorXXXTask support the attribute if and unless. With if the task is only execute when property exist and with unless when property not exists.
NOTE : These tasks require Ant 1.6 or later interface.

  5.5.10
