- - 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.
Since:

5.5.10
