## Class JMXAccessorSetTask

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

- All Implemented Interfaces:
    Cloneable

      public class JMXAccessorSetTask
      extends JMXAccessorTask

  Access JMX JSR 160 MBeans Server.
  - Get Mbeans attributes
  - Show Get result as Ant console log
  - Bind Get result as Ant properties

  Examples: Set a Mbean Manager attribute maxActiveSessions. Set this attribute with fresh jmx connection without save reference

         <jmx:set
                 host="127.0.0.1"
                 port="9014"
                 ref=""
                 name="Catalina:type=Manager,context="/ClusterTest",host=localhost"
                 attribute="maxActiveSessions"
                 value="100"
                 type="int"
                 echo="false">
             />

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

  These tasks require Ant 1.6 or later interface.
