  - - org.apache.tools.ant.Task
    - - org.apache.catalina.ant.BaseRedirectorHelperTask
      - - org.apache.catalina.ant.jmx.JMXAccessorTask

- All Implemented Interfaces:
    Cloneable

      public class JMXAccessorInvokeTask
      extends JMXAccessorTask

  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:
  - Get a session attribute hello from session with ref ${sessionid.0} form app Catalina:type=Manager,context=/ClusterTest,host=localhost

           <jmx:invoke
                   name="Catalina:type=Manager,context=/ClusterTest,host=localhost"
                   operation="getSessionAttribute"
                   resultproperty="hello">
                 <arg value="${sessionid.0}"/>
                 <arg value="Hello"/>
           </jmx:invoke>

  - Create new AccessLogger at localhost `<jmx:invoke name="Catalina:type=MBeanFactory" operation="createAccessLoggerValve" resultproperty="accessLoggerObjectName" > <arg value="Catalina:type=Host,host=localhost"/> </jmx:invoke>`
  - Remove existing AccessLogger at localhost `<jmx:invoke name="Catalina:type=MBeanFactory" operation="removeValve" > <arg value="Catalina:type=Valve,name=AccessLogValve,host=localhost"/> </jmx:invoke>`

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

  These tasks require Ant 1.6 or later interface.
