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.

Since:

5.5.10
