JMXExporter for Dynamic Beans

[SpringBuddy]

Friends ..

I have some configurations which has been configured in Database,
base on the configuration my programe is instantiating 5 processor objects,(Thats why i called those objects as Dynamic bean)and i have to monitor(start and stop ) some methods using jmx client remortly(using RMI)
If so how can i export those beans(5 processor)through org.springframework.jmx.export.MBeanExporter, Please help me out.

Advance thanks.

Cheers

after all round of debug i have written my custom exporter as follows

import javax.management.modelmbean.ModelMBean;
import javax.management.modelmbean.ModelMBeanInfo;


import org.springframework.jmx.export.MBeanExporter;
import org.springframework.jmx.export.SpringModelMBean;
import org.springframework.jmx.export.assembler.MBeanInfo Assembler;
import org.springframework.jmx.export.assembler.SimpleRef lectiveMBeanInfoAssembler;
import org.springframework.util.ObjectUtils;




/**
*
* @author dominic.s

*/
public class CustomMBeanExporter extends MBeanExporter {


private static final String MR_TYPE_OBJECT_REFERENCE = "ObjectReference";

/** Stores the MBeanInfoAssembler to use for this exporter */
private MBeanInfoAssembler customAssembler = new SimpleReflectiveMBeanInfoAssembler();

public void doCustomRegister(String objectName, Object obj) throws RuntimeOperationsException, JMException, InvalidTargetObjectTypeException{
String objectTmp = "domain: key1 = value1 , key2 = value2";
ObjectName customObjectName = ObjectName.getInstance(objectTmp);

ModelMBean mbean = new SpringModelMBean();// Model Bean new SpringModelMBean()
mbean.setModelMBeanInfo(getMBeanDetails(obj, objectTmp));
mbean.setManagedResource(obj, MR_TYPE_OBJECT_REFERENCE);

doRegister(mbean, customObjectName);

}


/**
* Gets the <code>ModelMBeanInfo</code> for the bean with the supplied key
* and of the supplied type.
* Overide method of getMBeanInfo of Parent.
*/
private ModelMBeanInfo getMBeanDetails(Object managedBean, String beanKey) throws JMException {
ModelMBeanInfo info = this.customAssembler.getMBeanInfo(managedBean, beanKey);

return info;
}

Here is my Dynamic Class
package com.habuma.spitter.jmx;


import java.io.Serializable;


import javax.inject.Named;




public class CustomMBean implements Serializable {

private String name = "Default";


public String getName() {
return name;
}


public void setName(String name) {
this.name = name;
}




}
------------------------------------------------------------------------------------------------------------
Here is my Sample Test Main
package com.testing;


import javax.management.JMException;
import javax.management.RuntimeOperationsException;
import javax.management.modelmbean.InvalidTargetObjectTyp eException;


import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlAp plicationContext;
import org.springframework.jmx.export.MBeanExporter;


import com.habuma.spitter.jmx.CustomMBean;
import com.habuma.spitter.jmx.CustomMBeanExporter;
import com.habuma.spitter.jmx.SpittleNotifier;


public class TestJmx {


/**
* @param args
* @throws InterruptedException
* @throws InvalidTargetObjectTypeException
* @throws JMException
* @throws RuntimeOperationsException
*/
public static void main(String[] args) throws InterruptedException, RuntimeOperationsException, JMException, InvalidTargetObjectTypeException {
//Load the Application Context.
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:jmx-context.xml","classpath:mbean-exporter-context-basic.xml");



CustomMBeanExporter exporter = (CustomMBeanExporter)applicationContext.getBean("m beanExporter");

CustomMBean customMBean = new CustomMBean();

exporter.doCustomRegister("CustomMBeans", customMBean);

System.out.println("Application Sucessfully loaded....");

while(true){
System.out.println(customMBean.getName());
Thread.sleep(2000l);
}
}


}


Thanks and Regards
