here is an example that runs on JBoss 2.4.x
package monitor;
import org.jboss.util.ServiceMBeanSupport;
public class JBossMonitor extends ServiceMBeanSupport
implements JBossMonitorMBean, Runnable {
Thread monitor = null;
int interval = 3000;
public JBossMonitor() {}
public String getName() {
return "Monitor:name=JBossMonitor";
}
protected void startService() throws Exception {
// Create a new thread with this monitor
// Set it as a daemon
// start the thread
}
protected void stopService() {
monitor.interrupt();
}
// IMPLEMENT THE GETTERS AND SETTERS FROM THE INTERFACE DEFINITION
public void run() {
boolean running = true;
while (running) {
try {
// put the thread to sleep for the interval specified
// System.out the memory usage
// System.out the thread usage
}
catch (InterruptedException e) {
running = false;
}
}
}
private String getMem() {
return "Total Mem: " + Runtime.getRuntime().totalMemory() + " " +
"Free Mem: " + Runtime.getRuntime().freeMemory(); }
private String getThreads() {
ThreadGroup root = null;
root = Thread.currentThread().getThreadGroup();
while (root.getParent() != null)
root = root.getParent();
return "Thread Count: " + root.activeCount();
}
}
package monitor;
import org.jboss.util.ServiceMBean;
public interface JBossMonitorMBean extends ServiceMBean {
void setInterval(int interval);
int getInterval();
}

Hi,--
I'm trying to implment a simple model MBean with one attribute and one getter for that attribute. Everything seems to compile but when I look in the agent the MBean is registered but a detail view always gives a class not found exception (in the browser) of the class that is my managed resource. Does anyone know where I can find a simple working example of a Model MBean for JBoss 2.4.x
Thanks
Erik
