From source file:org.zenoss.jmxnl.NotificationListener.java

@SuppressWarnings("unchecked")
private void connect() throws IOException {

    JMXConnector connector = JMXConnectorFactory.connect(url, environment);
    connector.addConnectionNotificationListener(this, null, "placeholder");
    MBeanServerConnection connection = connector.getMBeanServerConnection();

    log.info(url + ": Connected.");
    sendConnectionEvent("0", "JMX connection has been restored");

    Set<ObjectName> results = connection.queryNames(scope, null);
    java.util.Iterator<ObjectName> iter = results.iterator();
    while (iter.hasNext()) {
        ObjectName objName = (ObjectName) iter.next();
        String type = objName.getKeyProperty("type");
        if (type == null || !type.equals("alias")) {
            try {
                connection.addNotificationListener(objName, this, attributeFilter, zenossDevice);
                log.debug("Added notification listener: " + objName);
            } catch (IllegalArgumentException e) {
                log.debug("Can't listen to " + objName + " because it is not a notification broadcaster.");
            } catch (InstanceNotFoundException e) {
                log.debug("Can't listen to " + objName + " because it was not found on the server.");
            }/*from   www  . j a v  a  2  s.  c  o m*/
        }

        // There can be a lot of listeners to add. Give other threads a
        // chance to get work done while this happens.
        Thread.yield();
    }
