JMX-Log4j Appender problem

Question

Dear listers
we wrote thefollowing code to log the loglevel's dynamically.
Following is the code
public class MyApp implements MyAppMBean {     
private static Logger logger = Logger.getLogger(MyApp.class);
public void go() throws Exception{
while(true){
logger.debug("DEBUG") ;
logger.info("INFO") ;
logger.warn("WARN");
logger.error("ERROR");
logger.fatal("FATAL");
Thread.sleep(2000);
public void setLoggingLevel(String level){
logger.info("Setting logging level to: " + level);
Level newLevel = Level.toLevel(level, Level.INFO);
Logger.getRootLogger().setLevel(newLevel);
public String getLoggingLevel(){                       
return Logger.getRootLogger().getLevel().toString() ;
public static void main(String[] args) throws Exception
DOMConfigurator.configure("log4j.xml");
MyApp app = new MyApp();
//Lookup for the mbean server
MBeanServer server = ManagementFactory.getPlatformMBeanServer();
//Create and register the top level log4j MBean
HierarchyDynamicMBean hdm = new HierarchyDynamicMBean();
ObjectName mbo = new ObjectName("log4j:logger=root");
System.out.println("Debug10");
server.registerMBean(hdm, mbo);
LoggerRepository r = LogManager.getLoggerRepository();
Enumeration<Logger> elogs = r.getCurrentLoggers();
Logger logger = null;
while(elogs.hasMoreElements())
//need to show the elements of teamcenter only.
logger = (Logger)elogs.nextElement();
hdm.addLoggerMBean(logger.getName());
} System.out.println(Logger.getRootLogger().getLevel().toString());
int portNumber=9999;
ObjectName htmlName = new ObjectName("log4j:logger=root,port=" + portNumber) ;
HtmlAdaptorServer html = new HtmlAdaptorServer(portNumber);
html.setPort(portNumber);
server.registerMBean(html, htmlName);
html.start();
app.go();
When setting the attributes for the appenders under log4j from htmladapter it gives the following message.
*477 All Attributes Not Set*
*1/8 attribute(s) were not set:*
appender%3DTaskAppender%2Clayout%3Dorg.apache.log4j.PatternLayout
Please advice how can we solve this issue ~Vilas
