[jboss-user] [Management, JMX/JBoss] - Deploy MBean service get No ClassLoaders found exception

[loseyourself]

Greetings all,

I am using JBoss 3.2.5 to implement a mail listener and deploy it as an MBean service. I follow the sample of HelloWorld mbean service tutorial on the wiki site,
1. create an interface:
public interface TopicMailListenerMBean extends ServiceMBean{
	public String getName();
	public void setName(String name);
	public String getUrl();
	public void setUrl(String url);
	public void disconnect() throws JMSException;
}
2. create mbean class:
public class TopicMailListener extends ServiceMBeanSupport 
	implements MessageListener, TopicMailListenerMBean {
                public void onMessage(Message msg) {...}
                ...
}
3. create a jboss-service.xml
<?xml version="1.0" encoding="UTF-8"?>

  
    10.65.240.244:1099
    topic/testTopic      

4. deploy the war to jboss, and rename it to .sar, the hirarche of the sar is:
test.sar
test.sar/META-INF/jboss-service.xml
test.sar/au/gov/nsw/community/mail/TopicMailListener.class
test.sar/au/gov/nsw/community/mail/TopicMailListenerMBean.class

Now, once I deploy the .sar in the JBOSSHOME/server/all/deploy, I always get following exceiption:
2007-07-18 12:33:05,640 DEBUG [org.jboss.system.ServiceCreator] About to create bean: au.gov.nsw.community.mail:service=TopicMailListener with code: au.gov.nsw.community.mail.TopicMailListener
