[jboss-user] [Messaging, JMS & JBossMQ] - Deploy Message listener as MBean service get No ClassLoaders

[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"?> 
< server> 
< mbean code="au.gov.nsw.community.mail.TopicMailListener" name="au.gov.nsw.community.mail:service=TopicMailListener"> 
< attribute name="Url">10.65.240.244:1099< /attribute> 
< attribute name="Name">topic/testTopic< /attribute> 
< /mbean> 
< /server>

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

Could anybody tell me where is wrong? I do appreciate for any help in advance!
