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!
