Hello,

I'm within the migration process of our application from JBoss v5.1 to JBoss v7.1.1.

After what I updated our MBeans codes to MXBeans I have a problem with adding descriptions (metadata) to our MXBean interfaces via standard java annotations.

Same code was working fine in JBoss v5.1 and adds important description for MBean's operations/parameters to MBeanInfo.

Such MBean description was then displayed in javax.management tools like JConsole or JMX Console so it is very useful.

Here is a sample from our source codes:

Sample MXBean Interface:

@MXBean(true)

@Description("Some nice description of whole MXBean")

@Local

public interface XYMXBean {

    @Description("Some nice description of MXBean operation")

    String performSomeExecution(@PName("nicePrameterName") String parameterName);

}

Sample MXBean Impl:

@Singleton

@Startup

public class XYMBeanImpl implements XYMXBean {

    private static final String MXBEAN_OBJECT_NAME = "com.abc.def:service=XY";

    private static Log logger = LogFactory.getLog(XYMBeanImpl.class);

    private ObjectName objectName;

    @PostConstruct

    public void registerInJMX() {

    logger.debug("Registering MXBean: " + MXBEAN_OBJECT_NAME);

    this.objectName = MBeanHelper.registerInJMX(this, MXBEAN_OBJECT_NAME);

    }

    @PreDestroy

    public void unregisterFromJMX() {

    logger.debug("Unregistering MXBean: " + objectName.getCanonicalName());

    MBeanHelper.unregisterFromJMX(objectName);

    }

    @Override

    public String performSomeExecution(String parameterName) {

     // do some business logic

    }

}

Notes:

1. MXBeans are correctly registered in MBean Server, I can see them and I can invoke their operations successfully
2. @PName is very similar to @Description, it is different only with @Target({ElementType.PARAMETER}).
3. In JBoss v5.1 we defined MBeans via org.jboss.ejb3.annotation.Service, but since this annotation was removed, I migrated the codes to @MXBean and EJB3.1 as described in my sample code.

Such @Description and @PName annotations were working in JBoss v5.1, but now in JBoss v7.1 these annotations doesn't fill MBeanInfo with provided description content.

Am I wrong with my code or is there some known limitation I'm not aware of?

Thanks a lot for any hint.
