    Retrieving properties of an MBean

    Ice Man Newbie

      I have the QuartzService MBean deployed on JBoss and I wanted to retrieve the MBean's properties that were loaded from the deployment file. Is there a clean way of doing this?

          Please if anybody could point me in the right direction I would be very grateful. I know the JMX console is able to retrieve all the MBeans and displays all their properties through the web console. I just want to know how to do this, any information about this would really help thank you.

            Thanks Peter for your reply it was extremely helpful. However now I am getting an exception saying that the Context is not readable. I guess for security reasons, but is there a way around this? I couldn't find it on the link you provided. Thanks again, below is the exception I get

              If the property is marked as write only, there is no way to read it. Use the jmx-console to determine the read or write-ability of the property you are interested in.
