    One slight problem with Chapter 2 - it talks about the JMX 1.0.1 RI, whereas java.sun.com has the 1.1 RI.

    There may be substantial differences, enough to make ch 2 pretty much unusable. I'll give it a bash anyway, though.

    I just fitted a basic JMX interface onto my current app, using the examples in this chapter as a temnplate. Very, very easy to do. Using the supplied HTML adapter, it's surprisingly powerful.

    Impressed so far.

    So what am I missing? I still haven't found anything that shows me who fit it into an existing app.

    There's enough in chapter 2 to get you going.

    What I've done is embed an MBeanServer inside my app, and written a handful of simple MBeans which call existing methods within my app (e.g. set a debug flag). The beans are then exposed using the HTML adapter.

    That is what I thought. It never really says how to use it so I wasn't sure. I'm not using EJBs so using JNDI doesn't help. I have standard java classes that are used by servlets. I don't want to restart the 'web apps' but I do need to dynamically change parameters or tell the class to reload the properties (which is not good because the class has an object not a path).

    I'll give this a shot.

    Which JMX implementation are you using? I've downloaded IBM's the opensource one and Sun's - mostly looking for clues.

    Thanks,
    Mark

    I'm just using the Sun reference implementation. The only sun-specific class I've used so far is the HtmlAdapterServer.

    The MBean you created - Does that control your class or does your class implement the interface and is the MBean?

    I made no changes to the app's existing classes. I have a seperate JMX package which contains the MBeans, which pull the existing strings in the app.

    I must be getting dense in my 'old' age. I don't see anywhere in the book (or anywhere else) that shows me how to do this. This is what I need to be able to do.
