Exposing MBeans with Spring

Published by Gilles at 9:21 pm under J2EE, Java, Spring

Using JDK 5.0 Annotations

An other way to expose Mbeans is to use the JDK5 annotations.
provides a set of annotations that mirror the Commons Attribute attribute classes and an implementation of the JmxAttributeSource strategy interface, the AnnotationsJmxAttributeSource class, that allows the MBeanInfoAssembler to read them.

Putting all together

    Hello, I found your post about the Spring mbeans in the WebSphere 6.1. I am new to Spring and JMX and looking for a step by step guide to register and calling by wsadmin some Spring’s mbeans provided by the app developer. I read your post and do understand the websphere naming strategy but where do I need to place this class WebsphereNamingStrategy ?

    Hello Mark,
    You can place your WebsphereNamingStrategy class where you want. For my part, I place it in an “util” package…
    Cheers,
    Gilles

    Hello Gilles,
    Thanks a lot for a quick response. I just have one question if there is any possibility to enable the Spring’s mbean in WAS 6.1 without adding any new code to the project ? I do not have the source code and do not want to extend the EAR file.

    excellent info, thanks!
    was trying to get this running on websphere and also figured out that websphere changes the objectnames of the mbeans..your sources saved a lot of time for me yeehaa :-)
