I like the mbean browser, I use it for introspecting my application sometimes. A typical application for this could be an event driven server application, say an exchange simulator. So in this case it is not running in a container.
But there is one thing that is cumbersome in the development usecase I had. If the process is restarted (which in my case was frequently) there are many steps to get back to view the beans.
Ideally I would like to say "reconnect when possible" on a connection, and keep (but shade) the view when connection is lost, and bring it back up when possible.
