Simple Spring Question.

[anagha]

Hi All,
I'm newbie to Spring.
Say, bean xml is loaded and I get application context.
After this if I want to change the bean definition. Is it possible?
If yes, how?
This is particulary required when my bean is "quartz.JobDetailBean" and I need to change the parameters to poll a device dynamically. say interval, repeatCount etc.)

Any help is appreciated.
thanks,
anagha

Just an idea -- what if you implement your Spring bean as a JMX MBean, which can be modified on the fly? Then you can access your MBean via a JMX Agent (such as in JBoss) and modify the MBean's properties while it is running. I've never done this with Spring, but I imagine that it can be done.

I hope this helps...

Of course, since a spring managed bean is still a bean, you can just change its properties at any time, especially a non-singleton.

The problem is if this bean is part of "wiring" inside the context, how will dependent beans be updated or refreshed. One can use the method shown here http://forum.springframework.org/showthread.php?t=12401

Another problem is that any changes to a bean definition's properties are not persisted directly by Spring yet.
