beginners question about MBeans

[mglowacki]

Hi

I would like to have a preview in runtime, how many users are currently on site. I have session scoped bean, named SessionData, which is created for each customer that visit the site. Now I would like to see how many instances are created, I suppose I could use MBeans and JMX console for that?

What I expect with this thread is an answer if I'm right, and if, please give a link if you have, to tutorial how to do it without going deeply into mbean's topics - I know it's interesting thing, but now I have enough problems with my app performance and need quick solution to measure page load :(

Thanks in advance,
Michal

I am a little confused as you are posting about MBeans but seem to be talking about a Session Bean.

If you have an MBean or a Service Bean, you only have one instance of this bean.

If you are using a Session Bean, sorry, no idea.
But I would also love to hear if this is possible.
