Stale values MBean attributes
I'm creating my own user interface for interacting with Camel routes via
JMX. I seem to have a "delay" problem when reading these attributes. E g
when reading the "ExchangesCompleted" attribute, it takes a while (> 1
minute) after an exchange is completed before this value is incremented.
When reading the value via the JConsole, the value is immediately updated
(after I press the "refresh" button) meaning that I must be doing something
wrong when accessing the JMX attribute. Can someone enlighten me as to what
is going on and how I can make sure that I read the latests (up-to-date)
value. E g , is there a "refresh" method I can call from my code?
/Bengt

It seems Iike the delay I encountered was due to problems on the client side
that I have now resolved.

Thanks for your reply Claus. However, I've really tried to Google about this
and I haven't managed to find out how this works. If anyone has a hint I
would really appreciate it.

I think there is some general JMX "refresh" or "delay" interval which
can be set to indicate how often the JMX attributes updates are
visible.
Try to google about about this.
