[jboss-user] [Management, JMX/JBoss] - Persistence not quite working
Hello,
I have two XMBeans which attributes I'd like to persist. My problem is that while the
first MBean persists its attributes, the second doesn't. After couple of hours I found
out that the difference between the two XMBeans is that the attributes for the first one(
which is a configuration bean) are ?read-write? and when I press ?Apply Changes? button
from the JMX console, the values are saved as per the ?xmbean.xml file. The attributes of
the second one are ?read-only?, as I update them using a different mechanism. This results
in the attribute values not being saved. I added a setter to one of the attributes( just
to prove that this is indeed the reason) and once I updated this attribute by clicking on
the ?Apply changes? button, the value was saved and the next time I re-started the server
I was able to see the correct value.
My question is ? is this a bug and is there a way to work around this problem?
To illustrate the problem I added extracts from my code
stats-xmbean.xml
