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
