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 <!DOCTYPE mbean PUBLIC | "-//JBoss//DTD JBOSS XMBEAN 1.0//EN" | "http://www.jboss.org/j2ee/dtd/jboss_xmbean_1_0.dtd"> | | <mbean> | <description></description> | | <descriptors> | <persistence persistPolicy="OnUpdate" | persistPeriod="10" | persistLocation="${jboss.server.data.dir}" | persistName="StatsJNDIMap.ser"/> | <currencyTimeLimit value="10"/> | <state-action-on-update value="keep-running"/> | <persistence-manager value="org.jboss.mx.persistence.ObjectStreamPersistenceManager" /> | </descriptors> | | <class>org.jboss.test.jmx.xmbean.JNDIMap</class> | | <constructor> | <description>The default constructor</description> | <name>JNDIMap</name> | </constructor> | | | <!-- Attributes --> | | <attribute access="read-write" getMethod="getStartDate" setMethod="setStartDate"> | <description>Start Date</description> | <name>Start Date</name> | <type>java.lang.String</type> | </attribute> | | | <attribute access="read-only" getMethod="getInBoxReqCount" > | <description>Number of requests</description> | <name>Get Message Requests</name> | <type>java.lang.String</type> | | </attribute> | | ... more | StatsXMBean.java public class StatsXMBean extends ServiceMBeanSupport | { | ... more | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008416#...
