Anynone knows if it is possible to deploy MBeans controlled by HASingletonController packaged as SAR, itself packaged with other modules inside an EAR deployed in farm?.
I am trying with no luck, but i am not sure what is the root of the problem, as JBoss docs says "If your service is an Mbean (i.e., not a J2EE deployment like an ear or war or jar), you can deploy it along with a service called an HASingletonController in order to turn it into an HA singleton".
This sentence is confusing me; only MBeans are services, right?. Then... whats the meaning.
The SAR jboss-service.xml is:
<server>
<mbean code="sample.SampleService"
name="sample:service=SampleService">
</mbean>
<!-- HASingletonController to run the above MBean as a singleton -->
<mbean code="org.jboss.ha.singleton.HASingletonController"
name="etrans:service=SampleController">
<depends>jboss:service=DefaultPartition</depends>
<depends>sample:service=SampleService</depends>
<attribute name="TargetName">sample:service=SampleService</attribute>
<attribute name="TargetStartMethod">startSingleton</attribute>
<attribute name="TargetStopMethod">stopSingleton</attribute>
</mbean>
</server>
The MBean extends ServiceMBeanSupport and has startSingleton/stopSingleton methods like the interface does. It acts as a HASingleton with the Barrier method but not with HASingletonController.
Thanks in advance
