I'm trying to debug this failure in the 4.2.0 testsuite: Suite: org.jboss.test.cluster.test.HASingletonElectionPolicyTestCase(Default-UDP) Test: testElectionPolicy Type: error Exception: javax.management.InstanceNotFoundException Message: jboss.examples:service=HASingletonMBeanExample_1 is not registered. In the server.log, I'm seeing this: ---------------------------------- 10:03:57,801 INFO [ServiceConfigurator] Problem configuring service jboss.examples:service=HASingletonMBeanExample-HASingletonController_1 org.jboss.deployment.DeploymentException: No Attribute found with name: HASingletonElectionPolicyMBean ---------------------------------- This is why the tests are failing. The thing that I'm stuck with is that the HASingletonElectionPolicyMBean class in question is present in jbossha.jar: ---------------------------------- [root@dhcp83-138 META-INF]# jar -tvf /var/lib/jbossas/server/cluster-UDP-0/lib/jbossha.jar | grep HASingletonElectionPolicyMBean 257 Mon Mar 19 19:01:36 EDT 2007 org/jboss/ha/singleton/HASingletonElectionPolicyMBean.class ---------------------------------- But - I guess that there is an attribute with the same name (HASingletonElectionPolicyMBean) defined where? Can anyone suggest how to debug this this? Thanks, Len DiMaggio ldimaggi(a)redhat.com View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4031608#...
