Sometimes when I stop or restart one of them I get following error: ERROR [  ] [org.springframework.scheduling.support.MethodInvokingRunnable] Invocation of method 'myMethod' on target class [class MyClass] failed org.springframework.jmx.access.InvalidInvocationException: jboss.ha:service=HASingletonDeployer is not registered.         at org.springframework.jmx.access.MBeanClientInterceptor.doInvoke(MBeanClientInterceptor.java:445)         at org.springframework.jmx.access.MBeanClientInterceptor.invoke(MBeanClientInterceptor.java:353)         at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:172)         at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:202)         at $Proxy323.isMasterNode(Unknown Source)         at ... sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)         at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)         at java.lang.reflect.Method.invoke(Method.java:597)         at org.springframework.util.MethodInvoker.invoke(MethodInvoker.java:273)         at org.springframework.scheduling.support.MethodInvokingRunnable.run(MethodInvokingRunnable.java:65)         at org.springframework.scheduling.support.DelegatingErrorHandlingRunnable.run(DelegatingErrorHandlingRunnable.java:51)         at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441)         at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:317)         at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:150)         at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$101(ScheduledThreadPoolExecutor.java:98)         at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeriodic(ScheduledThreadPoolExecutor.java:181)         at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:205)         at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)         at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)         at java.lang.Thread.run(Thread.java:619) "myMethod" is a method which is activated every 10 seconds and I check thereif my jboss is a maaster node (I am using HA-Singleton). I check this using something like isMasterNode() on HASingletonMBean. I will be grateful for any help. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632924#632924] Start a new discussion in Clustering Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
