I have not included the setting for transaction support in my TreeCacheAop configuration because I have been getting errors when using the TransactionManagerLookupClass attribute, with either DummyTransactionManagerLookup or TransactionManagerLookup as this attribute's value. I now expect that this absence of transaction support is why I do not get replication with the TreeCacheAop.
When I use the TransactionManagerLookup class for this attribute's value | <attribute name="TransactionManagerLookupClass">org.jboss.cache.TransactionManagerLookup</attribute> | I get the following Exception: | 09:28:28,845 ERROR [TreeCacheAop] Starting failed jboss.cache:service=TreeCacheAop | | java.lang.InstantiationException: org.jboss.cache.TransactionManagerLookup | | at java.lang.Class.newInstance0(Class.java:335) | at java.lang.Class.newInstance(Class.java:303) | at org.jboss.cache.TreeCache.startService(TreeCache.java:1089) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:272) | at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:222) | at sun.reflect.GeneratedMethodAccessor4.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:144) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:80) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:72) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:249) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:642) | at org.jboss.system.ServiceController$ServiceProxy.invoke(ServiceController.java:891) | at $Proxy0.start(Unknown Source) | | etc... | When I use the DummyTransactionManagerLookup class (the original setting in the example syncRepl.xml) for this attribute's value | <attribute name="TransactionManagerLookupClass">org.jboss.cache.TransactionManagerLookup</attribute> | I get the following Exception: | 09:37:22,322 ERROR [DummyTransactionManager] binding of DummyTransactionManager failed | | javax.naming.NameAlreadyBoundException | | at org.jnp.server.NamingServer.bind(NamingServer.java:126) | at org.jnp.interfaces.NamingContext.bind(NamingContext.java:501) | at org.jnp.interfaces.NamingContext.bind(NamingContext.java:469) | at javax.naming.InitialContext.bind(InitialContext.java:359) | at org.jboss.cache.transaction.DummyTransactionManager.getInstance(DummyTransactionManager.java:41) | at org.jboss.cache.DummyTransactionManagerLookup.getTransactionManager(DummyTransactionManagerLookup.java:17) | at org.jboss.cache.TreeCache.startService(TreeCache.java:1094) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:272) | at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:222) | at sun.reflect.GeneratedMethodAccessor4.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:144) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:80) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:72) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:249) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:642) | at org.jboss.system.ServiceController$ServiceProxy.invoke(ServiceController.java:891) | at $Proxy0.start(Unknown Source) | at org.jboss.system.ServiceController.start(ServiceController.java:416) | | etc... | One item of interest is that the TreeCacheAop still deploys OK when this error happens, in contrast to the failure to deploy which happens as a result of using the TransactionManagerLookup class for this attribute's value. Any ideas on what causes these errors and/or how to get around them ?
