ClassCastException when receiving serviceNames attribute of Catalina:type=Server mbean -------------------------------------------------------------------------------------- Key: JBAS-4150 URL: http://jira.jboss.com/jira/browse/JBAS-4150 Project: JBoss Application Server Issue Type: Bug Security Level: Public (Everyone can see) Reporter: Nikolay Chugunov ClassCastException thrown when receiving serviceNames attribute of Catalina:type=Server mbean. To reproduce start JBoss AS server with jmx connector as described at http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossMBeansInJConsole Run following test: import javax.management.*; import javax.management.remote.*; public class CatalinaMBeanTest { public static void main(final String[] args) throws Exception { final JMXServiceURL url = new JMXServiceURL( "service:jmx:rmi:///jndi/rmi://127.0.0.1:1099/jmxrmi"); final MBeanServerConnection conncetion = JMXConnectorFactory.connect( url, null).getMBeanServerConnection(); conncetion.getAttribute(new ObjectName("Catalina:type=Server"), "serviceNames"); } } Output: Exception in thread "main" javax.management.RuntimeOperationsException: Exception invoking method serviceNames at org.apache.commons.modeler.BaseModelMBean.getAttribute(BaseModelMBean.java:353) at org.jboss.mx.server.RawDynamicInvoker.getAttribute(RawDynamicInvoker.java:117) at org.jboss.mx.server.MBeanServerImpl.getAttribute(MBeanServerImpl.java:556) at org.jboss.system.server.jmx.LazyMBeanServer.getAttribute(LazyMBeanServer.java:250) at javax.management.remote.rmi.RMIConnectionImpl.doOperation(RMIConnectionImpl.java:1401) at javax.management.remote.rmi.RMIConnectionImpl.access$200(RMIConnectionImpl.java:72) at javax.management.remote.rmi.RMIConnectionImpl$PrivilegedOperation.run(RMIConnectionImpl.java:1262) at javax.management.remote.rmi.RMIConnectionImpl.doPrivilegedOperation(RMIConnectionImpl.java:1357) at javax.management.remote.rmi.RMIConnectionImpl.getAttribute(RMIConnectionImpl.java:598) at sun.reflect.GeneratedMethodAccessor110.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:305) at sun.rmi.transport.Transport$1.run(Transport.java:159) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:155) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:535) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:790) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:649) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:255) at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:233) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:142) at com.sun.jmx.remote.internal.PRef.invoke(Unknown Source) at javax.management.remote.rmi.RMIConnectionImpl_Stub.getAttribute(Unknown Source) at javax.management.remote.rmi.RMIConnector$RemoteMBeanServerConnection.getAttribute(RMIConnector.java:863) at CatalinaMBeanTest.main(CatalinaMBeanTest.java:17) Caused by: java.lang.ClassCastException: org.jboss.web.tomcat.tc5.StandardService cannot be cast to org.apache.catalina.core.StandardService at org.apache.catalina.core.StandardServer.getServiceNames(StandardServer.java:487) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 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.apache.commons.modeler.BaseModelMBean.getAttribute(BaseModelMBean.java:346) at org.jboss.mx.server.RawDynamicInvoker.getAttribute(RawDynamicInvoker.java:117) at org.jboss.mx.server.MBeanServerImpl.getAttribute(MBeanServerImpl.java:556) at org.jboss.system.server.jmx.LazyMBeanServer.getAttribute(LazyMBeanServer.java:250) at javax.management.remote.rmi.RMIConnectionImpl.doOperation(RMIConnectionImpl.java:1401) at javax.management.remote.rmi.RMIConnectionImpl.access$200(RMIConnectionImpl.java:72) at javax.management.remote.rmi.RMIConnectionImpl$PrivilegedOperation.run(RMIConnectionImpl.java:1262) at javax.management.remote.rmi.RMIConnectionImpl.doPrivilegedOperation(RMIConnectionImpl.java:1357) at javax.management.remote.rmi.RMIConnectionImpl.getAttribute(RMIConnectionImpl.java:598) at sun.reflect.GeneratedMethodAccessor110.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:305) at sun.rmi.transport.Transport$1.run(Transport.java:159) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:155) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:535) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:790) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:649) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) Tested under JBoss4.0.5 GA, Java 1.6, Linux -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
