Hi, I am trying to make connection to the JBoss JMX service, JBoss is running on different machine than my host but in the same network. Trying to use RMIAdapter to connect. Follwoing is code I am trying: String providerUrl = "remote_host_name:1099"; Properties p = new Properties(); p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); p.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); p.setProperty(Context.PROVIDER_URL, providerUrl); p.setProperty(Context.SECURITY_PRINCIPAL, "admin"); p.setProperty(Context.SECURITY_CREDENTIALS, "admin"); InitialContext ic = new InitialContext(p); MBeanServerConnection server = (MBeanServerConnection) ic.lookup("jmx/invoker/RMIAdaptor"); System.out.println("server "+server); ObjectName Oname = new ObjectName("jboss.system:type=ServerInfo"); System.out.println("Host name: " + server.getAttribute(Oname, "HostName")); But I get follwoing exception: server org.jboss.invocation.jrmp.interfaces.JRMPInvokerProxy@82c01f java.lang.SecurityException: Failed to authenticate principal=null, securityDomain=WebSdkWebRealm at org.jboss.jmx.connector.invoker.AuthenticationInterceptor.invoke(AuthenticationInterceptor.java:97) at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.invocation.jrmp.server.JRMPProxyFactory.invoke(JRMPProxyFactory.java:179) 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:585) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) at org.jboss.invocation.jrmp.server.JRMPInvoker$MBeanServerAction.invoke(JRMPInvoker.java:819) at org.jboss.invocation.jrmp.server.JRMPInvoker.invoke(JRMPInvoker.java:420) 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:585) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:294) at sun.rmi.transport.Transport$1.run(Transport.java:153) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:149) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:466) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:707) at java.lang.Thread.run(Thread.java:595) at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(Unknown Source) at sun.rmi.transport.StreamRemoteCall.executeCall(Unknown Source) at sun.rmi.server.UnicastRef.invoke(Unknown Source) at org.jboss.invocation.jrmp.server.JRMPInvoker_Stub.invoke(Unknown Source) at org.jboss.invocation.jrmp.interfaces.JRMPInvokerProxy.invoke(JRMPInvokerProxy.java:133) at org.jboss.invocation.InvokerInterceptor.invokeInvoker(InvokerInterceptor.java:365) at org.jboss.invocation.InvokerInterceptor.invoke(InvokerInterceptor.java:197) at org.jboss.jmx.connector.invoker.client.InvokerAdaptorClientInterceptor.invoke(InvokerAdaptorClientInterceptor.java:66) at org.jboss.proxy.SecurityInterceptor.invoke(SecurityInterceptor.java:70) at org.jboss.proxy.ClientMethodInterceptor.invoke(ClientMethodInterceptor.java:74) at org.jboss.proxy.ClientContainer.invoke(ClientContainer.java:100) at $Proxy1.getAttribute(Unknown Source) at com.bmc.java.TestJbossConnection.connect(TestJbossConnection.java:38) at com.bmc.java.TestJbossConnection.main(TestJbossConnection.java:103) If the JBoss server is running on my host machine, then this works. I get the server information. Does any one know what am I missing here. But I haven't set any credentials for the JBoss server. Please help.
