JBoss development, A new message was posted in the thread "Connection Problem": http://community.jboss.org/message/524417#524417 Author : Burak Eliaçık Profile : http://community.jboss.org/people/burakeliacik Message: -------------------------------------------------------------- Hi,   When i start my applicaion, the jboss throws an exception as below, but this exception is occured occasionally, i read http://docs.jboss.org/jbportal/v2.6.4/referenceGuide/html/wsrp.html#consu... documents and i reconfigure the wsrp producer and consumer, but it happens again. This error is the same with this one http://community.jboss.org/message/426224#426224, but in this thread member mentioned that "+the simplest is to delete portal-wsrp.sar"+ is this the only way to fix this problem. I try this fix but i met this problem again. What should i do? This issue is a configuration problem or what? Thank you for your interest.   Best Regards javax.management.MBeanException       at org.jboss.mx.interceptor.ReflectedDispatcher.handleInvocationExceptions(ReflectedDispatcher.java:180)       at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:163)       at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94)       at org.jboss.mx.interceptor.AbstractInterceptor.invoke(AbstractInterceptor.java:133)       at org.jboss.mx.server.Invocation.invoke(Invocation.java:88)       at org.jboss.mx.interceptor.ModelMBeanOperationInterceptor.invoke(ModelMBeanOperationInterceptor.java:142)       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.varia.scheduler.Scheduler$MBeanListener.handleNotification(Scheduler.java:1346)       at sun.reflect.GeneratedMethodAccessor48.invoke(Unknown Source)       at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)       at java.lang.reflect.Method.invoke(Unknown Source)       at org.jboss.mx.notification.NotificationListenerProxy.invoke(NotificationListenerProxy.java:153)       at $Proxy158.handleNotification(Unknown Source)       at javax.management.NotificationBroadcasterSupport.handleNotification(Unknown Source)       at javax.management.NotificationBroadcasterSupport$SendNotifJob.run(Unknown Source)       at javax.management.NotificationBroadcasterSupport$1.execute(Unknown Source)       at javax.management.NotificationBroadcasterSupport.sendNotification(Unknown Source)       at javax.management.timer.Timer.sendNotification(Unknown Source)       at javax.management.timer.Timer.notifyAlarmClock(Unknown Source)       at javax.management.timer.TimerAlarmClock.run(Unknown Source)       at java.util.TimerThread.mainLoop(Unknown Source)       at java.util.TimerThread.run(Unknown Source)   Caused by: org.jboss.portal.portlet.InvokerUnavailableException: Problem getting service description for producer self, please see the logs for more information.       at org.jboss.portal.wsrp.consumer.WSRPConsumerImpl.getPortlets(WSRPConsumerImpl.java:156)       at org.jboss.portal.portlet.federation.impl.FederatedPortletInvokerService.getPortlets(FederatedPortletInvokerService.java:90)       at org.jboss.portal.core.management.PortletDiscoveryService.processPortletDiscovery(PortletDiscoveryService.java:88)       at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)       at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)       at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)       at java.lang.reflect.Method.invoke(Unknown Source)       at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155)       ... 22 more   Caused by: java.io.IOException: Could not transmit message       at org.jboss.ws.core.client.RemotingConnectionImpl.invoke(RemotingConnectionImpl.java:210)       at org.jboss.ws.core.client.SOAPRemotingConnection.invoke(SOAPRemotingConnection.java:77)       at org.jboss.ws.core.CommonClient.invoke(CommonClient.java:337)       at org.jboss.ws.core.jaxrpc.client.CallImpl.invokeInternal(CallImpl.java:517)       at org.jboss.ws.core.jaxrpc.client.CallImpl.invoke(CallImpl.java:277)       at org.jboss.ws.core.jaxrpc.client.PortProxy.invoke(PortProxy.java:156)       at $Proxy223.getServiceDescription(Unknown Source)       at org.jboss.portal.wsrp.consumer.ProducerInfo.getUnmanagedServiceDescription(ProducerInfo.java:618)       at org.jboss.portal.wsrp.consumer.ProducerInfo.internalRefresh(ProducerInfo.java:303)       at org.jboss.portal.wsrp.consumer.ProducerInfo.detailedRefresh(ProducerInfo.java:254)       at org.jboss.portal.wsrp.consumer.ProducerInfo.refresh(ProducerInfo.java:249)       at org.jboss.portal.wsrp.consumer.ProducerInfo.getPortletMap(ProducerInfo.java:566)       at org.jboss.portal.wsrp.consumer.WSRPConsumerImpl.getPortlets(WSRPConsumerImpl.java:151)       ... 29 more   Caused by: org.jboss.remoting.CannotConnectException: Can not connect http client invoker.
