Hi, I am using JMSServerControl.createQueue() to create queues on the fly (programatically) as discussed in http://www.jboss.org/index.html?module=bb&op=viewtopic&t=157444. This works fine and the API creates the Queue or just binds the queue to JNDI if queue already exists. However, this fails as soon as there are any messages paged in the Queue. i.e. If I am trying to use this API for a Queue which already exists and has some messages paged, subsequent calls to this API fails with following Exception. Any help would be highly appreciated. java.lang.Exception: did not receive reply for message org.jboss.messaging.core.client.impl.ClientMessageImpl@18e613d | at org.jboss.messaging.core.management.impl.ReplicationOperationInvokerImpl.invoke(ReplicationOperationInvokerImpl.java:115) | at org.jboss.messaging.core.management.jmx.impl.ReplicationAwareStandardMBeanWrapper.replicationAwareInvoke(ReplicationAwareStandardMBeanWrapper.java:75) | at org.jboss.messaging.jms.server.management.jmx.impl.ReplicationAwareJMSServerControlWrapper.createQueue(ReplicationAwareJMSServerControlWrapper.java:499) | 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 com.sun.jmx.mbeanserver.StandardMetaDataImpl.invoke(StandardMetaDataImpl.java:414) | at javax.management.StandardMBean.invoke(StandardMBean.java:323) | at com.sun.jmx.mbeanserver.DynamicMetaDataImpl.invoke(DynamicMetaDataImpl.java:213) | at com.sun.jmx.mbeanserver.MetaDataImpl.invoke(MetaDataImpl.java:220) | at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.invoke(DefaultMBeanServerInterceptor.java:815) | at com.sun.jmx.mbeanserver.JmxMBeanServer.invoke(JmxMBeanServer.java:784) | at javax.management.remote.rmi.RMIConnectionImpl.doOperation(RMIConnectionImpl.java:1410) | at javax.management.remote.rmi.RMIConnectionImpl.access$100(RMIConnectionImpl.java:81) | at javax.management.remote.rmi.RMIConnectionImpl$PrivilegedOperation.run(RMIConnectionImpl.java:1247) | at javax.management.remote.rmi.RMIConnectionImpl.doPrivilegedOperation(RMIConnectionImpl.java:1343) | at javax.management.remote.rmi.RMIConnectionImpl.invoke(RMIConnectionImpl.java:784) | at sun.reflect.GeneratedMethodAccessor27.invoke(Unknown Source) | 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) Thanks Bijith View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4247150#...
