Hi, I changed jboss server port number from 8080 to 8081. I am not sure whether this is correct. I changed the port number in the server/all/jbossweb.sar/server.xml and jbossws.sar/META-INF/jboss-beans.xml file. And I also have the following errors in the server log file after restarted jboss server: .... 2008-08-25 04:50:48,257 DEBUG [org.jboss.web.tomcat.service.deployers.TomcatDeployment] (main) Creating ENC using ClassLoader: BaseClassLoader@2fcb4f{vfsfile:/root/jboss/jboss-5.0.0.CR1/server/default/deploy/jmx-console.war/} 2008-08-25 04:50:48,279 DEBUG [org.jboss.web.tomcat.service.deployers.TomcatDeployment] (main) Unable to retrieve orb javax.management.InstanceNotFoundException: jboss:service=CorbaORB is not registered. at org.jboss.mx.server.registry.BasicMBeanRegistry.get(BasicMBeanRegistry.java:529) at org.jboss.mx.server.MBeanServerImpl.getAttribute(MBeanServerImpl.java:559) at org.jboss.web.tomcat.service.deployers.TomcatDeployment$EncListener.lifecycleEvent(TomcatDeployment.java:496) ..... .... 2008-08-25 04:55:17,835 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] (Thread-12) Periodic recovery - first pass <Mon, 25 Aug 2008 04:55:17> 2008-08-25 04:55:17,835 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] (Thread-12) StatusModule: first pass 2008-08-25 04:55:17,835 DEBUG [com.arjuna.ats.txoj.logging.txojLoggerI18N] (Thread-12) [com.arjuna.ats.internal.txoj.recovery.TORecoveryModule_3] - TORecoveryModule - first pass 2008-08-25 04:55:17,836 DEBUG [com.arjuna.ats.jta.logging.loggerI18N] (Thread-12) [com.arjuna.ats.internal.jta.recovery.info.firstpass] Local XARecoveryModule - first pass 2008-08-25 04:55:27,839 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] (Thread-12) Periodic recovery - second pass <Mon, 25 Aug 2008 04:55:27> 2008-08-25 04:55:27,840 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] (Thread-12) AtomicActionRecoveryModule: Second pass 2008-08-25 04:55:27,840 DEBUG [com.arjuna.ats.txoj.logging.txojLoggerI18N] (Thread-12) [com.arjuna.ats.internal.txoj.recovery.TORecoveryModule_6] - TORecoveryModule - second pass 2008-08-25 04:55:27,840 DEBUG [com.arjuna.ats.jta.logging.loggerI18N] (Thread-12) [com.arjuna.ats.internal.jta.recovery.info.secondpass] Local XARecoveryModule - second pass 2008-08-25 04:57:27,847 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] (Thread-12) Periodic recovery - first pass <Mon, 25 Aug 2008 04:57:27> 2008-08-25 04:57:27,847 DEBUG [com.arjuna.ats.arjuna.logging.arjLogger] (Thread-12) StatusModule: first pass 2008-08-25 04:57:27,848 DEBUG [com.arj How to fix the errors?
