[jboss-user] [JBoss Portal] - Can't load CMS portlet after change datasource

Hi, I am trying to deploy jboss-portal to use oracle 10g. After setting up the portal-oracle-ds at jboss/default/deploy, get this error that cms cannot deploy as below. | 15:37:02,809 INFO [JackrabbitJCRService] Repository 'PortalRepository' created | 15:37:02,840 INFO [JackrabbitJCRService] The repository does not know about CMS | node types | 15:37:02,856 INFO [JackrabbitJCRService] Creating CMS nodeTypes. | 15:37:02,856 WARN [ServiceController] Problem starting service portal:service=C | MS | javax.jcr.NamespaceException: failed to register namespace portalcms -> http://j | boss.org/jcr/portalcms: mapping already exists | at org.apache.jackrabbit.core.NamespaceRegistryImpl.registerNamespace(Na | mespaceRegistryImpl.java:287) | at org.jboss.portal.cms.impl.jcr.jackrabbit.JackrabbitJCRService.registe | rCustomNodeTypes(JackrabbitJCRService.java:183) | at org.jboss.portal.cms.impl.jcr.jackrabbit.JackrabbitJCRService.start(J | ackrabbitJCRService.java:111) | at org.jboss.portal.cms.impl.jcr.JCRCMS.startJCR(JCRCMS.java:302) | at org.jboss.portal.cms.impl.jcr.JCRCMS.startService(JCRCMS.java:267) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanS | upport.java:289) | at org.jboss.system.ServiceMBeanSupport.start(ServiceMBeanSupport.java:1 | 96) | at org.jboss.portal.jems.as.system.AbstractJBossService.start(AbstractJB | ossService.java:73) | at sun.reflect.GeneratedMethodAccessor22.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAcces | sorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:597) | at org.jboss.portal.jems.as.system.JBossServiceModelMBean$ServiceMixin.e | xecute(JBossServiceModelMBean.java:486) | at org.jboss.portal.jems.as.system.JBossServiceModelMBean$ServiceMixin.s | tartService(JBossServiceModelMBean.java:452) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanS | upport.java:289) | | I also follow an advise on similar problem at this link below by deleting the default/data directory, but still can't solve it. http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981263#...
