It seems that this class was removed from the portal-common-lib.jar. Is there an alternative class or configuration to use? I get this error using the example in the user manual: | 10:29:30,718 ERROR [MainDeployer] Could not create deployment: file:/C:/portal/jboss-portal/server/default/deploy/query-portlet.sar | org.jboss.deployment.DeploymentException: No ClassLoaders found for: org.jboss.portal.common.system.JBossServiceModelMBean; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: org.jboss.portal.common.system.JBossServiceModelMBean) | at org.jboss.system.ServiceConfigurator.install(ServiceConfigurator.java:196) | at org.jboss.system.ServiceController.install(ServiceController.java:226) | at sun.reflect.GeneratedMethodAccessor87.invoke(Unknown Source) | 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.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:210) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981789#...
