Hello I have just downloaded jboss: jboss-4.2.3.GA after unpacking I started server with jdk 1.5 I run default config and see a number of exceptions in log, for example: org.jboss.deployment.DeploymentException: Trying to install an already registered mbean: jboss.remoting:type=Connector,name=DefaultEjb3Connector,handler=ejb3 org.jboss.deployment.DeploymentException: Trying to install an already registered mbean: jboss.aop:service=AspectManager org.jboss.deployment.DeploymentException: Trying to install an already registered mbean: jboss.bean:service=JBossBeanDeployer I see these errors in standard, default jboss instance, before adding any of my code. Could you tell me how can I resolve them and why do the appear? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4189681#...
