JMX error??

[eolith]

Hello, I have a Tomcat 5.5 with Alfresco 3 Labs. I'm trying to configure a cluster, but I'm currently trying a single server. When I deploy my alfresco.war, I get this error:

18:44:30,821  ERROR [[Catalina].[localhost].[/alfresco]] Excepción enviando evento inicializado de contexto a instancia de escuchador de clase org.alfresco.web.app.ContextListener

Try to change the server once again. If you get the same error again just post what kind of error you get exactly.
