Hello,
your Alfresco Repository is not properly started up as it fails to export a specific service via RMI. This may be due to port conflicts on your machine - I have seen it happen when my Outlook already grabbed and blocked a port requires by the JMX services (default range 50500 - 50508).
You need to fix the following exception:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'avmRemoteService' defined in class path resource [alfresco/remote-services-context.xml]: Invocation of init method failed; nested exception is java.rmi.server.ExportException: internal error: ObjID already in use
Try running netstat -a to check for used ports before you attempt to start Alfresco and check for ports in the above range. If one of them is used, try identifying the relevant process and shut it down if possible or reassign the ports.
Regards
Axel
