Hi,
i just installed weblogic workshop 8.1 and i wanted to start creating a simple EJB application. After creating a simple (express) Basic Weblogic Platform Domain, when I create an application ans try to start the server, I get the error listed below. Can anyone let me know what I'm missing in the initial configuration?

Thanks.
