No extra ports necesarry. Simply point your EJB client to the URL of the LoaderSerlvet and go! All HTTP requests to the LoaderServlet will be sent into the embedded OpenEJB container. Combine this with the Collapsed EAR approach to embedding OpenEJB and you get a single webapp containing it's own private EJBs and OpenEJB container which can now support it's own remote java clients as well as web browsers. Or combine this with traditional style of embedding OpenEJB into the root of Tomcat at a global level and turn your Tomcat server into a no holds-barred EJB server. If you want no remoting at all, simply remove the LoaderServet's serlvet-mapping and the door is closed.
