Hi Peter, There aren't any docs for configuring CMP beans on OpenEJB's site yet. As you noticed, we are using castor in our CMP container, all cmp config files are all castor controlled files. You should be able to get information on Castor's mapping files on their website (www.castor.org). There is no difference between configuring an entity bean than with any other java object, so anything you learn about Castor's config files will be applicable. I would hop onto their mailing list if you have trouble with the syntax of the Castor config files.
On the topic of Stubs and Ties, we have a server (an adapter really) that can make beans accessible over a CORBA ORB. If you use that, you do need stubs and ties (a tie is like a skeleton). We don't support it or test on it at the moment as it is being completely re-written. I say it's more of an adapter because it just consists of a little glue to allow you to embed OpenEJB inside OpenORB. OpenORB is really the "server", not our glue. Again, it's being re-written. OpenEJB is a container system that can be plugged or adapted into other products or server. We have three server implementations of our own so far. Local Server (aka IntraVM) -- Allows clients in the same VM to access the container system directly. This is a mandatory server as it is what we use when one bean accesses other beans. It also supports non-bean access, so you can use it in your applications when you want to run OpenEJB in the same container system. This "server" is over two years old. Remote Server -- Allows people to run OpenEJB as a standalone server and access beans remotely over a network. When you use the "openejb start" command, you are starting the Remote Server. This server uses dynamically generated proxies, so no stubs or ties are required on the server or client sides. CORBA Adapter -- Exports remote and home interfaces as Stubs and Ties into a CORBA ORB implementation. Currently only supports OpenORB, but the whole thing is being re-written to perform better and be capable of using any valid ORB implementation. It does require stub and tie classes on the server and client sides. It uses the RMI-IIOP protocol to communicate over the network. An interesting note, when you use the deploy command, it deploys the bean into the container system itself. You can then access the bean through the any of the servers above.
