We're going to embed OpenEJB3 into a plain JUnit TestCase as a simple means of demonstrating the remote capabilities. We'll do the embedding in our test setUp method, then will make two test methods:

• one for invoking the bean's remote interface via the LocalInitialContextFactory which goes straight against the embedded container system

...

• one for invoking the bean's remote interface via the RemoteInitialContextFactory which connects to a Socket and communicates to the embedded container system over the ejbd protocol.

LocalInitialContextFactory: making in-vm calls to a remote business interface

RemoteInitialContextFactory: making networked calls to a remote business interface

This is the part you would want to do in apps that are running a different VM than the one in which the ejb container is embedded. These "client" VMs need only have the the openejb-client jar in their classpath and connect to OpenEJB via the RemoteInitialContextFactory like any other remote EJB client.
