Namespace federation

Federating namespaces involves binding contexts from one namespace into another namespace.

For example, assume that a namespace, Namespace 1, contains a context under the name a/b. Also assume that a second namespace, Namespace 2, contains a context under the name x/y. (See the following illustration.) If context x/y in Namespace 2 is bound into context a/b in Namespace 1 under the name f2, the two namespaces are federated. Binding f2 is a federated binding because the context associated with that binding comes from another namespace. From Namespace 1, a lookup of the name a/b/f2 returns the context bound under the name x/y in Namespace 2. Furthermore, if context x/y contains an enterprise bean (EJB) home bound under the name ejb1, the EJB home can be looked up from Namespace 1 with the lookup name a/b/f2/ejb1. Notice that the name crosses namespaces. This fact is transparent to the naming client.
