The Business Delegate design pattern can be applied to provide a connection to any business objects, not only those implemented using Enterprise JavaBeans. In general, object-oriented design patterns are not dependent upon any particular implementation technologies, e.g. EJB, JMS, Java Servlets, etc. The examples typically provided with design pattern documentaiton are only examples, they are not rules or restrictions.

This is really a trivial concept. I wouldn't think that an author would write about something so simple. The nature of object-oriented design patterns is sufficient enough to grasp the various possibilities of implementations. If you can understand their nature, then you can clearly understand how to use them.
 
It is sorta covered in the JavaRanch Style Guide.
