I'm not sure I understand your question.If you meant the particular use of the pattern with JNDI lookup, that has been replaced by the DI (Dependency Injection) pattern in EJB 3.0.

As opposed to using it with remote EJBs?

Here's the [url=http://java.sun.com/blueprints/code/jps131/src/com/sun/j2ee/blueprints/servicelocator/web/ServiceLocator.java.html] Sun blueprints implementation [/url] of the pattern.

Notice the difference between getLocalHome(.) vs. getRemoteHome(.).
