Global JNDI context versus local JNDI context

Using the global JNDI context to obtain EJB references is a perfectly valid, feasible approach with Application Server 8.2. Nonetheless, it is preferable to stay as close as possible to the J2EE specification, and retrieve EJB references through the local JNDI context of EJB client applications. When using the local JNDI context, you must first declare EJB resource references in the deployment descriptor of the client part (web.xml for a Web application, ejb-jar.xml for an EJB component).
