For entity beans and session beans, this value specifies the global JNDI name of the EJBHome object. It is only needed if the entity or session bean exposes a remote view.
For JMS message-driven beans, this is the JNDI name of the JMS resource from which the message-driven bean consumes JMS messages. This information is alternatively specified within the activation-config subelement of the mdb-resource-adapter element. For more information about JMS resources, see Chapter 18, Using the Java Message Service, in Sun GlassFish Enterprise Server 2.1 Developer’s Guide.
