This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up with different versions on classes on the class path).

There is a newer version: 33.0.2.Final

/**
 * Address identifies cluster member. For example, whenever a unicast message is sent in a cluster
 * an Address of a cluster member message recipient needs to be specified. Similarly a cluster
 * member can use Address to check its own identity, request a state from a particular member and so
 * on. Addresses are mostly generated by the bottom-most (transport) layers (e.g. UDP, TCP,
 * LOOPBACK).
