EM. Jini Event Mailbox Service Specification

The Jini Event Mailbox Service Specification defines a Jini service that can be employed by Jini technology-enabled clients and services to store event notifications on their behalf. When an entity registers with the event mailbox service, that service will collect events intended for the registered entity until the entity initiates delivery of the events. A service such as the event mailbox can be particularly useful to entities that desire more control over the delivery of the events sent to them. Some entities operating in a distributed system may find it undesirable or inefficient to be contacted solely for the purpose of having an event delivered; preferring to defer the delivery to a time that is more convenient, as determined by the entity itself.
