Into which category of middleware does GlassFish Message Queue software fit?
By most definitions, GlassFish Message Queue software cleanly falls into the Message-Oriented middleware category, also referred to as MOM. MOM is a relatively low level of abstraction within the middleware ranks, often running underneath complementary layers such as database and application adapters, event processing, and business process automation. By design, GlassFish Message Queue software attempts to focus on satisfying the primary characteristics of the MOM space, those being the actual message transfer functions, rather than adding functionality that overlaps with other layers of middleware. These MOM characteristics include functions such as message routing, persistence, guaranteed delivery, and transaction support.
