In essence, it is a component veneer on top of a message queue. Microsoft calls this technology queued components and Sun calls it message-driven beans. The goal in both cases is to allow the use of a message queue to look as much as possible like an invocation of a method on a native component.

Remember from the discussion of homogeneous synchronous drawbridges that component technologies use surrogates in both ...
