See www.iona.com/hyplan/vinoski/col9.pdf for information on the COS Event Service. See also: http://www.cs.wustl.edu/~schmidt/events_tutorial.html The COS Event Service interfaces are very simple and very general. In many ways, I wish that JMS had been modeled after them. There is nothing that is inherently distributed about the model. One of the first implementations of the specification was a tiny C++ version I did for embedded systems. And the COS Event Service does a very nice job of integrating both pull and push models of interaction. > I sumarize the OSGi Event Admin in the three slides available on > http://www-adele.imag.fr/~donsez/cours/osgi.pdf#page=100 Désolé, mais moi ne parlez pas français. Happily those three slides were in English. :-) I don't believe that we need Yet Another event model. Has the OSGi considered either a COS Event Service model or, since this is topic based, in-process JMS, such as Dave Walend's SomniFugi (https://somnifugijms.dev.java.net/)? --- Noel
