Naah - event driven approaches are an othogonal concept. While neat I doubt they will ever gain real popularity because of the difficulty of implementing them properly. The only real gain is for separating app layers and operating under sustained loads. I think it will gain a little on backend but threaded high level layered apis (ie Servlet API) are where it's at for 99% of programmers. Then again - I may be biased as I spent two years of my life debugging one of these messes ... errr systems ;) However that has nothing to do what I am talking about. What I am talking about is the implementation strategy for adding arbitary aspects to services. Need persistence? No problem. Need replication, clustering and synchronization? Doable. Need Instrumentation? Easy. Need to load Avalon "services" that wrap a web service - piece of piss. Need to persist the changes from this web service. Not a problem. -- Cheers, Peter Donald ---------------------------------------------- Money is how people with no talent keep score. ---------------------------------------------- -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
