Nops. I often pull very life components, like DB connections or SQL queries (we like to put SQL query templates in XML). But I also get strings and static lists of records. > In A4CM the string is required to indicate a ROle/interface while in > A4Context the key is an object.

I thought so at first but I find it very practical to do things like this: IConverter cvt = ctx.get(IConverter.class); This gets the type conversion "service" from my context. See? I use the context as a ServiceManager! =;o) I still found no problems with this approach. > A4CM = Service directory + specified key format > A4Context = Data directory + unspecified object format Well, at least we agree that a Context is a data directory... although it can be a Directory service too. =:o) > -- > Cheers, > > Pete > > ------------------------- > All things considered, > insanity may be the only > reasonable alternative. > ------------------------- Just my thoughts the other day messing up with my framework...
