Which Component Manager to use?

[Mark Woon <mo...@SMI.Stanford.EDU>]

Hi all...

I'm starting some new work and plan on using Avalon, but I haven't been 
keeping up with all the changes that have been taking place recently. 
 Is there any consensus as to which Component Manger I should be using 
if I'm starting from scratch?  I used to use the ECM, but since that's 
falling into disfavor, what's its replacement, if any?

How stable is Fortress?  Will Avalon 5.0 pretty much deprecate 
everything that's available now?

Thanks,
-Mark

Merlin isn't a component manager - its a tool/component you can use to 
compose and execute components.

It seems as if Fortress is the next-rev of the ECM. There is also Merlin, but 
I haven't looked at it yet.

What's your definition of stable :)

If you mean working without crashing, then yes. It is stable. (We use it in 
production over here). It is not stable from a modifications-will-happen 
standpoint. You have to be prepared to massage your code as needed when 
tracking the CVS version.

Yes - org.apache.avalon.framework.service.ServiceManager
It identical to ComponentManager with the exception that it is independent
of the Component marker interface.

Still cooking if I understand correctly.

Absolutly not - there is a lot of noice covering stuff that has been 
discussed lots of times before - I am confident on predicting that 
Avalon 5 will look very much like Avalon today - with perhaps a few 
carefully thought-out optimizations (and I really mean numbers of 
changescan be counted on the fingers of one hand - e.g. deprication of 
remove() on CM/SM would be one such change).

Cheers, Steve.
