Hi,
I am new to the Apache efforts in COP and noticed, that there is a major
reorganisation going on. For newbies like me, this is a little
confusing.
As far as i can see, Avalon will now be hosted and maintained by the
Excalibur project, whereas Merlin goes Metro on DPML.net. Unfortunately,
this information is only available in mailing lists and is not reflected
on the project websites (yet?).
That is corrent.
My question here is: What is the difference/are the different goals ofThe major reason that Merlin/Metro has moved out of Avalon land is due to
Fortress and Merlin? Can someone please drop a short notice about that
question?
differences in the way the Merlin/Metro team wants to run the project and how
an Apache Software Foundation project should be run.
Merlin's design focus was more on macro (or large scale) servers, and was a direct competitor to what used to be Avalon Pheonix. Fortress' design focus was more on micro (or embedded within your application) container, and was a replacement for the ECM (ExcaliburComponentManager).
The design focus difference led to very different goals and implementation.
Fortress is designed to be easier to configure and put things together (it is
fairly forgiving).
Does fortress support hot deploy of components?Not at this moment. The framework is all there to perform this type of action,
but so far, none of the developers have come accross a situation where that
was truly necessary. We could get the same effect by shutting down one instance
of Fortress and starting it up immediately with the new configuration. Since this
does mesh up with what works on Servlet boundaries and most GUI applications,
it was good enough.
If you want to build something of that nature, we can definitely give you some
pointers.
thanks,
Bernhard
NP. I hope this helps.
