I disagree. With serialization, it's impossible to change without
a tool or something. It's not like you can just "cat" in a block of
serialized data to "config.ser". With XML, you could just add or remove a
block of data in the (I'm speculating) "config.xml" file, right? (I'm
assuming the configuration information is stored in roughly the same form
as a deployment plan, which is to say, one file per configuration with
chunks defining each active GBean in the configuration.)
If push comes to shove, I like WebLogic's config.xml, which has
terse configuration for the entire server in a hierarchical XML format
(not like a properties file with a list of ports). If we're going to use
external "local" files, maybe they should look like that. I guess Tomcat
has a similar (if more verbose) configuration strategy for server.xml.
The problem is, any format like that would be super-tied to a J2EE
configuration, so it might be better for a separate project that
distributes a separately-certified J2EE-specific configuration of
Geronimo, and not very appropriate for a generic Geronimo "this server
might be assembled to do anything" build. Oh, dear, I think the
abstraction police are going to come and black out this whole paragraph.
Never mind. :)
