initialize() in James.java:
imapSystem = new SimpleSystem();
imapSystem.configure(conf.getChild("imapHost"));
imapSystem.contextualize(context);
imapSystem.compose(compMgr);
if (imapSystem instanceof Initializable) {
((Initializable)imapSystem).initialize();
}
compMgr.put("org.apache.james.imapserver.IMAPSystem",
(Component)imapSystem);
getLogger().info("Using SimpleSystem.");
imapHost = (Host)
Class.forName(imapHostClass).newInstance();
//imapHost = new JamesHost();
imapHost.configure(conf.getChild("imapHost"));
imapHost.contextualize(context);
imapHost.compose(compMgr);
if (imapHost instanceof Initializable) {
((Initializable)imapHost).initialize();
}
compMgr.put("org.apache.james.imapserver.Host",
(Component)imapHost);
getLogger().info("Using: " + imapHostClass);
As I understand it, the snippet code above sets up the IMAP server and
it's storage. So I think, it would be possible to select which service to
be run during James start-up; to prevent a service to be started, just
bypass its initialize() (and compose() if any), in James.java. And the
flags to init can be defined in the config.xml;
I'm not so clear (yet) how Phoenix working though; I defined my Block in
James' assembly.xml, my Block got loaded (meaning: its initialize() got
invoked) during Phoenix start-up. Could it be some differences between
blocks and components in Avalon parlance? ie: blocks got automatically
initialized and composed, but components' initialize() and compose()
should be invoked by some other entities.
Well, I don't know... quickly looking up the POP3Server.java, it's not a
block, but an AbstractService....
