Selecting services
Hi,
I'd like to turn off nntp and imap servers; how am I supposed to do it?
Removing the elements in config.xml seems to prevent James from starting.
BTW, I'm going to use James 1.3-dev (the one in the CVS).
TIA,
Oki

Yes - blocks get automatically run by Phoenix. Before we split James
into multiple blocks it was straightforward to specify what services
were run. I haven't had time to play with current set-up for that.
The IMAP code generally needs some attention, so I wouldn't rely on it
for examples.
And, yes, components within blocks should be set up by their block, I
think.

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....

I think we should ask the avalon guys about turn on/off blocks... Avalon manage
all the services and I think it should enough to specify in the manifest.mf if
it is a service (block) or not. I think it is maybe a bug in the current version
of avalon we use!

Thanks a lot; I'll try it out.

Whoa, so many things to do just to turn on/off services; it's time to
think about a "james-meta.xml" which (approx.) contains:
<meta-james>
<smtp service="yes"/>
<pop service="yes"/>
<nntp service="yes"/>
<imap service="yes"/>
</meta-james>
And then just put "no" if you don't want some services to be started.

Interesting... Is it a bug or a feature?
I see... symbolic links.

Hi Oki
Try this way...

Ok, I see... I tried it out... and got an java.lang.OutOfMemoryError but found
nothing in the log files!
I played a little bit around and here my solution:
for the NNTP Service
--------------------
In the manifest.mf:
Name: org/apache/james/nntpserver/NNTPServer.class
Avalon-Block: false
Name: org/apache/james/nntpserver/repository/NNTPRepositoryImpl.class
Avalon-Block: false
Comment out or remove the 2 blocks in the assembly.xml and config.xml!
This should work!
for the IMAP service... I'm not sure if this works also... try it out... take
care about dependencies to the block James!

If I understand avalon right... the path in the location are always realtive to
the application home path! Use symbolic links for the log directory in your
james app home.
I hope this help!

I tried that, but then James couldn't be started.
Should I remove some of the elements in server.xml?
BTW, I'd like to change the directory of the log files. I tried to change
the "location" attributes in james-server.xml to /var/log/james/<log
name>. But then, the log files didn't get placed in /var/log/james; they
were still under the James intstallation directory.
