James configuration
Two things...
1. I was under the impression that as Avalon/Phoenix handled instantiating
repositories, it would make sure duplicates of the same repository would not
be created.
For instance, if the conf file specifies file://var/mail/spool, and in
another part of the conf file there is also file://var/mail/spool, then the
two different parts of James would get the same object, even though they're
using different parts of the conf file. I think Charles recently modified
the conf of the spool repository to manaully control only one instance
getting created. Is this how James is supposed to be designed, or was this
a bug in Avalon/Phoenix?
2. If we can assume that repository URLs are unique, I'd like to make the
JDBC repository's URL look something like this....
db://<datasource>/<repository_name>. The "datasource" would need to be
configured in a separate and centralized place in one of the xml conf file,
and would include driver, jdbc URL, and optionally username, password, table
name, and field names.
Does this seem like a good approach to configure of the JDBC repository, and
can anyone give me pointers on where to stick the datasource configuration
and how to access it when it's initialized?
Thanks.

IMHO, it would be better to have JDBC.conf.xml (or, JDBC-conf.xml; hey,
I'm using debian here); having .ini files in Linux machines doesn't
sound right.

Sounds good to me, but is there any way I can leverage Phoenix to load this
conf file for me? Otherwise I see two options:
- use a properties type file, which is...
- easy to implement
- inconsistent with the other conf files
- less structured, so more difficult to define multiple datasources in the
same file
- use an XML file, which is...
- more code to write
- create XML parser dependencies that might create version problems with
Phoenix (if Phoenix changes parsers, this code has to change to)
Anyone know a good way?

I'm currently not fussed whether the jdbc config goes in the main config file
or there is just a pointer.

This should happen - specifically AvalonMailStore should do this (which we
should really remain DefaultMailStore - there's nothing Avalon specific here)

Yes, that should happen.

Really that was because if you have two definitions but you only want one
repository, there is a high likelyhood that you would not specify them
identically.

Its not an Avalon/Phoenix question.
Have you found a bug? ie identical repository definitions returning different
objects?

I think the MailStore section of the config.xml file is the place for this (or
at least a reference to an external file).

The basic config for a datasource should be like a USerJDBCRepository, I guess,
so I think similar config elemements and code should work.

What would you set true or false?

Isn't a cleaner aproach to set a true or false and handle all the connection
data in a single file, asccii or xml ?
