Re: Let's just tell Sun to rewrite the JavaMail API. Was: What about IMAP support?

Bill!

And after I just bad mouthed you! So first I offer my heartfelt apology.
:-)

Also sorry for cross posting, I suggest we keep this discussion in one
place, James-dev is quite quiet.

Yep this is true, there's an API and a Reference Implementation.
And it does allow developers to add new protocols and MIME types.

I certainly wouldn't expect you to, but I hope I can convince you that
there's a middle ground where we can all benefit.

I don't believe that it is necessary to split the API per se, but consider
it this way..

A mail-client API and a mail-server API would be specialisations of a
generic mail API.
The generic API would be composed mainly of interfaces, and implementation
would be done by the specialisations.

This is reflects the fundamental principles of OOD.

What I'd like to see would be for more interfaces and fewer implementations
in the API itself, so that it could be left to
the developers of server software to replace Sun's implementation of an
interface with another implementation who's behaviour is better suited to
the specialisation.

MimeMessage is a case where I think we've missed the boat. It is probably
too entrenched in peoples use of javaMail for it's inheritance to be
meddled with but as a for-instance...

MimeMessage should be an interface.
AbstractMimeMessage should provide the basic functionality of MM, in terms
of the content type handlers and things.
ClientMimeMessage would implement MimeMessage but exhibit behaviour
appropriate in a client application (like the message-ID /saveChanges()
feature)
ServerMimeMessage would behave in a way specialised towards the
requirements of server software.

I'd like to look at the artificial distinction between Store and Transport,
and folders and the Session too to see if some meddling with inheritance
would at least give us the hooks on which we could hang server specialised
classes so that they would also be JavaMail implementations, I knw we can
achieve this at the moment, but not without going to some bizarre lengths
and to some extent loosing sight of the point of the exercise.

Re: Problems with outgoing email

[Richard O. Hammer]

Two tools which I find useful for troubleshooting such difficulties are:
1. telnet to port 25 of the server in question (one of the Yahoo 
servers which DNS is finding for you) and talk SMTP to it.  That is, 
type in SMTP commands and observe the responses.  You can send test 
messages to yourself in this low-level way.  For an example of a SMTP 
exchange, see RFC 2821, Appendix D.

2. Ethereal to capture the packets of a given exchange.  It is 
possible that some error message is being generated, in the exchange 
between javax.mail.Transport and the yahoo mail server, which is not 
being reported up to you.  By scrutinizing the SMTP exchange, which 
you can capture with Ethereal, you might find an error message.

Taking the plunge - Eclipse + Ant = James

[James Bucanek]

Greetings,

I'm about the take the plunge and see if I build James from source, then see if I'm 
programmer enough to contribute.  ;)

I'm taking this opportunity to learn/evaluate Eclipse at the same time.  Is anyone 
else here using Eclipse?  If so, is there anything I need to know about building James 
in Eclipse or accessing James' CVS repository via Eclipse?  (Ant scripts would be 
nice!)

If no one is using Eclipse, or has some reason why I shouldn't be using it, I'd like 
to know that too.

Thanks,

James

Hey James,
I'm not an active committer to this project, but I would highly
recommend Eclipse.  It really simplifies coding, and browsing through
code (well it simplifies a lot of other things too, but thats probably
all you are concerned with).  Let me help you in advance though, don't
get discouraged.  Eclipse is very logical in its usage, but it is a
little hard to discover these features.  But if you stick with it, you
will like it, I guarantee it.  Also, read up on it, while you are using
it, and remember right clicking is your friend.  It helps.
Edward

I have always used Eclipse to develop James code and am very happy with it.

1) Be sure to check out James as a Java Project (oddly enough), this is not
the default project type
2) Set the Project Properties to use a seperate directory such as
/dev/jamesHead
3) Once everything has been loaded, from the Java Perspective select your
new Project's Properties Select use source folders contained in the project,
add the existing folder 'src/java' and allow the ouput folder to be 'bin'.
4) To resolve compile errors you will need to ensure all the relevant
libraries are specified in the Library page which sets the classpath and
that JDK1.3.1 is used. To help you on your way I have attached the contents
of my .classpath file as a guide. I would suggest you use the GUI to enter
them rather than mess with the file!

> (Ant scripts
> would be nice!)

James has its own Ant script, build.xml. Personally, I always use this
outside of Eclipse as I want to be sure that the build as distributed will
work.

Also, I execute James outside of Eclipse using Eclipse's remote debugger to
attach to the remote JVM which in this case needs to be JDK 1.4.x.

I hope this helps,

-- Steve

Would you please do a writeup on using Eclipse with James, and post it to

No problem. In fact it would be useful to know where you had issues so that
we could highlight them in the a future Wiki entry.

Be sure to post to the James Developers List so others can add their
insights.
