RE: James <-> JavaMail notification
Robert,
You could write a notification mailet. The nature of the notification
mechanism is up to you.

No, I hadn't looked at the code. The 20-30 minutes that I've had so far to
research the matter didn't permit any in-depth analysis... therefore I asked
the list. Thank you for answering. How does one best achieve this type of
notification using JAMES? I haven't looked at the Mailet API yet, is that
where I should start? Is there any way to have JAMES communicate with my
JavaMail application when a new message arrives?

Haven't you looked at the code? James doesn't currently use JavaMail to
store messages. How are you expecting the folder listener to work?

Hi James Users,
I'm trying to write a JavaMail application that notifies me when there is
new mail in my James inbox. My approach has been to register a
MailCountListener to the folder in a thread that keeps the folder connection
open:
folder.addMessageCountListener(new javax.mail.event.MessageCountListener() {
public void messagesAdded(javax.mail.event.MessageCountEvent e) {
System.out.println("You've got mail!");
}
public void messagesRemoved(javax.mail.event.MessageCountEvent e) {
//do nothing
}
});
But, alas, it's not working. I know this isn't a JavaMail list, but I was
wondering if anybody has any advice, code examples, related experience to
help guide me.
Thanks,
Robert Douglass

Here's a quick hack I did to check your email every 10 minutes. Just plug
your pop-server name, your userID and password.
You must download JavaMail and include in CLASSPATH
CheckMyEMail.java
/*
* CheckMyEMail.java
*
* Created on July 10, 2002, 9:00 PM
* @author Ramon Gonzalez
*/
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
public class CheckMyEmail {
public static void main(String args[])
throws Exception {
String pop3Host = "pop-server.tampabay.rr.com"; //pop host name
String user = "userid"; //pop user Id
String password = "password"; //POP Password
int checkPeriod = 10; //checks inbox every x minutes
CheckMyEmail checkMyEmail = new CheckMyEmail();
while (true) { //loops every x minutes forever
checkMyEmail.process(pop3Host, user, password);
Thread.sleep(checkPeriod*1000*60); //sleep every x minutes
}
}
/** process() checks for new messages
*/
public void process(String pop3Host, String user, String password)
throws Exception {
String INBOX = "INBOX";
String POP_MAIL="pop3";
try {
// Get a Session object
Properties sysProperties = System.getProperties();
Session session = Session.getDefaultInstance(sysProperties,
null);
session.setDebug(false); //set to true for session debug
Store store = session.getStore(POP_MAIL);
store.connect(pop3Host, -1, user, password);
// Open the default folder
Folder folder = store.getDefaultFolder();
if (folder == null)
throw new NullPointerException("No default mail folder");
folder = folder.getFolder(INBOX);
if (folder == null)
throw new NullPointerException("Unable to get folder: " +
folder);
// Get message count
folder.open(Folder.READ_WRITE);
int totalMessages = folder.getMessageCount();
if (totalMessages == 0) {
//System.out.println(folder + " is empty"); //use to see if
empty
} else {
System.out.println("You have Mail! There are " +
totalMessages+ " messages in your " + folder + " folder.");
}
folder.close(false);
store.close();
return;
} catch (Exception e){
System.out.println("Exception while checking email count.");
}
}
}

Or you could write a mailet to send some sort of IM type notification, e.g.,
using Jabber or IRC on a private channel, over a socket, pager, etc. All
sorts of things one could do.

You can write a Mailet that will do a System.out.println in the JAMES
console whenever an email with your user account name comes in.
Or you can wirite a JavaMail application that will connect via POP, look at
your default folder, and count how many emails you have and notify you.

There was a bug in MimeMessageSource (InputStreams were not closed), which was fixed in May.
Try to use a newer version of James.

Too Many Open Files
Posted by Stephen <ja...@spamgourmet.com>.
Hello,
Running James 2.0a2 on Windows 2000, using the filesystem as the
repository. When there are lots of messages for a user (problem
is seen somewhere between roughly 1000-2000 messages), an error is
returned when the user tries to retrieve these messages via POP.
From the server logs, this error appears to have something to do with
"too many open files".
When I last saw this, I stopped James and moved (the newest) 1/2 of the
files from the user's inbox folder to a temporary folder. Restarted James,
and was able to download the oldest messages. I then stopped James,
restored the files from the temporary folder back to the inbox, and was now
able to download these newest messages.
Is this a known issue? Is there anything I can do to avoid the problem
(besides more frequent downloading of emails)? Will an upgrade to 2.0a3
help?
Stephen
