Java Mail API and Exchange 2003

[Hendrik van der Watt]

Hi

I am trying to retrieve email from an Exchange 2003 server using pop3 protocol. I can login with the domain user and open the mailbox, even retrieve how many message it contains, but when I try and retrieve the messages from the folder I get java.lang.NoClassDefFoundError: javax/activation/DataSource.

Message[] msgs = null;
      try {
        msgs = folder.getMessages();
        FetchProfile fp = new FetchProfile();
        fp.add(FetchProfile.Item.ENVELOPE);
        fp.add(FetchProfile.Item.FLAGS);
        fp.add("X-Mailer");
        folder.fetch(msgs, fp);
 

      }
 
      catch (NoClassDefFoundError e) {
        LOGGER.error(e.toString());
      }
      catch (Exception ex) {
        LOGGER.error(ex.toString());
      }  

If anyone else have encountered this problem and managed to resolve it please assist.

Thanks

Hendrik

Search for and incluse the activation.jar on your classpath.

The JavaRanch forum is for conversations relating to the JavaRanch site. This topic will be moved to the Other Java APIs forum.

I am trying to fetch mails from mailserver 2003 using JAVA swing can any one help to make me such programme?

There are many JavaMail tutorials available; at my job I have bookmarks to articles on Javaworld and jGuru. But keep in mind that the MAPI protocol is not easy to use since it is a Microsoft proprietary protocol. Your Exchange mailbox should support either IMAP or POP3. If it doesn't you should contact your system administrator.

No. We are NotACodeMill. You should DoYourOwnHomework. But you're in luck, I'm at my job now so I have my shortcuts. Here they are:
- JavaMail quick start @ Javaworld.com.
- Fundamentals of the JavaMail API @ jGuru

I already told you to use IMAP or POP3, didn't I?
