try this:
 Properties props = new Properties();
 Session session = Session.getDefaultInstance(props,null);
 store = session.getStore("imap");

 store.connect("mail","user","pwd");
 folder = store.getFolder("INBOX");
 folder.open(Folder.READ_ONLY);
 Message message[] = folder.getMessages();
 for(int i =0, n =message.length; i<n; i++){
    if (!message[i].getFlags().contains(Flags.Flag.SEEN)) {
        System.out.println(i + ": " + message[i].getFrom()[0] + "\t" + message[i].getSubject());
    }
  }
 folder.close(false);
 store.close();

hi,

I accept that above code will work perfectly. But it will loop thru' all messages in the folder. Instead i like to fetch only the messages which has a particular flag(SEEN or RECENT etc).

In sense like to execute the imap search commands (RFC 2060) using the java mail API and fetch the results.

In java mail API, IMAPProtocol class contains the method search but it does not provides this functionality of fetching only message numbers.

Regards,
uma

ok - then try this:

 Properties props = new Properties();
 Session session = Session.getDefaultInstance(props,null);
 store = session.getStore("imap");

 store.connect("host","user","password");
 folder = store.getFolder("INBOX");
 folder.open(Folder.READ_ONLY);
 Flags flags = new Flags(Flags.Flag.SEEN);
 javax.mail.search.FlagTerm term = new javax.mail.search.FlagTerm(flags, false);
 Message message[] = folder.search(term);
 for(int i =0, n =message.length; i<n; i++){
    System.out.println(i + ": " + message[i].getFrom()[0] + "\t" + message[i].getSubject());
  }
 folder.close(false);
 store.close();

this is exactly what you want:
Flags flags = new Flags(Flags.Flag.SEEN);
javax.mail.search.FlagTerm term = new javax.mail.search.FlagTerm(flags, false);
Message message[] = folder.search(term);

if you use:
javax.mail.search.FlagTerm term = new javax.mail.search.FlagTerm(flags, true);

this will fetch the SEEN mails
