How to get all unread emails in JAVA from lotus notes domino server

Question

I am new to Notes JAVA API and developing a utility where I require to read all unread mails from a Lotus notes id.Now when i try to use lotus.domino.Database.getAllUnreadDocuments() it gives me the following exception

NotesException: Not implemented
at lotus.domino.cso.Base.notImplemented(Unknown Source)
at lotus.domino.cso.Document.markRead(Unknown Source)
at com.email.ReadEmailRemotely.readEmails(ReadEmailRemotely.java:428)
at com.email.ReadEmailRemotely.run(ReadEmailRemotely.java:96)
at java.lang.Thread.run(Unknown Source)

My application is a plain JAVA application in eclipse using NCSO.jar

My question is , do i need to extend lotus.domino.AgentBase ?

If yes then what all dependencies do i require as , JAVA app is not allowing to extend it. & if no then is there any other way to get all unread mails?

Answer 1

If the server supports IMAP or POP3, you can use JavaMail API, which is pretty easy and has a flag for unread messages.

    Properties props = System.getProperties();
    props.setProperty("mail.store.protocol", "imaps");

    try {
            Session session = Session.getDefaultInstance(props, null);
            Store store = session.getStore("imaps");
            store.connect("myserver.com", "user", "pass");

            Folder inbox = store.getFolder("Inbox");
            inbox.open(Folder.READ_ONLY);

            FlagTerm ft = new FlagTerm(new Flags(Flags.Flag.SEEN), false);
            Message messages[] = inbox.search(ft);
     }

Answer 2

An easy way (assuming you are can edit the NSF) is to create a hidden view which lists only the documents you want to get back.

Then access that view and iterate through it.

Answer 3

You will have to switch to using notes.jar instead of ncso.jar.

In order to use notes.jar and access the getAllUnreadDocuments method, you will need to install Notes and Domino 8 or above on the system where your code is running.

Answer 4

May require Secure Connection(SSL), Use the following properties to connect mail server supporting POP3 protocol:

        properties.put("mail.pop3.socketFactory.port", "POP3_PORT");
        properties.put("mail.pop3.host", "POP3_SERVER_HOST_NAME_OR_IP");
        properties.put("mail.pop3.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        properties.put("mail.pop3.socketFactory.fallback", "false");
