Extracting attachments from Lotus Notes Email with Java

In my project I am attempting to read lotus notes email in the Inbox. Right now I have two emails in my inbox, each email has an attachment, and I am trying to open each email and download the attachment from that email.

The issue I am having now is that my program is only reading the first email.

try
    {
        NotesThread.sinitThread();

        Session session = NotesFactory.createSession();
        Database database = session.getDatabase("servername", "mailbox link");
        View view = database.getView("$Inbox");
        Document document = view.getFirstDocument();

        while(document != null)
        {

            RichTextItem Body = (RichTextItem)document.getFirstItem("Body");
            Vector vector = Body.getEmbeddedObjects();
            Enumeration iterator = vector.elements();

            while (iterator.hasMoreElements())
            {
              EmbeddedObject eo = (EmbeddedObject)iterator.nextElement();
              if(eo.getType()==EmbeddedObject.EMBED_ATTACHMENT)
                {
                    attachment = eo.getName();
                    eo.extractFile("destination" + eo.getName());
                    eo.remove();
                }

            }//end of inner while


            logger.info("Received email and downloaded attachment");
            document = view.getNextDocument(document);

        } //end of outer while



    } 
    catch(NotesException nex)
    {
       logger.severe("Exception in INotes connection");
    }
    finally
    {
        NotesThread.stermThread();

    }

I thought the line -- document = view.getNextDocument(document)

would open the next email in the Inbox. But I am only getting the first email as the result.

Appreciate any pointers.

You can use view.getFirstDocument, get the first mail, and use the view.getNextDocument (Document document) to read the next message. Or use view.getNthDocument (int index) to read mail.

This code works for me. Though written for Notes 8 it also works on Notes 9.

try
    {
        Session s = NotesFactory.createSession((String)null, (String)null, NotesAuth.getPassword());
        Database db = s.getDatabase(null, "C:\\notes\\data\\mymail.nsf");

        DocumentCollection collection = db.getAllDocuments();

        Document doc = collection.getFirstDocument();
        System.out.println("DB Doc Count = " + collection.getCount());

        while (doc != null)
        {
            String type = doc.getItemValueString("Form");

            if (type==null) type = "*none*";

            CountRec cr = map.get(type);

            int docAttCount = 0;
            int docAttSize = 0;

            Object body = doc.getFirstItem("Body");

            if (body!=null && body instanceof RichTextItem)
            {
                @SuppressWarnings("rawtypes")
                Vector att = ((RichTextItem)body).getEmbeddedObjects();

                if (att.size()>0)
                {
                    for (int i = 0; i < att.size(); i++)
                    {
                        EmbeddedObject a = (EmbeddedObject)att.get(i);
                        docAttSize += a.getFileSize();
                    }

                    docAttCount += att.size();
                }
            }

            if (cr==null)
            {
                cr = new CountRec(type);
                map.put(type, cr);
            }

            ++cr.count;
            cr.totalSize += doc.getSize();
            cr.docAttachCount += docAttCount;
            cr.docAttachSize += docAttSize;

            Document newDoc = collection.getNextDocument(doc);
            doc.recycle();      // need to do this to prevent "out of backend memory" error
            doc = newDoc;
        }

It reads everything in the mail DB but you can select on Form = 'Memo' or 'Reply' to deal with the only the actual email documents.
