Getting attachments and emails need serious help!!

Question

I am not sure if I am doing this right, but I am trying to receive emails from gmail, and I am having some serious problems. For some reason I get four emails and then I get a null exception. I have been through my code a dozen times and I cannot find the problem. Here is my code:     try{
                    Properties props = new Properties();
                    props.setProperty("mail.pop3.socketFactory.class", SSL_FACTORY);
                    props.setProperty("mail.pop3.port", "995");
                    props.setProperty("mail.pop3.socketFactory.port", "995");
                    Session session = Session.getInstance(props, null);
                    Store store = session.getStore("pop3");
                    store.connect("pop.gmail.com", "jwheat3300", "carrie11");
                    Folder folder = store.getFolder("INBOX");
                    folder.open(Folder.READ_ONLY);
                    int n=folder.getMessageCount();
                    attach = new String[n];
                    String select = "false";
                    String body = "";
                    for(int i=1; i<=n; i++)
                         Message message = folder.getMessage(i);
                         date2 = "3/2/2006";
                         from = message.getFrom()[0];
                         subject = message.getSubject();
                         attach="false";
                         Multipart multipart = (Multipart)message.getContent();
                         int j = multipart.getCount();
                         for(int l=0; l<j; l++)
                              Part part = multipart.getBodyPart(l);
                              disposition = part.getDisposition();
                              System.out.println(disposition);
                              if((disposition !=null) && ((disposition.equalsIgnoreCase(Part.ATTACHMENT) || disposition.equalsIgnoreCase(Part.INLINE))))
                                   MimeBodyPart mbp = (MimeBodyPart)part;
                                   if(mbp.isMimeType("text/plain"))
                                        body = (String)mbp.getContent();
                                        if(body==null)
                                             body="";
                                        bodies.add(new Body(body));
                                   if(mbp.isMimeType("text/html"))
                                        body = "This is an html email. Unable to display HELP";
                                        bodies.add(new Body(body));
                                   if(mbp.isMimeType("application/x-shockwave-flash"))
                                        attach[i] = "true";
                                   System.out.println(part.getContentType());
                              if(disposition == null)
                                   MimeBodyPart mbp = (MimeBodyPart)part;
                                   if(mbp.isMimeType("text/plain"))
                                        body = (String)mbp.getContent();
                                        if(body==null)
                                             body="";
                                        bodies.add(new Body(body));
                                        attach[i] = "false";
                                   if(mbp.isMimeType("text/html"))
                                        body = "This is an html email. Unable to display HELP";
                                        bodies.add(new Body(body));
                                        attach[i] = "false";     
                         inmails.add(new Inmail(select, from, subject, date2, attach[i]));
                         table.revalidate();
                    folder.close(false);
                    store.close();
               }catch(Exception t)
                         System.err.println("Exception900: " +t.getMessage());
I get the body fine, and what I am trying to do is when I get all of my information is to put this into the inmails vector and then update my table. That works but I am only gettting four of thirty emails. Also when it comes to attachments do I need to set up a mime type for every possible attachment that will come? I need some serious help!

Answer 1

I guess I am seriously confused then....I tried doing the tutorial from jguru on sun's site and this was how the code was set up. At least I think it is....I pretty much have no idea what I am doing. I mean the code as it stands will get the emails, and by the way this is for an application not for a server or anything. So should I check for it to be just plain text first and then find out if there is a multipart. There is not really any good tutorials that explain what it is I am trying to accomplish. Please help!
