高分求javamail收邮件servlet，写好发邮件的，却不会收，急呀

我找了好多都不行，大把imap的，vampirelord帮找找吧

不太明白你的意思,这是我一年前写的.    public void checkNewMail() {
        try {
            Properties props = System.getProperties();
            Session session = Session.getDefaultInstance(props, null);
            session.setDebug(debugFlg);            Store store = session.getStore("pop3");
            store.connect(mailHost, port, userName, password);            Folder folder = store.getDefaultFolder();
            if (folder == null)
                throw new NullPointerException("no default folder");
            folder = folder.getFolder("INBOX");
            if (folder == null)
                throw new NullPointerException("cann't open the folder: " + folder);
            folder.open(Folder.READ_WRITE);            vAllMail.removeAllElements();
            int totalMessages = folder.getMessageCount();
            if (totalMessages != 0) {
                // 新mail收到
                Message[] allMail = folder.getMessages();                if (allMail != null && allMail.length > 0) {
                    for (int i = 0; i < aAllMail.length; i++) {
                        //你的处理
                    }

其实我的意思是想得到一个完全的收邮件SERVLET。因为我一下写不来，请给我一个完整的程序好吗，我也想学一下了，vampirelord帮我了，谢谢！

skyyoung(路人甲)　你这个我有看过，也是你以前贴的，但我编译了却不知如何运行，如我的
邮件服务器地址是：192.168.0.1，用户为：[email protected] 密码：111111，要如何运行你那个程序，对了协议是pop3

调试易

高分求javamail收邮件servlet，写好发邮件的，却不会收，急呀
