2、记住要引入iframe.js文件

下面是iframe.js的具体内容

var browserVersion = window.navigator.userAgent.toUpperCase();

var isOpera = browserVersion.indexOf("OPERA") > -1 ? true : false;

var isFireFox = browserVersion.indexOf("FIREFOX") > -1 ? true : false;

var isChrome = browserVersion.indexOf("CHROME") > -1 ? true : false;

var isSafari = browserVersion.indexOf("SAFARI") > -1 ? true : false;

var isIE = (!!window.ActiveXObject |" alt="自动适应iframe右边的高度" title="自动适应iframe右边的高度" width="200" height="150">

" scrolling="no">

" scrolling="no">

用于展示邮件的信息

DisplayHead.java

package mail;

import java.io.IOException;

import java.io.PrintWriter;

import java.text.DateFormat;

import javax.mail.BodyPart;

import javax.mail.Folder;

import javax.mail.Message;

import javax.mail.Multipart;

import javax.mail.internet.MimeUtility;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpSession;

@SuppressWarnings("serial")

public class DisplayHead extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

response.setContentType("text/html;charset=gb2312");

PrintWriter out = response.getWriter();

HttpSession session = request.getSession();

int msgnum = Integer.parseInt(request.getParameter("msgnum"));

Folder folder = (Folder) session.getAttribute("folder");

try {

Message msg = folder.getMessage(msgnum);

String from = msg.getFrom()[0].toString();

String subject = msg.getSubject();

String sendDate = DateFormat.getInstance().format(msg.getSentDate());

out.println("邮件主题：" + subject + "
");

out.println("发件人:" + from + "
");

out.println("发送日期：" + sendDate + "

");

System.out.println("contentType：" + msg.getContentType());

// 如果该邮件是组合型"multipart/*"则可能包含附件等

if (msg.isMimeType("multipart/*")) {

Multipart mp = (Multipart) msg.getContent();

for (int i = 0; i < mp.getCount(); i++) {

BodyPart bp = mp.getBodyPart(i);

// 如果该BodyPart对象包含附件，则应该解析出来

if (bp.getDisposition() != null) {

String filename = bp.getFileName();

System.out.println("filename：" + filename);

if (filename.startsWith("=?")) {

// 把文件名编码成符合RFC822规范

filename = MimeUtility.decodeText(filename);

}

// 生成打开附件的超链接

out.print("附件：");

out.print("

+ ">" + filename + "

+ ">" + filename + "

}

}

}

} catch (Exception e) {

e.printStackTrace();

}

}

}

用于显示邮件头内容

DisplayContent.java

package mail;

import java.io.IOException;

import javax.mail.BodyPart;

import javax.mail.Folder;

import javax.mail.Message;

import javax.mail.Multipart;

import javax.servlet.ServletException;

@SuppressWarnings("serial")

public class DisplayContent extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

ServletOutputStream sos = response.getOutputStream();

HttpSession session = request.getSession();

int msgnum = Integer.parseInt(request.getParameter("msgnum"));

Folder folder = (Folder) session.getAttribute("folder");

try {

Message msg = folder.getMessage(msgnum);

// 邮件类型不是mixed时，表示邮件中不包含附件，直接输出邮件内容

if (!msg.isMimeType("multipart/mixed")) {

response.setContentType("message/rfc822");

msg.writeTo(sos);

} else {

// 查找并输出邮件中的邮件正文

Multipart mp = (Multipart) msg.getContent();

int bodynum = mp.getCount();

for (int i = 0; i < bodynum; i++) {

BodyPart bp = mp.getBodyPart(i);

/*

* MIME消息头中不包含disposition字段， 并且MIME消息类型不为mixed时，

* 表示当前获得的MIME消息为邮件正文

*/

if (!bp.isMimeType("multipart/mixed") && bp.getDisposition() == null) {

response.setContentType("message/rfc822");

bp.writeTo(sos);

}

}

}

} catch (Exception e) {

e.printStackTrace();

}

}

}

用于显示邮件正文

HandleAttact.java

import javax.mail.Message;

import javax.mail.Multipart;
