同时搜网(www.tongshisou.com)是一个很有创意的搜索网站,是目前最易用,最方便的整合搜索网站,本身不做搜索却把业界的搜索引擎聚合在自己网站中,包括百度,GOOGLE,YAHOO,中搜,爱问,搜狗,奇虎,腾讯搜搜,OPENV,TVIX,有网页 新闻 图片 音乐 视频 地图 工作 餐饮 的搜索，可谓很全哦,搜索起来确实方便,而且很易用,可以把结果同时在一个网页中以分割条形式分开,而且可以分割成2-4个窗口,大家可以一试哦www.tongshisou.com

StringBuffer msg = new StringBuffer();
        msg.append("中间可以加入所要发到邮箱的页面");
        msg.append("中间可以加入所要发到邮箱的页面");
        msg.append("中间可以加入所要发到邮箱的页面");
        msg.append("中间可以加入所要发到邮箱的页面");
        msg.append("中间可以加入所要发到邮箱的页面");try {
            EmailTool emt = new EmailTool();  //实例化下面发送邮件的功能bean
            emt.setTo(要发送到的邮箱);
            emt.setFrom("发送地址");
            emt.setSubject("发送的标题"）
            emt.setContent(msg.toString());  //内容格式转换
            emt.setSmtpHost("邮件服务器地址。自己申请");
            emt.setUser("服务器用户名");
            emt.setPassword("服务器密码");
            emt.startSend();
        } catch (Exception e) {}
//注  ：注意写法与页面一样，但是页面中的双引号一定要换成单引号
功能bean太长，不让发下个帖子发
