I have a link /1/, when I put it into brower address bar (remmeber to remove single quotation at the beginning and at the end). It is a image/png picture.

我有一个链接/1/，当我把它放入brower地址栏(remmeber在开始和结束时删除单引号)。这是一张图像/png图像。

Now I want to show this picture by jetty comet feature by pushing to client. I have a js, part of codes is in /2/, then in the client page/browser(firefox and chrome), I could not see picture, but raw data. In web.xml, I already put mime type /3/. Could any expert drop me some hints how to show picture when sending data from server to client?

现在我想用jetty comet的特性来展示这张照片。我有一个js，部分代码在/2/，然后在客户端页面/浏览器(firefox和chrome)，我看不到图片，但是原始数据。在网络上。xml，我已经放了mime类型/3/。是否有专家可以给我一些提示，在从服务器发送数据到客户端时如何显示图片?

/1/Please remove single quotation at the begining and at the end of block

/1/请在开始和结束时删除单引号。
