本文介绍了一个关于使用JFreeChart生成的图片无法在Internet Explorer中正常显示的问题。该问题出现在Windows 2003环境下，Tomcat 5.5服务器，并且仅限于IE浏览器。文中提供了解决方案：通过回退到JFreeChart的老版本如1.0.2或5。此问题在Firefox浏览器中不存在，同时图片也能正确保存到硬盘。

Cannot show the image generated by jfreechart within IE


response.setContentType("image/jpeg");
os = response.getOutputStream();
os.write(((ByteArrayOutputStream) cos).toByteArray());
//os2 = new FileOutputStream("D:/ss.jpg");
//os2.write(((ByteArrayOutputStream) cos).toByteArray());
response.flushBuffer();

Environment: windows2003, Tomcat5.5, jfreechart1.0.9/11.

Symptom: The image(jpg) generated by jfreechart cannot be shown in IE(Red X), but correctly shown in firefox and also correctly saved in harddisk.

Solution: Use a older version jfreechart such as 1.0.2 or 5.

Sum-up: Take the open source as the code writen by myself, there are many bugs hidden in them too.
