firefox 和 ie 的文件类型区别
Firefox：
image/jpeg, image/bmp, image/gif, image/png
ie 6：
image/pjpeg ,image/bmp, image/gif, image/x-png
ie 7：
image/pjpeg, image/bmp, image/gif, image/x-png
ie 8：
image/pjpeg, image/bmp, image/gif, image/x-png
Ie 9：
image/jpeg, image/bmp, image/gif, image/png
所以在struts.xml配置文件中需要
<param name="allowedTypes">
image/bmp,image/png,image/gif,image/jpeg,image/jpg,
image/pjpeg ,image/bmp, image/gif, image/x-png,
</param>
