  111.         return super.execute();  
  112.     }  
  113. }  

 struts.xml配置如下：

但是，我明明上传的文件格式是正确，还是出现：

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>
