Struts DownLoadAction 下载文件的中文名乱码

[xingliang_liu]

用DownLoadAction下载文件，
代码如下：
protected StreamInfo getStreamInfo(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception{

response.setHeader("Content-disposition", "attachment;filename ="+fileName);//fileName为文件名称
File file = new File(filePath);//filePath为原文件保存路径

jwJxssjhWlkjDao.closeSession();

// TODO Auto-generated method stub
return new FileStreamInfo(contentType,file);//contentType为文件类型
}

如果fileName为英文没有问题
但如果是中文就不行

fileName=new String(fileName.getBytes(),"ISO8859_1");
