struts2下载chm格式文件出现问题

action：（一种绝对路径，一种相对路径都试了）

public java.io.InputStream getInputStream() {
//  return ServletActionContext.getServletContext().getResourceAsStream(this.getInputPath());
  InputStream stream = null;
  try {
   stream = new java.io.FileInputStream(this.getInputPath());
  } catch (FileNotFoundException e) {
   e.printStackTrace();
  }
  return stream;
 }
 
 public String execute() throws Exception {
//  String filePath = ServletActionContext.getRequest().getContextPath();
  String fullPath = ServletActionContext.getServletContext().getRealPath("/help.chm");
  this.setInputPath(fullPath);
  setFilename("help.chm");
  log.debug("下载帮助.");
  return "successDown";
 }

 

 

xml配置文件：

<action name="downHelp" class="downHelpAction">
          <param name="inputPath">${inputPath}</param>
             <result name="successDown" type="stream">
                 <param name="inputName">inputStream</param>
                 <param name="contentDisposition">attachment;filename=${filename}</param>
             </result>
             <result name="fileError">error.jsp</result>
   </action>

 

 

问题：

在我本机一切正常，部署到linux服务器下下载chm文件直接打开里面页面都找不到，下载下来打开也一样。

别人访问我机器(winxp)下载也不行.

但是我自己下下来传给别人他们又能打开.

到底是怎么回事？

流是一种解决方案。但是要用struts2封装的下载框架为什么不行？？
public void downLoad(String filePath, String contentType) throws Exception {
File f = new File(filePath);
if (!f.exists()) {
res.sendError(404, "对不起，下载文件没有找到，无法下载!");
return;
}
BufferedInputStream br = new BufferedInputStream(new FileInputStream(f));
byte[] buf = new byte[1024];
int len = 0;
res.reset(); // 非常重要
res.setContentType(contentType + ";charset=utf-8");
res.setHeader("Content-Disposition", "attachment; filename="+ f.getName());
OutputStream out = res.getOutputStream();
while ((len = br.read(buf)) > 0)
         out.write(buf, 0, len);
br.close();
out.flush();
out.close();
}
