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?
