java中接收邮件的附件无法下载的问题？？？

[shanxmxj]

系统收发邮件用的webmail,框架是ofbiz,数据库是oracle,中间件tomcat

问题是这样的：在收邮件时，附件下载的时候，另存的对话框出不来。

下载附件的代码：

/**
   * 下载附件
   * @param request HttpServletRequest
   * @param response HttpServletResponse
   */

  public static void do_showpart(HttpServletRequest request,
                                 HttpServletResponse response) throws
      ServletException {
    String rootPath ="";
    long lStoreHandle = 0;
    HttpSession session = request.getSession();
    String strAttachId = request.getParameter("attachId");
    try {
      String strFolder = (String) request.getSession().getAttribute(
          "sit.mail.folder");
      if (strFolder == null)
        strFolder = "INBOX";
      GenericDelegator delegator = (GenericDelegator) request.getAttribute(
          "delegator");
      GenericValue attach = delegator.findByPrimaryKey("Attachment",
          UtilMisc.toMap("attachId", new Integer(strAttachId)));
      String strFilename = attach.getString("filename");
      String ApplicationSystem = (String) session.getAttribute(
          "sit.mail.ApplicationSystem"); //应用服务器
      if (ApplicationSystem != null &&
          "websphere".equals(ApplicationSystem.toLowerCase()))
        strFilename = new String(strFilename.getBytes(), "ISO-8859-1");        //tianbj update 2006-04-17
        //byte[] content = (byte[]) attach.get("content");
        //ByteArrayInputStream is = new ByteArrayInputStream(content);
      String cluster = UtilProperties.getPropertyFileValue(
        "/office.properties", "system.cluster");
    if ("false".equals(cluster.toLowerCase())){
       rootPath = UtilProperties.getPropertyFileValue(
          "/office.properties", "office.root.path");
    }else{
      rootPath=rootPath=UtilProperties.getPropertyFileValue(
          "/office.properties", "office.protect.mail.path");
    }
      String filePath = rootPath + "/accessoryDirectory/webmail/" +
          String.valueOf(strAttachId) + "/" + strFilename;

      FileInputStream fis = new FileInputStream(filePath);
      OutputStream cOutputStream;
      cOutputStream = response.getOutputStream();
      byte[] byteBuffer = new byte[256];
      int l26;
      response.setHeader("Content-disposition",
                         "attachment;filename=" + strFilename);
      response.setHeader("Filename", strFilename);
      while ( (l26 = fis.read(byteBuffer)) != -1) {
        cOutputStream.write(byteBuffer, 0, l26);
      }
      cOutputStream.flush();
      cOutputStream.close();
    }
    catch (Exception e) {
      Debug.log(e);
      throw new javax.servlet.ServletException(e.toString());
    }
  }

在本地测试时是没有问题的，本地用的是tomcat的中间件。
而部署到用户的环境上就出问题了。
用户那里服务器是win2003的系统，应用是部署到集群上的，中间件是websphere.

在程序中进行判断了，如果是websphere的话 对附件名称进行转码。
在mail.ini的配置文件中也配置了
[code=INIFile]<entry name="sit.mail.ApplicationSystem" value="websphere" />[/code]
附件存放的路径也没有问题。
请大家帮忙这个附件名称的编码我现在应该怎么转??谢谢了！

我是根据错误信息判断是附件名称的转码问题，但是转成GBK 或者GB2312也都不行。向高手请教!!在线等
