java.net.SocketException: Connection reset by peer: socket write error

victor281004387 2009-08-13 09:08:00
我用以下代码实现文件下载：



<%@ page language="java" pageEncoding="GB18030"%>

<jsp:directive.page import="java.net.URLEncoder"/>

<%

	String path = request.getContextPath();

	String basePath = request.getScheme() + "://"

	+ request.getServerName() + ":" + request.getServerPort()

	+ path + "/";

    

    //

    

    request.setCharacterEncoding("GB18030");

    String srcURL = String.valueOf(request.getAttribute("srcURL"));//资源路径

%>

<html>

    <head>

      <base href="<%=basePath%>">

    </head>

  

    <body>

      <%

      	response.setContentType("application/x-download");

      	String url = "/upload/"+srcURL;

      	String fileName = srcURL;

      	fileName = URLEncoder.encode(fileName, "UTF-8");

      	response.addHeader("Content-Disposition", "attachment;filename="

      			+ fileName);

      	RequestDispatcher rd = application.getRequestDispatcher(url);

      	rd.forward(request, response);

      	response.flushBuffer();

      	out.clear();

      	out = pageContext.pushBody();

      %>

    </body>

</html>


下载doc和txt格式的文件还可以，没有报错，可是下载ppt格式的文件他就报如下错误：

这些都是啥东西啊？既然是下载，把他们删除吧！
另外，加上一行
out.clearBuffer();
[/Quote]

加了out.clearBuffer();也不行哦，还有，我忘了说，我下载ppt的时候是按了“取消”才会报错的，正常下载的话是不会报错的
