网页调用处代码

upFileBean.setResponse(response);
new Thread(upFileBean).start();

重启tomcat后第一次不管传什么文件都能正确上传
但接下来传就出现如题的问题
请高手指点一二。谢谢

偶自己解决了
分还是自己拿算了

[lixiaoxue85]

你分能给自己?

[suwei372]

我想知道你是怎么解决的阿

[suwei372]

错误原因在哪

[悟影]

还在这里问啊，我QQ258322672，上线了加我，我传给你那点上传的源码。。

[悟影]

好像是直接调用线程run()方法就不会出现那个读起时的问题(不是调用线程start方法)，
后来改的代码如下
<%@ page contentType="text/html; charset=gb2312" language="java" errorPage=""%>
<%@page import="arch.userlogin.*" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB2312">
<title>文件上传</title>
</head>
<body>
<%//session.removeAttribute("upFileBean"); %>
<jsp:useBean id="upFileBean" scope="session" class="arch.upload.UpFileThread"/>
<%
User user=(User)session.getAttribute("user");
if(user!=null&&user.getSorts()!='0'){
//arch.upload.UpFileThread upFileBean=new arch.upload.UpFileThread(request,response);
upFileBean.setRequest(request);
upFileBean.setResponse(response);
new Thread(upFileBean).run();
//upFileBean.run();
%>
<%response.sendRedirect("upstatus.jsp"); %>
<%}else{ %>
<script type="text/javascript">
<!--
alert("您无权访问");
history.back();
//-->
</script>
<%} %>
</body>
</html>

和start()方法真的有关系吗？
