JSP页面部分：
<%@ page contentType="text/html;charset=GB2312" %>
<%@ page import="tom.jiafei.UpFile" %>
<jsp:useBean id="upFile" class="tom.jiafei.UpFile" scope="session" />
<HTML><BODY> <P>选择要上传的文件：<BR>
<FORM action="" method="post" ENCTYPE="multipart/form-data">
<INPUT type=FILE name="boy" size="45">
<BR> <INPUT type="submit" name ="g" value="提交">
</FORM>
<% upFile.setRequest(request);
upFile.setSession(session);

<P>如果上传的是图像文件，可单击超链接查看图像：
<BR><A href="show.jsp"> 查看图像</A>

问下楼主是用的struts框架吗？
如果是的话首先要修改struts.xml文件
我给出的struts.xml配置文件代码，是以前做的上传视频文件的配置文件，你可以根据自己的需要进行修改
