有一个上传文件的JSP程序，运行时可以选择上传的文件，但单击“上传按钮"后，则显示
HTTP Status 404 - /ch10b/servtlet/Upload。共有2个程序，1个是客户端上传给服务器的JSP程序selectFile.jsp,代码如下：
<%@ page contentType="text/html;charset=GBK" %>
<HTML>
<HEAD><TITLE>file upload</TITLE></HEAD>
<BODY>
<CENTER><H1><B>文件上传</B></H1></CENTER><BR>
<FORM name="selectfile" enctype="multipart/form-data" method="post" action="servtlet/Upload">
<P>文件名称：
<INPUT type="file" name="ulfile" size="20" maxlength="80">
</P><P>
<INPUT type="submit" value="上传"><INPUT type="reset" value="清除">
</P>
</FORM>
</BODY></HTML>
第2个程序为将文件上传的Servlet程序Upload.java,代码如下：
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Upload extends HttpServlet
{
// 响应POST请求
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException,IOException
{
response.setContentType("text/html;charset=GB2312"); //设置响应的MIME类型
PrintWriter out = response.getWriter(); //获得向客户发送数据的输出流
try{
InputStream source=request.getInputStream();
String Ph="F:/xiti/ch10/WebContent";
File f = new File(Ph,"text2.txt");
FileOutputStream target=new FileOutputStream(f);
byte buff[]=new byte[1024];
int temp;
while((temp=source.read(buff))!=-1)
{ target.write(buff,0,temp); }
source.close( );
target.close( );
out.println("<HTML><HEAD><TITLE>文件上传</TITLE></HEAD><BODY>");
out.println("文件已上传<BR>");
}
catch (Exception e)
{ out.println("文件不能上传<BR>");}
out.println("</BODY></HTML>");
}
// 处理GET请求
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{ doPost(request,response); }
}
请问如何解决，谢谢！
