jsp怎么调用Servlet的参数 应该是很简单的问题！

Question

我想实现一个upload.jsp上传的页面。在upload.jsp页面中点击上传后，转到showFileName.jsp页面。在showFileName.jsp页面中显示上传文件的名字及上传的时间。
现在我不知道怎么把FileUpload.java 中得到的name 传给showFileName.jsp页面。请专家指教
代码如下：
package com.searchforyou.upload;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.PrintWriter;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Iterator;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.commons.fileupload.servlet.ServletRequestContext;

/**

• Servlet implementation class for Servlet: FileUpload

  public class FileUpload extends javax.servlet.http.HttpServlet implements
  javax.servlet.Servlet {
  private HttpServletRequest req;
  private HttpServletRequest resp;

  protected void doGet(HttpServletRequest req, HttpServletResponse resp)
  throws ServletException, IOException {
  PrintWriter out = resp.getWriter();
  resp.setContentType("text/html;charset=gb2312");

  final String HOMELINK = "<a href=\"http://localhost:8080/SearchForYou/pages/showFileAddContent.jsp\">hhhhh</a><br/>";
  
  boolean isMultipart = ServletFileUpload
          .isMultipartContent(new ServletRequestContext(req));
  String uploadPath = "";
  String newFileName = "";
  File writeFile = null;
  
  if (isMultipart) {
      try {
          uploadPath = "D:\\Tomcat 5.5\\webapps\\resources";              
          DiskFileItemFactory factory = new DiskFileItemFactory();
          factory.setSizeThreshold(1000000);
          factory.setRepository(new File(uploadPath));
  
          ServletFileUpload upload = new ServletFileUpload(factory);
  
          List items = upload.parseRequest(req);
          Iterator iter = items.iterator();
          while (iter.hasNext()) {
              FileItem item = (FileItem) iter.next();
  
              if (!item.isFormField()) {
                  [color=red]String name = item.getName().replaceAll(".+\\\\", "");//得到文件的名字，把它传给showFileName.jsp[/color]                     
                  //System.out.print(name);
                  //String type = item.getFieldName();
                  String type = item.getContentType();
  
                  System.out.print(type);
                  long size = item.getSize();
                  if ((name == null || name.equals("")) && size == 0) {
                      continue;
                  }
                  SimpleDateFormat fmt = new SimpleDateFormat(
                          "yyyyMMddhhmmssSSS");
                  newFileName = fmt.format(new Date()) + "_" + name;
                  writeFile = new File(uploadPath, newFileName);
                  item.write(writeFile);
                  //set.attribute(name);
                  out.println(HOMELINK + "上传成功");
                  //out.println(type);                                              
                  out.println(name);
              }
          }
      } catch (FileUploadException e) {
          out.println(HOMELINK + e.toString());               
      } catch (FileNotFoundException e) {
          out.println(HOMELINK + e.toString());               
      } catch (IOException e) {
          out.println(HOMELINK + e.toString());
      } catch (Exception e) {
          out.println(HOMELINK + e.toString());
      }
  
  }
  

  }

  protected void doPost(HttpServletRequest req, HttpServletResponse resp)
  throws ServletException, IOException {
  doGet(req, resp);
  }
  }

下面howFileName.jsp部分内容 ，[color=red] value="" 里面显示 FileUpload.java 中name的值（上面红色部分）。[/color]

添加内容信息

<!-- id的表单域 -->

ID：

Answer 1

在FileUpload 中
[code="java"]
String name = item.getName().replaceAll(".+\\", "");//得到文件的名字，把它传给showFileName.jsp

[/code]
之后
[code="java"]
req.setAttribute("name", name);
[/code]
然后在howFileName.jsp中
[code="java"]
value="<%=(String)request.getAttribute("name")%>"
[/code]

大致就是这样的。
