1、加载页面index.jsp:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>

word = function() {
  var localDir="c:\\temp\\"; // ��ر��ʱĿ¼
  var docName;// ��ر��ļ��, ҲΪ�ϴ��ʱ��ļ��
  var docUrl; // Զ��ļ� e.g. http://128.96.172.238:9080/aaa/upload/aaa.doc
  var uploadUrl; //�ϴ��url
  var savedPath;
  var fso;
  {
   fso = new ActiveXObject("Scripting.FileSystemObject");
   if (!fso.FolderExists(localDir)) {
    fso.CreateFolder(localDir);
   }
  }
  this.openDoc = function(docName, docUrl) {
   this.docName = docName;
   this.docUrl = docUrl;

   if (typeof(docUrl) == 'undefined' || docUrl == '' || docUrl == null) {
    document.getElementById('Mydso').CreateNew("Word.Document");
   }else{
    document.getElementById('Mydso').Open(docUrl,false);
    setfile(localDir+docName);
   }
   document.getElementById('Mydso').Save(localDir+docName, true);
  }

  this.setUploadUrl = function(uploadUrl){
   this.uploadUrl = uploadUrl;
  }

  this.saveDoc = function(){
<%--   alert(localDir+this.docName);--%>
   document.getElementById('Mydso').Save(localDir+this.docName, true);
   document.getElementById('upload').src = localDir+this.docName;

   //打开制定的本地文件
<%--   document.all.Mydso.Open(localDir+this.docName);--%>
   //制定用Word来打开c:\plain.txt文件
<%--   document.all.Mydso.Open(localDir+this.docName,false, "Word.Document");--%>

   document.getElementById('Mydso').HttpInit();
   document.getElementById('Mydso').HttpAddPostCurrFile("FileData", this.docName);
   document.getElementById('Mydso').HttpPost(this.uploadUrl);
<%--   alert(0);--%>
  }

  this.getTempFile = function()
  {
   return localDir+this.docName;
  }

  this.close = function(){
   document.getElementById('Mydso').close();
   try{
    fso.DeleteFile(localDir + this.docName);
   }catch(err){}
  }
}

var word = new word();
    word.setUploadUrl("http://127.0.0.1:8080/word/upload.jsp");

function openfile()
{
  var path = document.getElementById('upload').value;
  document.all.Mydso.Open("http://localhost:8080/word/upload/1.doc",true);
}
function upload()
{
   word.saveDoc();

   var path = document.getElementById('upload').value;
   document.all.Mydso.Save(path,true);
  return true;
}

function load(){
         //方法：openDoc(docName, docUrl)
         // docName:必填，本地保存的文件名, 也为上传到服务器上时的文件名
         // docUrl: 填时，为从服务器端获取doc文档的路径, 不填时，表示本地新建doc文档
         //word.openDoc('zhwm.doc');
         word.openDoc('1.doc','http://127.0.0.1:8080/word/1.doc');
     }

     function save(){
         word.saveDoc();
         word.close();
     }

  var WshShell=new ActiveXObject("WScript.Shell");

  function setfile(path){
<%--   alert('yy='+path);--%>
   setTimeout('document.all.upload.focus();WshShell.sendKeys("tgtrg");',20);
  }
</script>
</head>

2、处理页面uoload.jsp

<%@page
import="com.jspsmart.upload.SmartUpload,org.apache.struts2.dispatcher.multipart.JakartaMultiPartRequest"%>
<%@ page language="java"
import="java.util.*,java.io.*,java.lang.reflect.*,org.apache.commons.fileupload.*,org.apache.commons.fileupload.disk.*"
pageEncoding="UTF-8"%>

<html>
<body>
  <%
   Class<?> multi = request.getClass();
   Field personNameField = multi.getDeclaredField("multi");
   personNameField.setAccessible(true);
   JakartaMultiPartRequest partRequest = (JakartaMultiPartRequest) personNameField
     .get(request);

   Class<?> fileClass = partRequest.getClass();
   Field uploadFiles = fileClass.getDeclaredField("files");
   uploadFiles.setAccessible(true);
   Map fileMap = (Map) uploadFiles.get(partRequest);

   System.out.println(fileMap);
   if (null != fileMap && !fileMap.isEmpty()) {
    List<DiskFileItem> fileItem = (List<DiskFileItem>)fileMap.get("FileData");

    for (DiskFileItem diskFile : fileItem) {
     DiskFileItem disk = diskFile;
     File temp = new File("d:\\tewt.doc");
     disk.write(temp);
    }
   }
  %>
</body>
</html>
3、本地处理action

/**
*
*/
package com.test.controller;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.List;
import java.util.Map;

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

import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class UploadAction extends ActionSupport {
private File upload;
private String uploadContentType;
private String uploadFileName;

public File getUpload() {
return upload;
}

public void setUpload(File upload) {
this.upload = upload;
}

public String getUploadContentType() {
return uploadContentType;
}

public void setUploadContentType(String uploadContentType) {
this.uploadContentType = uploadContentType;
}

public String getUploadFileName() {
return uploadFileName;
}

public void setUploadFileName(String uploadFileName) {
this.uploadFileName = uploadFileName;
}

public HttpServletResponse getResponse() {
  HttpServletResponse response = null;
  try {
   response = ServletActionContext.getResponse();
  } catch (RuntimeException e) {
  }
  return response;
}

public HttpServletRequest getRequest() {
  HttpServletRequest request = null;
  try {
   request = ServletActionContext.getRequest();
  } catch (RuntimeException e) {
  }
  return request;
}

@Override
public String execute() throws Exception {

Map<String, Object> map = ActionContext.getContext().getParameters();

  boolean isMultipart = ServletFileUpload
    .isMultipartContent(getRequest());
  if (isMultipart) {// type=multipart/form-data
   DiskFileItemFactory factory = new DiskFileItemFactory();
   ServletFileUpload upload = new ServletFileUpload(factory);
   upload.setFileSizeMax(1024 * 1024);// 设置上传文件的最大容量
   List<FileItem> items = upload.parseRequest(getRequest());// 取得表单全部数据

   for (FileItem item : items) {
    if (item.isFormField()) {// 如果不是文件类型
     // String name = item.getFieldName(); 表单中某个控件的名称
     // String value = item.getString(); 表单中某个控件的值
    } else {
     String filename = item.getName();
     File f = new File(filename); // 保存的文件
     item.write(f);// 保存文件
    }
   }
  } else {

  }
  HttpServletRequest request = getRequest();
  FileOutputStream fos = new FileOutputStream("d:\\"
    + getUploadFileName());
  FileInputStream fis = new FileInputStream(getUpload());
  byte[] buffer = new byte[1024];
  int len = 0;
  while ((len = fis.read(buffer)) > 0) {
   fos.write(buffer, 0, len);
  }
  fos.close();
  fis.close();
  return SUCCESS;
}
}

4、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

</web-app>

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC
