Question

如何把JSPsmartUPload的upload.jps页面改为servlet?
我试了两天,都没试成,就是这一句说什么错误,没辙,请大家帮忙!
mySmartUpload.initialize(pageContext);就是这句出错
<%@ page contentType="text/html; charset=gb2312" language="java" import="com.jspsmart.upload.*"%>
<jsp:useBean id="mySmartUpload" scope="page" class="com.jspsmart.upload.SmartUpload" />
<jsp:useBean id="db" scope="page" class="my.dcsky.execSql"/>
<%
// Variables
int count=0;         // Initialization
mySmartUpload.initialize(pageContext); // Upload
mySmartUpload.upload();
//mySmartUpload.setDeniedFilesList("exe,bat,jsp,htm,html,,");
// Select each file
for (int i=0;i<mySmartUpload.getFiles().getCount();i++){ // Retreive the current file
com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(i); // Save it only if this file exists
if (!myFile.isMissing()) { // Save the files with its original names in a virtual path of the web server       
myFile.saveAs("logo/" + myFile.getFileName());

out.println("图片上传成功...");
count ++; } }

%>

Answer 1

SmartUpload su = new SmartUpload();
            PageContext pageContext = JspFactory.getDefaultFactory().
                                      getPageContext(this, request, response, null, true,
                    8192, true);
            su.initialize(pageContext);
            su.upload();
------------------
import javax.servlet.jsp.PageContext;
import javax.servlet.jsp.JspFactory;

Answer 2

好的,谢谢funcreal(为中华之崛起而编程)我回去试试

Answer 3

getPageContext(this, request, response, null, true,8192, true);
这一句是什么意思?

Answer 4

你可以这样su.initialize(config, request, response);
在servlet中定义config
private ServletConfig config;
final public void init(ServletConfig config) throws ServletException {
this.config = config;
}

import javax.servlet.jsp.PageContext;
import javax.servlet.jsp.JspFactory;我改了,这两个包找不到啊,奇怪?帖出来:
package my.sky;import javax.servlet.jsp.PageContext;///////找不到
import javax.servlet.jsp.JspFactory;///////找不到
import com.jspsmart.upload.SmartUpload;
import java.io.*;
import java.util.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;public class dcskyManagerUpSmallProspectus extends HttpServlet{

protected void service(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException{
request.setCharacterEncoding("gbk");
response.setCharacterEncoding("gbk");
PrintWriter out=response.getWriter();

int count=0; 
    SmartUpload su = new SmartUpload();
PageContext pageContext = JspFactory.getDefaultFactory().getPageContext(this, request, response, null, true,8192, true);
su.initialize(pageContext);
su.upload();

     for (int i=0;i<su.getFiles().getCount();i++){ // Retreive the current file
com.jspsmart.upload.File myFile = su.getFiles().getFile(i); // Save it only if this file exists
if (!myFile.isMissing()) { // Save the files with its original names in a virtual path of the web server       
myFile.saveAs("/test/" + myFile.getFileName());
......//省略
db.executeUpdate();
out.println("图片上传成功...");
count ++; } }

   } 
    public void destory() {
  }
}

Answer 8

那为什么
import javax.servlet.jsp.PageContext;///////找不到
import javax.servlet.jsp.JspFactory;///////找不到

Answer 9

在硬盘上search：
upload_jsp.java

Answer 10

你把servlet-api.jar加入了项目的路径了吗?不加入是找不到的......你是用eclipse还是其它的开发工具?

Answer 11

晕,利用jbuilder 或者eclipse起个工程编译就行

Answer 12

RainRainbow() 已经讲得非常清楚了！！private ServletConfig config;
public void init(ServletConfig config) throws ServletException 
{
    this.config = config;
}public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException
{
    SmartUpload su = new SmartUpload();
    su.initialize(config, request, response);
    ...
}
