有一处错误在su.initialize(pageContext);说initialize()方法没定义，开始以为是我下的包有问题，结果换了几个还是这样。分不多了，请好心人帮忙。

不知道 没出现你这种情况 你写在servlet里面试下：：
package com.globalarts.util;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.jspsmart.upload.SmartUpload;
import com.jspsmart.upload.SmartUploadException;
public class UploadFile extends HttpServlet {
private static final long serialVersionUID = 1L;
private ServletConfig config;
private String folderpath = " ";
private String filepath = " ";
final public void init(ServletConfig config) throws ServletException {
this.config = config;
}
@SuppressWarnings( "deprecation ")
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setCharacterEncoding( "gbk ");
String dtstr = " ";
String url = " ";
String fileurl = " ";
int rd =0;
SmartUpload su = new SmartUpload();
int rs = 0;
su.initialize(config, request, response);
su.setMaxFileSize(1024 * 200);
su.setAllowedFilesList( "jpg,jpeg,gif,bmp,JPG,GIF,BMP,JPEG ");
try {
su.upload();
} catch (Exception e) {
rs = 2; // 文件上传失败
}
if (rs != 2) {
com.jspsmart.upload.File file = su.getFiles().getFile(0);
try {
file.saveAs(fileurl);
} catch (SmartUploadException e) {
e.printStackTrace();
rd =1;
}
if(rd==0){
PrintWriter out = response.getWriter();
out.print( "上传成功！ ");
out.close();
}
else{
PrintWriter out = response.getWriter();
out.print( "上传失败！ ");
out.close();
}
}
else{
PrintWriter out = response.getWriter();
out.print( "上传失败，请检查图片格式与大小(200K以内)！ ");
out.close();
}
}
}
