struts关于文件上传，总是出错，哪位大哥帮忙看看？该怎么解决

package com.itcast.action;

import java.io.File;
import java.io.IOException;

import org.apache.commons.io.FileUtils;
import org.apache.struts2.ServletActionContext;

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

public class FileUpLoadAction extends ActionSupport{

    private File image;
    private String imageFileName;
    
    
    @Override
    public String execute() throws Exception {
        String realPath =  ServletActionContext.getRequest().getRealPath("/images");
        System.out.println(realPath);
        File savefile=new File(new File(realPath),imageFileName);//
        if(!savefile.exists()){
            savefile.getParentFile().mkdir();//如果文件夹不存在，在创建一个文件夹
        }
        
        FileUtils.copyFile(image, savefile);
        return "success";
    }


    public File getImage() {
        return image;
    }


    public void setImage(File image) {
        this.image = image;
    }


    public String getImageFileName() {
        return imageFileName;
    }


    public void setImageFileName(String imageFileName) {
        this.imageFileName = imageFileName;
    }
    
    
}
