再次问一下这个问题，全部分拿出来酬谢会的人！关于图片上传

很好实现啊，用如上说的jspsmartupload，下载个包，方法都已经写好了

是啊是啊，用jspsmartupload控件，别说图片了，是文件都传上去了，您提到的方法里面也都有，怎么显示图片你总该会吧

也可以用Apache的FileUpload组件

还是用struts的upload好，没有版权问题

To: pensun37(彭帅军)
文件3中下面这句不对吧，
out.print("<image src=http://localhost:8080/examples/temp/第四章/>"+name);应该是out.print("<image src=http://localhost:8080/examples/temp/第四章/"+name+">"); 才对吧吧

To: pensun37(彭帅军)我试着修改写入文件的名字，怎么不行啊？
