用smartupload上传文件时死机
SmartUpload su = new SmartUpload();
System.out.println( "new SmartUpload is ok ");
su.initialize(pageContext);
System.out.println( "su.initialize is ok ");
su.upload();
System.out.println( "su.upload is ok ");
到su.upload();这里就不往下执行了，cpu100%
为什么
------解决方案--------------------
su.save()这个方法没调用!
------解决方案--------------------
只是读取了文件流，但没有输出保存到硬盘上！
------解决方案--------------------
是不是没设置这个参数？ENCTYPE= "multipart/form-data "
------解决方案--------------------
jspsmartupload的例子：
sample1.htm
<HTML>
<BODY BGCOLOR= "white ">
<H1> jspSmartUpload : Sample 1 </H1>
