jsp使用smartupload上传图片的问题

Question

<%@ page import="com.jspsmart.upload.*,java.util.*"%>头文件已经写上了
jar包也已经导入了
<% SmartUpload mySmartUpload=new SmartUpload();
mySmartUpload.initialize(pageContext);
try { mySmartUpload.setAllowedFilesList("jpg,png");
mySmartUpload.upload();
一直提示The method upload() from the type SmartUpload
refers to the missing type ServletException
是什么原因呢 是不是jar包里的文件不全导致的？

Answer 1

refers to the missing type ServletException
缺少这个类型，证明缺少拥有这个类型的java包。
