Jsp import 預設包class 的問題

在JSP中匯入自訂類，User定義在預設的包下，如下：

<%@ page language="java" import="User" %>

 

然後，

<% User u = new User(); %>

 

運行即出現：

The import User cannot be resolved

 

將User類改成自訂包中的類，如下：

com.test.importclass.User，運行成功。

 

google "jsp import default package",  發現：class一定要寫在包中，如果你珍愛生命的話。

 

"Many people on JavaRanch, including those most prone to answering questions, will quickly lose patience with someone who isn't willing to package all of their classes before trying to debug an issue (any issue), even if packaging doesn't seem to be related to their current problem."
