java bean问题 调用不了包中的java类!!!!!!

Question

这个应该是classpath的问题吧！

Answer 1

你的包如果肯定没问题的话，可以把包放到tomcat\classes或者tomcat\common\classes目录下试试

Answer 2

web-inf/classes下面
如果你的web-inf下面没有，自己建一个就行了
不行的话，再发帖

Answer 3

F:\resin-2.1.9\doc\shop\WEB-INF\classes
把user包放到这个目录下面

Answer 4

大家好！我的user在了web-inf\classes下
情况依旧

Answer 5

你的check.java里有没有这句话：
package user;

Answer 6

<jsp:useBean id="check" class="user.check" scope="page"/>

Answer 7

为什么不能用短一点的程序test呢？
