tomcat cannot be resovled to a type

Question

tomcat下是应该把自己编写的类放在web-inf/classes中吧，为什么却提示说找不到类呢？

Answer 1

是把.class文件放到WEB-INF/classes目录下，问题就是找不到这几个类的.class文件，所以报cannot be resolved to a type 错误

Answer 2

是没有找到class的，但是应该怎么弄呢？

Answer 3

JSP页面要引入你用到的类..
<%@ page contentType="text/html; charset=gb2312" import="java.util.*,java.sql.*"%>
引入的类文件写在import=""里,引入多个类用逗号隔开.

Answer 4

我引入了呀
<%@ page import="analyzer.*"%>
<%@ page import="org.apache.lucene.analysis.*"%>
<%@ page import="org.apache.lucene.queryParser.*"%>
<%@ page import="org.apache.lucene.search.*"%>
<%@ page import="org.apache.lucene.document.*"%>
<%@ page import="org.apache.lucene.analysis.standard.*"%>
<%@ page import="Search.*"%>
<%@ page import="java.util.*"%>
<%@ page import="org.apache.lucene.search.highlight.*"%>

Answer 5

你把项目中用到的jar包放到WEB-INF\lib目录下，你再试试看

Answer 6

检查一下你的WEB-INF是大写还是小写？  必须是大写的
+webroot
----WEB-INF
--------classes
--------lib

Answer 7

检查一下你自己编写的类放在哪里,路径是否和你引入的路径一样..你用什么工具编写的jsp?如果是用MyEclipse,应该会有错误提示的..
