运行jsp时出现的错误：org.apache.jasper.JasperException: Unable to compile class for JSP
E:\jakarta-tomcat-4.0.1\work\localhost\test\bookstore$jsp.java:4: Package database not found in import.
import database.*;

用textpad运行bookstore$jsp.java时，bookstore$jsp.java是我运行jsp产生的那个java，它说package org.apache.jasper.runtime does not exist import org.apache.jasper.runtime *,这不是java自带的包

好像是缺少apache的一个什么lib包吧，以前也遇到过，具体怎么解决的忘了，好像加了一个什么包就好了。也有可能是jdk里的某个包。
有个叫jasper-runtime.jar的，不记得是什么里面的了
database是你自己订义的包吧?
当引入自己订义的包的时候要注明具体是哪个类,
如:import database.MyDatabase;
你试一下
