Question

我已经编写了一个带有Apache tomcat的cod ein eclipse IDE。它运行了fin ethere。但是当我尝试通过Apache tomcat从外部运行它时，我得到以下错误 -

 `exception 
org.apache.jasper.JasperException: Unable to compile class for JSP:

Answer 1

删除此行

<%@ page import="comparision_list.Comaprision"%>

它无论如何都没用过

服务器遇到内部错误，异常是org.apache.jasper.JasperException：无法为JSP编译类
