您的 JSP 文件中存在错误的导入。

您的日志中有一条明确的消息:

An error occurred at line: [14] in the generated java file: [/usr/local/easy/share/easy-tomcat7/work/Catalina/paykar.co.in/jsp/org/apache/jsp/rechargeMobile_jsp.java] Only a type can be imported. com.RechargeMobile resolves to a package

这意味着您应该有如下一行:

<%@ page import="com.MobileInfo" %>

但这是一个包而不是一个类。 尝试按如下方式更改它以导入包:

<%@ page import="com.MobileInfo.*" %>

否则改变 ir 如下导入你需要的特定类:

<%@ page import="com.MobileInfo.YourClassName" %>
