回答1：

1.严重: Servlet.service() for servlet jsp threw exception
java.lang.ArithmeticException: / by zero

除数为0错误

2. Cannot retrieve mapping for action /utp

这是不能从action中获取mapping,估计你的action里的mapping和struts配置文件不一致

回答2：

很明显是某个jsp页面出错了仔细检查你的Jsp页面这种错误一般都是jsp页面语法错误导致serv无法编译看看是不是哪里拼错了

回答3：

jsp语法错误。希望下次仔细

回答4：

javax.servlet.jsp.JspException: Cannot retrieve mapping for action /utp 这段，没有/utp这个action；
java.lang.ArithmeticException: / by zero 除数为0了，算术错误。
