关于jsp页面使用jstl的异常分析

1.在jsp页面中使用如下代码加入jstl的支持
代码如下:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

2.如果jsp页面报如下异常
org.apache.jasper.JasperException: java.lang.ClassNotFoundException: org.apache.jsp.Customer.addCustomerInfo_jsp
org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:177)

那么很有可能是你的Tomcat的lib目录中没有jstl的jar包，所以才导致tomcat无法解析jstl
解决方案:在tomcat的lib目录中添加jstl的jar包即可。
