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

2.如果jsp页面报如下异常

.apache.jasper.JasperException: java.lang.ClassNotFoundException: .apache.jsp.Customer.addCustomerInfo_jsp
.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:177)
.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:369)
.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390)
.apache.jasper.servlet.JspServlet.service(JspServlet.java:334)
javax.servlet.http.HttpServlet.service(HttpServlet.java:722)
.springframework.orm.hibernate3.support.OpenSessionInViewFilter.doFilterInternal(OpenSessionInViewFilter.java:198)

.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:96)
.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76)

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。
