报如下错误
exception javax.servlet.ServletException: org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: 28 in the generated java file The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory
?
找了好久,发现是web-inf/lib下的jsp-api,servlet-api与tomcat/lib下的包重复,删除就好了。
?
特别是用MVN管理的工程一定要注意。
