java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext

之前项目一直可以正常打开，但是现在tomcat启动没问题，reload也没问题，但就是在地址栏里访问的时候出现如下异常：
type Exception report

message java.lang.AbstractMethodError:
javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;

description The server encountered an internal error that prevented
it from fulfilling this request.

exception
javax.servlet.ServletException: java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:343)
javax.servlet.http.HttpServlet.service(HttpServlet.java:728)

root cause
java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;
……

note The full stack trace of the root cause is available in the
Apache Tomcat/7.0.47 logs.
不要说“项目包里引入了：jasper-compiler.jar jasper-runtime.jar jsp-2.1.4.jar 和tomcat中lib下面的包 引起了冲突，去掉即可”，我的项目包里没有这几个文件。求解答！

Answer 1

我用tomcat6 正常,用tomcat7会报这个错,有些人是tomcat6报错,tomcat7正常,所以和tomcat的版本可能有一定关系

Answer 2
