NullPointerException in _jspInit

I got a NullPointerException in the _jspInit function in my jsp page while I access it from the web browser by typing in the address. I search the web and most of them said that this is because in my WEB-INF/lib folder, there is the .jar file jsp-api.jar confilicted with the jar file of the tomcat container like in java.lang.NullPointerException at org.apache.jsp.page_jsp._jspInit in Tomcat 6, but works in Tomcat 7. However, I check the lib folder and find no such jar files. What's the cause and how to fix it?

Here's the jsp error page:

type Exception report

Assuming the JAR is the correct direction to go with - I would check to see if it appears in the common.loader property in your catalina.properties file (located under the conf) directory.
