JSP throw NullPointException error in the line

Today I found JSP throw NullPointException error in the following line 

_el_expressionfactory = _jspxFactory.getJspApplicationContext(getServletConfig().getServletContext()).getExpressionFactory()

I found delete

jsp-api-2.1.jar

can fix the issue, but don't know why. Anyone knows the reason for this error.

I am using Tomcat 6.0.33

Web apps must not provide their own Java EE libraries; they will conflict with the server's versions. It can create a variety of errors like this.
