Your /WEB-INF/lib, or worse, your JRE/lib or JRE/lib/ext, is polluted with servletcontainer-specific libraries like jsp-api.jar of a different and older-versioned servletcontainer make/version. You need to get rid of them in your webapp's /WEB-INF/lib. Those libraries are supposed to be already provided by the servletcontainer itself, which is in your case Tomcat.

In your particular example, the javax.servlet.jsp.PageContext.getELContext() method, which exist since JSP 2.1 only, is requested by Tomcat's internal classes, but it could not be found in the JSP API, because you've an older versioned one (apparently JSP 2.0 or older) in your webapp which got precedence in classloading over Tomcat's own one.

In other words, your Tomcat 7 was running like as tomcat 5.5 or older all the time until you upgraded JSTL to a Tomcat 6 compatible one.

Sounds like versioning problem,maybe a conflicting jar file of some sort. See this may help.
