How to change JSP version in Tomcat?

I am upgrading my old Java webapp using JSP spec 2.0 to tomcat 7 that uses JSP specs 2.2 and the EL specs have changed much in recent versions of Tomcat 7. I have a lot of JSPs that uses old EL that are not compatible with newer versions of EL in JSP 2.2.

My question (Futile alert!), can I somehow change Tomcat 7 to use JSP 2.0 spec. You'd say why don't I use older Tomcat; I can't because I need to use Servlet 3.0 specs.

No you can't. If you somehow did, you wouldn't be able to use Servlet 3.0 because your JSP(s) are compiled into Servlets. Tomcat releases are tied to JSP and Servlet versions.

Per the Apache Tomcat 7 documentation,

Apache Tomcat version 7.0 implements the Servlet 3.0 and JavaServer Pages 2.2 specifications from the Java Community Process, and includes many additional features that make it a useful platform for developing and deploying web applications and web services.
