Today when I was doing something my colleague asked me about what version of JSP and Servlet are you using. Untill now I never bothered about this, but later found a way for this. below are the lines of code to know what version of servlet you are running, version of JSP and application server you are running.
Servlet Version :
<%= session.getServletContext().getMajorVersion() %>.
<%= session.getServletContext().getMinorVersion() %>
JSP Version :
<%= JspFactory.getDefaultFactory().getEngineInfo().
getSpecificationVersion()%>
Server Version : <%= application.getServerInfo()%>

What if the project does not yet compile how do you know what jsp version you are using?

You can basically check inside your JAR's MANIFEST file under /META-INF/MANIFEST.MF
Contents of this file will be as follows:
Name: javax/servlet/
Specification-Title: Java API for Servlets
Specification-Version: 3.0
Specification-Vendor: Sun Microsystems, Inc.
Implementation-Title: javax.servlet
Implementation-Version: 3.0.FR
Implementation-Vendor: Apache Software Foundation
