Souza, that's exactly what the topic I posted is saying. There are no books for JSP 2.2 and EL 2.2. There are JCP specifications and some rather short chapters in i.e. SCWCD Study Companion 2nd edition.
I am preparing for JSP & Servlets for JEE 6 exam using books for SCWCD 5 and JCP specifications as a reference material.
