Hi Preethi
JSP is much easier than EJB and stuff. So, I would suggest SCWCD. Take up the book Head First Servlets and JSP by Bryan Basham,Kathy Sierra and Bert Bates (the best book for version 1.4) and the readers of the book are guaranteed a score of 85% and above
Questions of EJB in SCWCD... I doubt
Version of certification matters... if a new version comes up, then you are required to take up an Upgrade exam...

Subba Pradeep,
SCJP 1.4
