Hi Prajakta Acharya,
I never got that certification, the reason? Spring!
I started working with Spring some years ago and I do not think it is worth it to waste your time with EJBs. I do not have the exact figure but it is something like 70% of the Java EE applications that are being developed are developed with Spring, it is flexible, scalable, robust, it integrates well with REST technologies, it has everything you need.
Make long story short, don't bother with any certification from Oracle.. other than the Programmer one.
