Congrats Arjun,
Well done.... about which exam
you should give next depends what is your choice. if you have experience in web component developer then go for SCWCD. as you might be knowing you have such a wonderful book HF
servlets and
JSP. which makes it very easy to prepare for the exam. but for web services exam i think you just have one certification book. that also amazon.com is taking ages to deliver. you do have other reference books for web services.study notes by mikali Zaikin.
