I saw a lot of people asking this question. I don’t know exactly how much useful it is in job, but I can use my experience to let you get the idea.
Ever since I got SCJP and SCWCD, and put my resume on monster and yahoo hotjob, I got emails everyday about offering me a job and also get calls from time to time. Some of the consulting service directly tell me that they see I have SCWCD certificate.So you see the point, it brings you more opportunities.
Also it is a terrific way to learn Java Web development. It is true that some of the people who owe the certificate can not write even a very simple web app. So it can not prove that you are an expert of Web development, but it does show that you have a lot of knowledge in this area.
It is a great thing you should get if you have time.
