Hi Everyone, We have created a new industry leading exam! The Sun Certified Developer for Java(TM) Web Services certification exam. The certification exam number for the beta: 311-220. The FREE beta starts on April 29 � May 23, 2004 and worldwide registration begins on April 28, 2004. You can start to send an email to sunbeta@Prometric.com as of Monday, April 12, but you WILL NOT be able to register to take the exam - with your electronic voucher - until April 28. You CANNOT register for the beta online. To get a free voucher: Send an email to: SunBeta@Prometric.com Subject Line: SCDJWS Voucher Include in your email... Full name: Country: Web Services Experience: Email: Prometric id number: Confirm you have passed the Sun Certified Programmer (prerequisite) PLEASE ALLOW 5-7 BUSINESS DAYS FOR A RESPONSE, DO NOT SEND DUPLICATE EMAILS. This exam does have a prerequisite, Sun Certified Programmer (any version), you MUST have passed this certification to take the beta. If you take the beta and do not have the prerequisite you will NOT receive your certification package and will NOT receive a score until you have passed the prerequisite. I will send you the scheduled time (hours) for the exam and how many questions next week. If you pass the beta exam, you will receive your full certification package (including a lapel pin, ID card, business card logo and the certificate itself) from Sun upon the formal release of the certification in the SUMMER of 2004. The cost of a certification voucher is normally $150. Please DO NOT send emails asking about the status of your score.

Just sent an email to apply for the voucher. Thanks Javaranch. I've got a lot of help from Javaranch with my certification road: SCJP, SCJD, SCBCD and SCWCD. I've seen a lot of guys as me to discuss questions, to share experience, to help each other, and to celerbrate our achievement! Although my present job does not focus on Java, but we're planing to leverage Java more and more in the near future. Here is another month of hard studying ahead for SCDJWS, but I enjoy it. Cheeeeeers,
SCJP 91% SCJD 94% SCBCD 98% SCWCD1.4 86%<p>XML141 SCDWJS -- in progress<br />If you don't retreat, you are mostly among those who can surmount it.

Hello hover I think that the emails will be looked after Monday 12... Please read above... I'm waiting for Monday... Bye
Hi Eduardo, I have emailed a request for the voucher. But I did not participated in the survey conducted by Sun. Do they still consider me?? I am really intersted in this. Is there a sure way to get the voucher for the free beta? Thx, bye. sk
There is no need to participate in the survey to get a voucher! And dont worry you'll get one as long as you dont send an email on the last day that is Most people apparently just get one and then dont take the exam, as was apparent in the SCMAD Beta :roll: Please people, only ask for one if you really intend to take the exam, so that this doesnt turn into another SCMAD extension! And if you decide not to take it after receiving one, please return it to Sun. This way everyone gets a fair chance! Nart [ April 11, 2004: Message edited by: Nart Seine ]

What is prometric id number? i passed SCJP long back, and all i have is candidate no., is it same as prometric id number?
Great News Evelyn. Thanks. Looking forward to take the exam. Evelyn, one question for you. I do not have much experience in webservices, but am very much interested in taking the exam. Am I eligible for free voucher too? If so, then I want to know the relative hardness of exam compared with SCWCD 1.4 Beta. SCWCD 1.4 Beta was much tough compared to SCWCD 1.3. Looking forward to your reply...Thanks.
Is this voucher for those who plan to take the exam between the dates of April 29 � May 23, 2004 ?
Could we purchase the voucher now and take the test after the 23th of May.
You can always purchase the voucher for taking the exam after it is released to the public. However, for me, the beauty of beta exams are free of charge, although I get only a small time period to study. Nick
Hello, Well in response to my email sent for requesting a voucher, i got an automated response that basically advertises the availability of a beta, and giving the same instructions evelyn gave as how to send a request. :roll: So should i just send another request? Anyone got this response? Nart
Nart, I sent a reply to my invitation from SunBeta@thomson.com (as the email I received said I could) and received a response that my mail was undeliverable. I then sent a second one to SunBeta@prometric.com but did not receive an automated message. What about everyone else? I read from another forum here that someone got their voucher in 2 days.
