This is Sundar. I should have written EJB3.0 exam. Actually i have good knowledge in EJB2.0 only. I didn't prepare EJB3.0. I took Sun voucher at 4500/-. If any body wouldlike to write SunCertificationExam(SCJP,SCWCD,SCBCD,etc...), you can purchase at me. Voucher Expired date April 2009. I think i would be unable to prepare for the exam. So i would like to sell my voucher.
