Muchos gracias, that explains everything.
meanwhile i looked into my mail:
Effective June 1, 2011, Java, Oracle Solaris, MySQL, and NetBeans certification exams will be offered exclusively through a new test delivery partner — Pearson VUE — and will no longer be available through Prometric.
+ If you are currently following a certification path and are planning to take an exam on/after June 1: Registration will begin at Pearson VUE on May 16, 2011 for all scheduled exams on or after June 1. Visit pearsonvue.com/oracle on or after May 16 to create a new web account and get started.
+ If you are currently registered to take an exam with Prometric or planning to take an exam before June 1: You can continue to register at Prometric through May 23, 2011 (walk-in registrations will be permitted through May 31, 2011), but you must complete your exam by May 31, 2011.
+ If you currently have a Sun or Oracle exam voucher or exam retake voucher: All vouchers will still be valid through their original expiration date and will be redeemable with Pearson VUE starting on May 16, 2011
