Hi, Some time ago I failed the Developer certification (117/154). My score: Section Summary Report: General Considerations: Maximum=58 Deductions=5 Actual=53 Documentation: Maximum=20 Deductions=2 Actual=18 GUI: Maximum=24 Deductions=12 Actual=12 Server: Maximum=53 Deductions=19 Actual=34 Total: Maximum=155 Deductions=38 Certification Score=117 As can be seen I lost most in the server part. I have now replaced RMI by object serialization and am now ready to upload the new version of the application. As I understand the FAQ at http://suned.sun.com/US/certification/faq/, I am not going to retake the essay. My question is now: How does Sun handle the fact that the resubmission and the essay does not match on choice the network communication? Has anybody been in this situation? Best regards PS: I have fixed the GUI as well.
