I have been so busy with my latest project but I just want to give one quick reply to inform you that I have passed the SCJD exams. I want to take this chance to thanks Roberto Perillo and Roel De Nijs for their quick and helpful support. This is really a great forum !
My SCJD exam is not a smooth journey, I got the assignment in March 2010, have lots of real life project to do since then and have no time to look at it. Fortunately, the project come to a pending state and I have time to read the SCJD book and come to this forums for more guidance and info. However, it still takes me 2 months to complete the assignment. I submitted the project in 7th Mar and waiting but I didn't receive any feedback from oracle so I sent some emails to ask and they said there was some delay...bla bla bla... and finallly on 25 May (after nearly 3 months) I got the email said that I passed. Phew!
Thank you so much everyone. I like this forums mostly because everyone is so friendly and cheerful. My next plan is to have Web Services Certification (SCDJWS/OCPJWSD) so see you around in that sub forums.
