Hello! The beta exam is coming! I will post another copy of the revised objectives (they are almost identical to what they were before, except that we've removed a couple of minor things). There is no book out for this exam, of course, although there is an unsubstantiated rumour that Bert and I and Michael Yuan will be working on one... But that doesn't help you for the beta... so we'll put together some sample mock exam questions for each section. I'll have *some* of those up this week. Most of the content is in the MIDP 2.0 specification, the CLDC 1.1 specification (although you are expected to know the major differences between 1.0 and 1.1), the JTWI spec, and a little on WMA and MMAPI. The largest percentage of questions are in the GUI stuff -- low-level/high-level API and also the Game API. Plenty of questions on deployment, and most importantly-- knowing what is and is not guaranteed by the specs for writing portable applications. Again, there is NOTHING that is device-specific. cheers, stay tuned, Kathy
Dear Kathy, maybe you can help answer this question. Thank you so much in advance! Seid Dear Mr. Yuan, it is understandable that there is no book specifically written for SCMAD, but there are other books on J2ME. May I request you to please single out one of the existing books, which will best prepare me for J2ME Beta exam. Since you are one of the creators of the Beta exam I thought that you are in the best position to give your opinion and recommendation. Thank you very much in advance. Seid
Hi Everyone! I'm very excited about the new Sum Certified Mobile Application Developer for the Java 2 Platform, Micro Edition, Version 1.0 certification exam.

Hi, you may have answered this before, but how long from Beta exam to real exam? DOH! You said spring 2004. Now what season would that be around here... winter I guess. The exam specs sound a bit scary - 4 hours and 160 questions? ( ) [ January 27, 2004: Message edited by: Jim Crawford ]
