To answer the questions: Yes, it relates to Java ME.

As for where to start - I plopped myself down with a copy of Wireless Java: developing with J2ME (2nd edition in my case) and have been slowly working through examples. I'll probably sit for the exam in February or March, once things quiet down in my personal life... but maybe it's time we got together a link page for SCMAD like the other exams too.

The best way to begin in my opinion is get a copy oif wireless Java by Jonathan knudsen, read and practice that for like 2 months, then get some specs from the sun web site specs like MIDp,JTWI read that then get some Exam simulators like whizlabs, then read some more specs and you are good to go

The other thing I'd recommend is to get Sun's wireless toolkit so that you can write lots of test programs - the wireless toolkit is very cool!

I do agree this as well... WTK is the best tool to play around with the sample code... If someone got an IDE that can work together with WTK, then it will be really great as well...

For me, I got JBuilder that can work together with WTK, but there are many times that I just use a pure text editor and WTK itself for testing small applications.

Thanks guys for your advise.

One more intriguing thing is if this knowledge will be at all useful in the practical world. I ask this cos most of the mobiles these days carry Symbian OS and not Java OS.

Hmm...

That's an interesting statement. I really don't know the stats, does anybody have the real stats on this? Following Sun's marketing info it seems like there are hundreds of millions of Java enabled small devices in the world. My personal experience is that there are tons of phones that are Java enabled, and that fact seems to be unknown. On more than one occasion I've asked sales people which of their phones is Java enabled, and they don't even know what I'm talking about

Also, don't be afraid of the specs! Some specs are hard to read, but I think that most of the specs associated with J2ME are pretty user-friendly

That's not my experience at all. First of all, you can always get a JVM for a Symbian phone. That means all Symbian devices are effectively Java devices too.

The reverse is not true. I can't pick up any J2ME handset and add Symbian to it.

Even ignoring that fact, I still think there are way more J2ME devices than Symbian devices world wide. In North American there are practically no Symbian phones at all. Nearly all Sprint and Cingular phones include J2ME. Verizon phones are mostly BREW.

As I know, there is a big difference between mobile opersting system, and if it has java or not.
Symbian OS is the phone OS, then Java (J2ME) comes over that OS, it's just like your PC, it has Windows or UNIX OS and J2SE can be installed on it or not, so the phone = pc, Symbian = UNIX, and J2SE = J2ME.

For an IDE for J2ME, I use Netbeans for J2SE and J2EE projects development, it's very cool
http://www.netbeans.org
Netbeans have a utility called Netbeans Mobility, which is installed over Netbeans, this tool is cool too, it helps me a lot in GUI development, because GUI development is visual, also it helps in flow design, so you can just drag and drop new forms, add navigation buttons, and connects forms to each others for navigation.
For people who are preparing for the exam, I think that you may start by using the wireless toolkit and make many GUI applications, after you tam the GUI APIs, you can switch to netbeans, it will save that long time developing the GUI, and running it to observe changes.
The GUI API for J2ME is pretty easy, Knudsen book is covering everything about it, so you can use it to start development.
