I'm a serious J2ME developer. I bought this book because it claimed to solve the 600 phone problem. It also promised to do some fancy GUI which are otherwise completely lacking in J2ME.
However, right out of the box the first demo, the menu sample, fails utterly. Ant crashed because I didn't put an Ant jar file in the any classpath then the menu sample didn't work. I had to search some forum to find there is a bug in the latest RC4 download. Apparently no one at Enough caught or fixed it. To fix it I had to patch a css file deep inside the project. If that wasn't enough the actual menu demo looked horrible on WTK 2.5. Couldn't see the menu highlights and it scrolled incorrectly.
Then I tried the roadrunner game. But the game didn't fit on the screen properly--isn't this the 600 phone issue? Ultimately, when I tried to exit, the game (or emulator) crashed. I looked at the jar file size and it was a whopping 462 KB on just 1,433 lines of source! Unreal.
I tried the tabbing demo which looked decent and worked well enough but it was 430 KB on just 200 lines of source. This is awful.
J2ME Polish depends on Ant and preprocessing of #ifdefs which were recognized a bad idea when C introduced them 30 years ago. C++ introduced const (and Java, final) partly for this reason. Actually, in J2ME Polish (and NetBeans) they're not #ifdefs but //#ifdefs because Java never bothered, and rightly, with this silliness--and here they are back again. They make the code less readable and they're virtually impossible to debug.
Then there's this matter of integration of the IDE (I use Eclipse) and Ant. I mean, why bother with an IDE if you must still use Ant? Throw in some .css files, too, for good measure. I just don't get it.
Indeed, I'm returning the book for a refund. I had enough from Enough.
