Is there a good starting place for those of us who are new to JSF? In addition to the book, where can we find articles/tutorials/etc?
Thank you,

Nancy,
I believe that is a documented bug in the WTK emulator.
Give it a try with MIDP 2.0 - If you don't have it installed, send me your source code, I'll give it a try.

As we begin the new year, there seems to be a renewed interest in J2ME training.
I am opening this topic to see if there is sufficient interest to offer classroom training within the next few months.
Previous classes have offered:
- 3-day training, covering all aspects of MIDP
- Extensive hands-on labs
- Opportunity to develop/download MIDlets onto an actual MIDP device
- Free copy of the book "Core J2ME Technology"
I would appreciate any feedback regarding interest, suggested course content, etc.
If you have any suggestions, please let me know. You can respond here, or contact me directly:

Thank you!

Hi Layne,
When you have a chance, send me the code you have written. Although I don't have the Linux install, I will run the code on my machine and see if it runs.
If it does, we can decide how to proceed from there.
Thanks,
John

This must be an error with the implementation.
If you look at page 119, you will see the screen shot that I captured (right most figure), showing the result once the event is executed.
What implementation are you using? Feel free to forward the examples to the developers to show the problem.

syed,
I am the author of Core J2ME Technology and MIDP.
The book has received good comments from many readers:
Core J2ME Book at Amazon
If you would like a closer look, you can read the book online (partial contents) at:
Core J2ME book online
Feel free to visit my website, where you can read the back cover of the book, see an enhanced table of contents, and download the source code.
Book information at CoreJ2ME.com
The best way to choose a book (in my opinion) is to visit a book store, grab all the related books, and take some time to read a little from each. Typically it'll be clear which book you prefer.
Best of luck,
John Muchow

This error has to do with using JDK 1.4.x with MIDP 1.0.
You can either install JDK 1.3.x, or try this command line option when compiling:
"javac -target 1.1 ......"

Hi Lance,
Unfortunately, there is no way to access the individual pixels on a Canvas, in MIDP 1.0

Hi Lance,
"Sam's Teach Yourself Wireless Java with J2ME" by Michael Morrison has a few sections on graphics/gaming. Although it is not a book specifically written for gaming, it may give you some additional information along the lines you are looking for.

p.s. Hope the Core J2ME book was helpful.

Hi Rowan,
I am the author of Core J2ME Technology and MIDP. There have been many good reviews written about my book, from experienced as well as new Java developers. Have a look at Amazon:
Core J2ME Technology and MIDP
Also, feel free to ask other readers here about their feedback on the book as well. I am sure a few readers are lurking around
With a little research, I'm sure you'll find the perfect book to meet your needs.

Here is another example that shows how to use session management with cookies and a servlet:

Hi Simon,
Glad to hear you are interested in the book! In addition to Amazon (as Michael mentioned) BN.com and Bookpool.com will also ship internationally.
More good news...the book is being translated into 4 languages (Chinese, Japanese, Korean and Italian). However, I don't know the specifics of when the translations will be available.
Regards,

As another resource, you can visit my J2ME developer site and download source code for a Servlet that uses Cookies to manage sessions with a MIDlet.

I am looking for developers interested in participating in a J2ME/MIDP online training. The course is currently in beta test.
The content closely follows the book
Core J2ME Technology and MIDP
There are 5 topics currently online:
- Basics of J2ME
- CLDC
- MIDP
- Development Tools
- Interactive Compile and Run
I am looking for feedback regarding the content and format of delivery. If there is sufficient interest, additional topics will be created to provide an in-depth look at the entire MIDP API.
If you are interested, please visit: Core J2ME
Thanks,
John

Hi Reuben,
There are many good J2ME books on the market. It really depends on just what you are looking for in a book. Let me give you a quick run down of my intention in writing Core J2ME.
I wanted to write a book that would address all aspects of the API. An in-depth look at the various classes, methods and how to apply the same in writing wireless applications. Examples vary from short and simple to rather involved. An example of the later includes a discussion of session management in detail demonstrating how to use cookies and URL-rewriting to communicate with Java servlets.
Your best best (if possible) is to visit a book store that has several J2ME books and take some time browsing the contents.
Hope that helps.
