First off, I am not only new to J2ME but am fairly new to Java all together. I first took a java class in my Programing Structures 2 class at a technical college I attend.
I am looking to take my basic applications and applets(some developed through, notepad, some through NetBeans for windows, and some developed from pico on a linux box.) and rewrite my codes to run on a PDA (toshiba e740 running PPC2002 w. out a JVM or VM of any sort). One program is a graphical pie chart program that takes input through an application. There are many others. All that garbage out of the way here are my questions:
1. Can I develope J2ME on a Windows box(this is my preffered method)
2. If so, what software do I need? The J2ME downloads all seem to be linux based. What about JVMs for the PPC, do I need a PPC emulator? What else?
3. Will most basic java programs, ie. mortgage calc, simply run on a JVM enambled PPC or do they need to be recompiled by J2ME?
Please help I am very confused.

Welcome to the JavaRanch, Braian!
1. Can I develope J2ME on a Windows box(this is my preffered method)
Sure you can.
2. If so, what software do I need? The J2ME downloads all seem to be linux based. What about JVMs for the PPC, do I need a PPC emulator? What else?
You need the Sun J2ME Wireless Toolkit (probably version 1.0.4 as I suspect your PDA does not support MIDP 2.0 yet), and an IDE. For mobile development, you might consider Sun ONE Studio Mobile Edition, JBuilder MobileSet, or a combination of <your preferred code editor>, Ant and Antenna.
3. Will most basic java programs, ie. mortgage calc, simply run on a JVM enambled PPC or do they need to be recompiled by J2ME?
Most applications will not. Some *very simple* applications might, except that you still need to repackage them in order to be installed. I'd get a second opinion on that, though.

Hi Braian,
if you want to develop programs that will run on your PDA, the first thing you could do is to buy Daryl�s book: Java Development on PDAs (http://www.amazon.com/exec/obidos/tg/detail/-/0201719541/qid=1064052219/sr=8-1/ref=sr_8_1/102-5542533-2672912?v=glance&s=books&n=507846)
The only missing point in that book is that you can use the Pocket PC Emulator on your computer.
You can use Personal Java to develop for your PDA, which is previous to J2ME but very powerful and most JVM are actually Personal Java implementations. It�s very similar to "normal" Java, but you�ll be missing Swing components.
If you�re interested in the Emulator and so on, let me know and I�ll post all the nessesary information.
Cheers
Fernando
