You don't need to install Forte, you just need a text editor. When you run the toolkit and create a new project the toolkit creates a bunch of files for you and an empty src directory. Place your Java source files in there and then press the build button.
Of course, the toolkit assumes you know how to program applications for the Mobile Information Device Profile (MIDP). Go to http://java.sun.com/products/midp and from there you'll find links to tutorials and so on that will help you out. Or buy a book, like my new one.

No, there is no downloadable version of the book. However, a sample chapter from it and two sample chapters from my previous J2ME book are available for download at http://www.j2medeveloper.com -- you might want to grab them to get a better idea of what J2ME is about.
No, you don't have to adjust your paths for the J2ME Wireless Toolkit. Install it, and then go to your Start menu and find its folder and run the "KToolbar" application. This is your "command station" for using the Toolkit.

i,am confused on ceratin topics . I want to get the concepts into my head first and then go for a book purchase. I need your help on this , please .

(1) What is the dif between midp development and developing wireless applications with j2me toolkit ?
(2) Does developing midlets a part of midp ? ...... if yes , then what do we develop using j2me ?
I would really appreciate if you enlighten me on this one please .
Thanks a ton

Why don't you read the sample chapter from my book, then, it's "Java 2 Micro Edition Basics" and it should help with the terminology. But to answer your questions: the J2ME Wireless Toolkit is free software from Sun that lets you currently build MIDP applications. It may be expanded in the future to support further J2ME profiles, but for now it's pretty much MIDP-focused. But any Java development tool can be used for MIDP development. The toolkit is nice in that it integrates all the pieces. But you can get similar things for Forte (well, that's just the toolkit, really), JBuilder, CodeWarrior, etc.
MIDlets are MIDP applications.

Thanks for the information . I think i,am getting the whole idea behind j2me ( slowly ) . Why i,am asking you to solve these petty queries in the beginig is that i can understand the concepts better when i purchase the book .
What all i've understood from your posts and some pdf's which i've dowloaded is that j2me like j2ee is a platform on which we develop wireless applications using j2me toolkit which helps us in the development to midp applications ( i.e the MIDlets .)..... am i right ?
So when we talk about j2me , we actualy are talking about midp application ..... is that so ?
Tell me one more thing ...... IF we are ultimately developing midp application , then is it not better to buy a book on midp rather than j2me .

thanks once again for your patience .

raghav, why don't you do like I said and download the sample chapter from my book? It's free, it's in PDF format, and it will answer a lot of your basic questions. You can download it from http://www.j2medeveloper.com/midpbook/index.html. Read it first, it's not too long, and then I can answer any further questions you have. (But to answer one question: no, J2ME != MIDP. MIDP is just one part of J2ME, although right now it's the most active part. But J2ME includes things like PersonalJava, so there's a wide variation in terms of the capabilities of J2ME applications and the Java environments they run in.)

Well, I'm not going to say no about you buying my book, am I? :-)
Seriously, I do think my book is a good buy for anyone interested in MIDP development. You can read more about it at http://www.j2medeveloper.com/midpbook/index.html -- look closely at the detailed table of contents to see what's covered. I received good feedback on my first J2ME book and you'll probably start seeing detailed reviews of this one showing up on Amazon now that it's been out enough for people to have read it.

Hello guys... Very interesting stuff that i've been reading in this topic. I'm even newer in this topic but thanks for the URL's, i'm looking forward to read all this stuff and perharps buy your book. I've got a question: I'm planning to create a small program in java that stores people's profiles (what they want to receive in their wireless devices). So, for example, if I like to be alerted for stock changes, this information will be sent automatically to my mobile. This "new technology" is called Wireless JMS middleware (you can read it at softwired). am I screwing up all the concepts? is it feasible to develop a very small application like that (it could even be a prototype)?? it should be, but is it too complex to use in conjuction with JMS?? is J2ME going to help me at all?? what tools do you guys recommend me to use?
thanks in advance.

You can download a copy of WHITEBoard SDK, It's designed specially for J2ME development,and it's free. but it has so many many bugs.
