Pooja,
When you are happy with your MIDlet (i.e. it compiles, it has no bug any more
and it works), you JAR (with jar) it and write de JAD file (
Java Application Descriptor). Once you have them both, you have to somehow convert them to something that the PALM OS will understand. To achieve that we have a nice little application in the midp4palm package called Concerter. You just have to start it. Then you use the Converter to retrieve the JAR and JAD files (which must be in the same directory). Once you are in the right directory you select the JAD file (by means of file chooser) and click on the "Convert" button.
This creates a new file called "something.prc" and there you go.
So as you can see, there is really no difficulties in doing that. The PRD file is just a few clicks away...
MIDP4PALM package Rob,
yes I do J2ME development, too. I find it very interesting and challenging since sometimes you have to go back to the olds days and make sure your application is not too demanding and hungry.
Basically, a MIDlet is a small application designed to run on Java-enabled devices like cell-phones, pager, handhelds, etc...
A MIDlet is generally a subclass of the abstract class javax.microedition.midlet.MIDlet. The latter declares some abstract methods (startApp,pauseApp,destroyApp) that you have to implement. Those methods are invoked by the underlying OS. So you have to make sure that you provide a body for those abstract methods and that's pretty much it. You have several primitive GUI classes that you can use to make up the user interface which is organized almost like a CardLayout. You can also use networking primitives to make connections to the outside world. Finally, devices provide storing capabilities, so that you can use their ROM to store a limited amount of things you MIDlets need.
I hope this clear thins up a bit...
