MIDP : Java Glossary

A MIDP application has some jar files each with a MANIFEST.MF, similar to an application manifest and a jad file which lists the midlets and jars for a bundle.

How does Software get into a Cell-Phone?

1. If the phone has Internet access, I presume it is possible to download the jad file (mime text/vnd.sun.j2me.app-descriptor) from an ordinary website given the URL.
2. If the phone has WAP access, you upload the jad file to a host like waphq.net. Your app gets assigned a number. Anyone wanting to load the software uses their cell-phone wap browser to navigate to the site e.g. http://waphq.net/wap.php and enters the number. cellphoto.net is a similar service that creates the jad file automatically, and lets you upload an image/ringtone/midlet. The WAP the server auto generates the jad file from the Manifest.MF file inside the midlet.
3. Each phone may have a proprietary way to upload code over a proprietary cable, sometimes called a conduit, with proprietary software from a desktop computer. For example, for Sanyo, the software is a $30.00 USD add on. Nokia uses PC-Suite. Some phones let you upload with Bluetooth. Some phones let you upload over in infrared link. Some phones look like a USB storage device (flash drive) to the desktop. Some phones you program by plugging a memory card into them that you have loaded with your memory card writer slot.
