PRC Converter Tool Tutorial
When you get a Java application written for MIDP, for example from an application provider's website, it will be a pair of files. One file will have a .jar
extension and the other a .jad
extension. The PRC Converter Tool changes the pair of JAR/JAD files into a Palm OS application (a PRC file) so that you can install the application on your Palm OS device.
This tutorial walks you through the conversion and the optional selection of a PRC-file
location. (By default the PRC Converter Tool puts the PRC file in the same
directory as the JAR/JAD files.)
To change a JAR/JAD file pair to a PRC file:
- Make sure the JAR and JAD file are in the same directory.
- Click the PRC Converter Tool's folder icon (
), or choose Convert from its
File menu. A dialog box like the following will appear:

- Navigate to the directory where the JAD and JAR files are located.
- Select the JAD file to convert.
(The JAD info panel shows you information about the Java application.)
- Click the Convert button to convert the JAR/JAD file pair to a PRC
file.
(Convert does not affect the original JAR/JAD files; it merely
creates a new file with a .prc
extension.)
You now have a PRC file ready to install on your Palm OS device.
To specify a directory for the PRC file:
- Click the Preferences button (
) or choose Preferences from the Converter's
File menu. A dialog box like the following will appear:
- Click either:
- Same folder as the JAD file (This is the default.)
- To folder of my choice:
- If you clicked To folder of my choice:, click Browse... and
select the folder from the resulting dialog box:
- Click Use this Folder to make your selection the destination folder
for the PRC files.
- Click Ok to exit the Preferences dialog box and use the directory
that you selected.
