This page gives instructions for setting up the Palm OS Development Suite to also do UML modeling.

1. Download and install the Palm OS Developer suite
2. Download the Java Development tools (JDT)
3. Unzip the JDT.
4. Copy the folder inside the features folder into the features folder in the Palm installation.
5. Copy the folder inside the plugins folder into the plugins folder in the Palm installation.
6. Download the UML modeler plug-in installer.
7. Double click on the installer and it will begin the installation process.
8. Choose as the installation directory the Palm Developer Suite directory that contains the features and plug-ins directories. In my case that was: C:\Program Files\PalmSource\Palm OS Developer Suite
9. You should be ready to model.

To try this out:

1. Start the Palm OS Developer Suite
2. Use Window – Open Perspective to set the Java perspective
3. Use File – New – Project – Java to create a new Java project
4. Use New – Other – UML Diagrams – Class Diagram to create a blank UML Class diagram
5. Try a simple diagram and save it.
