I've tried to run PocketDesign on a SLC-860, but I've run into problems instead. The application wouldn't launch, intepreter complains that class "java.io.StringBufferInputStream" cannot be found (NoClassDefFoundError).
Research has lead me to Java Programming Guide:
which explains that J2ME PP doesn't support some of Java features that were previously available in PersonalJava (such as java.io.StringBufferInputStream).
It seems that on some Zaurus machines (like SL-5500) the original Java was PersonaJava (Jeode by Insignia) with an option to install J2ME PP (from Sun).
Unfortunately SLC-860 is equipped only with J2ME PP, and applications that do not conform to it would not run... Sharp site has some explanations, unfortunately in Japanese:
If you have an idea how to get PersonalJava running on on SLC-860, please share it.
