SUN JAVA VM

SUN JAVA toolkit (Phones and PalmOS)

java

Within the SUN website you will find the JAVA SDK JWTK2.2.
It allows to generate JAVA MIDP1.0 or MIDP2.0 .JAR files which can work with JAVA phones and other JAVA's mobiles. This SDK is very easy to use, lots of Tutorials...
I was using it under Linux, but it seems that SUN stop to maintain Linux version.
The VM for PalmOS is in MIDP1, no MIDP2 version (not yet ?).
JAVA SUN SDK: J2ME Wireless Toolkit 2.2
Last is JWTK2.5Beta version.

TIPS, How to convert .JAR JAVA MIDP for PALMOS with SUN Converter

  • You can use the "Jar To PRC" converter which convert a JAVA .JAR file into an executable for PALM OS. The result is an ApplicationName.prc file. This application required the SUN MIDP for PALM OS JAVA VM to work.
    JAVA MIDP for PALM OS: MIDP4Palm
    - JAVA VM MIDP1.0 .prc for PalmOS 3.5+.
    - Converter Jar to .prc for PalmOS.

    NOTE : This PALMOS VM seems to be old... not able to manage old MIDP2.0 function. Within my PALMOS I detected some bugs with Calendar date management, even if the same Java application works very well under my Java phone (Nokia Symbian phone).

    • IBM JAVA VM

    MIDP2 Version :)

    TIPS, how to convert JAVA .jar to .Prc for PALMOS V5.4+

  • Similar as SUN Converter, but the IBM JarToPrc is more recent and is able to convert advanced J2ME MIDP2 Game API.
    JAVA MIDP for PALM OS: JAVA VM IBM WEME
    - JAVA VM MIDP2.0 .prc for PalmOS 5.4 (+)
    - JarToPrc : Jar to .prc for PalmOS (Tools to be launched under Windows).
