Cxx0 General discussions / Can you modify Zaurus to run normal Java (J2SE or J2EE) app?

Is there a way to run J2SE (Java 2 - Standard Edition... most Java Application on the Internet are this) or even J2EE (Java 2 - Enterprise Edition) on your Zaurus?

Is it simply a matter of adding the missing classes, or do you need to install a new different JVM

In short: the answer is YES.

You can run J2SE on Zaurus. I am doing that, and have some Swing applications happily drawing on the 640x480 screen. Go to http://www.blackdown.org and fetch the j2sdk 1.3.1 for arm. If you want to run Swing you will then also need to install X Window System for Zaurus, and it in turn needs a set of tools which need a set of libraries etc. If you are feeling adventurous, try the excercise. Or you can try going to:
http://www.dimes.tudelft.nl/wimtiwon/COMBINED/zaurus/,  the site of our ingenious Java-enabled sysadmin (he was born on the island of Java:) who made all the packages for java click-install on Zaurus.

There\'s a catch however. Note that the j2sdk version is 1.3.1, so you will have to settle for the classes that existed at the time 1.3.1 was current. It may or may not be a problem. Blackdown people promised a 1.4.x a looong time  ago.

And to answer the second part of your question, just copying the classes from a j2se will not work, although cvm can read them. But it dies either with a security exception or with version unsupported exception when it comes to classes that are not part of the PJAVA profile (i.e. j2me).
