To install a java vm , a compiler and runtime library.

== Pre-requisites ==

Need to have these packages installed

task-native-sdk

opkg install task-native-sdk

== Installation ==
As root on a running gumstix with internet access.

If you don't have internet access on your gumstix, you can download the packages and copy them to the gumstix via usb drive.
May take a few goes to get all the dependencies.

first add angstrom repo
echo 'src/gz angstrom-base http://www.angstrom-distribution.org/feeds/unstable/ipk/glibc/armv7a/base'
> /etc/opkg/angstrom-base.conf

Install class path
opkg install classpath
opkg install classpath-dev

If you need the graphical classes
opkg install classpath-gtk

If you are using graphical classes/gui remember to export the display
export DISPLAY=:0.0

Install cacao vm
opkg install cacao

Install jikes java compiler
opkg install jikes

If you need a java vm with debuging or remote debugging support or wish to use the phoneme jvm
wget http://bugcommunity.com/downloads/files/phoneme-advanced-personal-debug_mr2-r1_armv6.ipk
opkg install -force-depends phoneme-advanced-personal-debug_mr2-r1_armv6.ipk

Once everything is installed and your ready to run.

Set the bootclass path so jikes can find the classes
export BOOTCLASSPATH=/usr/share/cacao/vm.zip:/usr/share/classpath/glibj.zip

then with the standard java hello world
vim Hello.java
/* Hello.java */

public class Hello
{
public static void main(String[] args)
{
System.out.println("Hello world!");
}
}

Save then compile
alxx@omap1:~$ jikes Hello.java
alxx@omap1:~$ ls
Hello.class Hello.java

Run it using cacao
alxx@omap1:~$ java Hello
Hello world!
alxx@omap1:~$

Run it using phoneme
alxx@omap1:~$ java-cdc Hello
Hello world!
alxx@omap1:~$
