Jamvm seems to be the best option for java on the Pi at the moment.

If you are on debian or raspbian the packages you need are openjdk-7-jre
and icedtea-7-jre-jamvm. To use jamvm use java -jamvm . There is also
a way to edit configuration files to make jamvm the default but I have not
tried this myself, see xerces post at

Note that cacao doesn't work on arm hardfloat currently. It also apparently
has major problems with version 7 of openjdk.
