Others will point you to rJava

  http://www.rforge.net/rJava/

which might well be a good solution for you; if you have reasons for
using SJava, then the currently maintained version is at

  https://hedgehog.fhcrc.org/bioconductor/trunk/madman/Rpacks/SJava

accessible using 'svn' and the instructions at

  http://wiki.fhcrc.org/bioc/SvnHowTo

It has not been tested recently on a mac...

> % R INSTALL -c SJava_0.69-0.tar.gz

This should be

  R CMD INSTALL --clean SJava_0.69-0.tar.gz

you require the JDK (Java Development Kit), not just the JRE (Java
Runtime Environment); if you've got the right software installed, you
should be able to find the program 'javah' on your system. 

Hope that helps,

Martin
