Hi guys:

take a look at the testWrapper shell script in the bin directory of  
the delta pack distro used by the Java Wrapper Service to detect OS  
and architecture information.

http://wrapper.tanukisoftware.org

here's a snippet from that open source project:

# Resolve the os
DIST_OS=`uname -s | tr [:upper:] [:lower:] | tr -d [:blank:]`
case "$DIST_OS" in
     'sunos')
         DIST_OS="solaris"
         ;;
     'hp-ux' | 'hp-ux64')
         DIST_OS="hpux"
         ;;
     'darwin')
         DIST_OS="macosx"
         ;;
     'unix_sv')
         DIST_OS="unixware"
         ;;
esac


# Resolve the architecture
DIST_ARCH=`uname -p | tr [:upper:] [:lower:] | tr -d [:blank:]`
if [ "$DIST_ARCH" = "unknown" ]
then
     DIST_ARCH=`uname -m | tr [:upper:] [:lower:] | tr -d [:blank:]`
fi
case "$DIST_ARCH" in
     'amd64' | 'ia32' | 'ia64' | 'i386' | 'i486' | 'i586' | 'i686' |  
'x86_64')
         DIST_ARCH="x86"
         ;;
     'ip27')
         DIST_ARCH="mips"
         ;;
     'power' | 'powerpc' | 'power_pc' | 'ppc64')
         DIST_ARCH="ppc"
         ;;
     'pa_risc' | 'pa-risc')
         DIST_ARCH="parisc"
         ;;
     'sun4u' | 'sparcv9')
         DIST_ARCH="sparc"
         ;;
     '9000/800')
         DIST_ARCH="parisc"
         ;;
esac
