To get sun-java up and going head into your ubuntu software center and click edit/software sources. Click other software and check the canonical partners to enable it.and then close it.
Open up the terminal and run
sudo apt-get update
then
sudo apt-get install virtualbox-4.0
then
sudo apt-get install sun-java6-jre
after that is done you need to set it by running this next
sudo update-alternatives --config java
and pick this line
'/usr/lib/jvm/java-6-sun/jre/bin/java' by picking the number that goes to it.
Now if you are on a 64bit system you need to run this if you are on 32bit don't do it.
sudo apt-get install ia32-libs
If you happen to have installed palm-novacom before installing ia32-libs, then you must restart palm-novacomd:
sudo stop palm-novacomd
sudo start palm-novacomd
now download the novacom-32bit or 64bit and the SDK
when done cd into the directory of the downloaded packages and run this
sudo dpkg -i palm-sdk_3.0.0-svn486609-pho643_i386.deb
and then this
sudo dpkg -i palm-novacom_1.0.76_i386.deb
for 64bit run
sudo dpkg -i --force-architecture palm-sdk_3.0.0-svn486609-pho643_i386.deb
and then this
sudo dpkg -i --force-architecture palm-novacom_1.0.76_amd64.deb
when done type
palm-emulator
to start Web-os. Have fun.
