* 5) Go in oasis-vm folder
* 6) Use 7zip to compress by tar the bin folder in a bin.tar file
* 7) Use 7zip to compress by tar the jvm folder in a jvm.tar file
* 8) Hook your phone up to your computer and load the bin.tar and jvm.tar files onto your USB partition.
* 9) unplug your device from USB port
* 10) Launch Novaterm program <BR>
http://www.webos-internals.org/wiki/Novacom_on_Windows <BR>
http://www.webos-internals.org/wiki/Novacom_with_Windows_7 <BR>
http://www.webos-internals.org/wiki/Novacom_on_Fedora_15 <BR>
with the following command line :
 novacom -t open tty://
Your prompt will change to root@castle:/# ?[J
* 11) Go in the USB folder on your device
 cd /media/internal
* 12) uncompress the files :
 tar xvf bin.tar
 tar xvf jvm.tar
 cd bin
 chmod 755 *
 cp -p * /usr/bin
 cd ..
 chmod -R 755 jvm
 cp -p -r jvm /usr/lib
* 13) Now, check if your Java OasisVM JVM (JRE) works :
 javahy --help
and you should have :
 OasisVM: Build 107
