You Need To Install JRE (Java Runtime Environment , Not Open JDK) !

Download It From http://www.filehippo.com/download_jre/

You Need To Install 1.7.x Versions

After Installing JRE Just Run run.bat

Still In Development !

==================================================

it's based on the sources of Ipk Packager and jpkg-webos but with so many changes

run.bat is for Windows but as you know you can run a jar file in any operating system (Mac OS , linux , ...) because it's Java

i did compile it with Java 7 so you need JRE 1.7.x

enjoy creating ipk files
