Making debian file for java application.

Making debian file for java application.

ㅇ deployed resources
/opt/testApp/bin/testApp.jar
/etc/testApp/testApp.conf
/etc/testApp/log4j.conf

ㅇ Preparation
1. install dpkg-deb
ㅇ install debian packaging
# install macport
https://guide.macports.org/#installing.macports
cd /opt/local/bin
sudo port selfupdate
sudo port install dpkg

brew install dpkg
2. make jar in dist/lib
        3. init file in /testApp/etc/init/testApp.conf

ㅇ Make debian for jar
