openbravoPOS runs in linux and windows. Download openbravoPOS (you can find the link above) Create a database and name it (whatever database name you want to call it), then download the mySQL connector "http://dev.mysql.com/downloads/connector/j/5.1.html". Place the mySQL connector inside the "lib" folder the POS directory. Run the program... In linux you can run the POS using command line, go to the POS directory and execute in shell "start.sh".
