First make sure Java runtime is installed on your computer or downlod it from sun at see installation guide below or check http://java.sun.com/javase/downloads/?intcmp=1281
Full installation guide is included in the download files
Both JIP and JIPXt can be run as graphical User interface (GUI) or as a console . Only JIPXt can in addition be run as a service.
You can choose to run JIP or JIPXt as a stand alone program, as a console or as a service (JIPXt only)
Running as GUI: You can run as a stand alone or use the GUI to do the necessary configurations and then close it and run the JIPXt service utility
Running as Console: can be run as stand alone. There is no need to run the service as this is almost the same. But you can still run the service.
Running as a service: The service utility was created to help you run with minimal memory as possible. see the user guide folder included in the download files for guidelines
Running as Cron Job: The best and easier way to run on linux is to use the cron job file. In this file the timer of JIP has been stopped. It is therefore controlled by the cron job utility of the OS.
