Question

I built a java program that consists of 2 files. The one that contains the main is SnortMonitor.java and it uses Database.java to connect to the database and run a query. I migrated it from my windows machine to the linux machine where it needs to be. I am able to compile it and run it just fine on both machines.

My ultimate goal, which is my next step, is finding a way to make this into an executable with will constantly run on this linux machine. The program is designed to scan each record of a database and send certain information to another machine, I need it to run constantly so that it is constantly sending this information to this other machine, or something like every 3-5 seconds.

One Footnote: For some reason that is beyond my knowledge, I ended up with SnortMonitor.java, Database.java, SnortMonitor.class and Database.class once I finished compiling and running on linux, I’m not sure if this makes a difference, I’m very new to linux.

You have two options:

1. Create a start-up script, such as a .sh bash script for example, that launches your java application. See Tomcat startup script for an example.
2. Use GCJ to compile it to machine code, but your application loses portability.

Personally I prefer the first option, but choose what is right for you.
