Java program runs in the background

Question

I have a simple java program, which is just one piece of code that reads from the database and modifies the contents of the database based on certain conditions. Now I want this program to start automatically when it starts and to silently work in the background if someone has not killed it from the task manager. I had never done anything like this before and I don’t know exactly how to do it. Can someone help me on how to do this? Thanks..

Answer 1

Follow these steps to complete the task: (Assuming you are using windows and jre is installed)

• First compile your Java program and put the class file in one place.
• Now create a bat file and put java LOCATION TO THAT CLASS FILE/MyProgram in it.
• Put your bat file in the launcher
• Reboot the system, you will get your program in the background ..! Hope this helps you.

Answer 2

There are two problems here.

• How to add this program to launch

  • Windows - Run a Java application when Windows starts
  • Linux - running a Linux script for a Java application

• Run the program as a daemon (background process)

  • The easiest way is to use the while and sleep loop for the required time interval in the while loop. Then do the database work.

Also for windows you can check out this JSL http://www.roeschter.com/

Thanks.
