Java Service Wrapper

Question

Dear all,
How could I turn the following java application into a service running under Linux and make it started automatically when the system is restarted using Java Service Wrapper?
The instructions on the Java Service Wrapper website is too complex for me to follow. The application below just write the current time to a file every 5 seconds.
If possible, please give me some step by step instruction about how to configure, install and verify the results.
Thanks
Yu

I suggest you read how to create a startup script in Linux. It doesn't matter that you program is written in java.
