Web Service with Java [closed]

Hy !

I this project. Collect some data from a web site. Like name, email etc.. So I want to make a web service in Java, to collect this data and then insert it into a database.

My question is. After I make the web service, in eclipse. What should I have to do to make the web service automatically !? Without open the eclipse project. When a user insert his data, those information goes directly into the database. How can I make the project run at any time, without my intervention.

I only ask for guidance ! Thanks in advance
