The document provides steps to create a Windows service using Java that will run in the background. It involves creating a Java project with a main class containing start and stop methods. The project is built into a JAR file and copied to a new folder along with Procrun executables. The Procrun executable is run with parameters to install the Java service, specifying the classpath, start class and methods. This allows the Java code to run as a Windows service that can be controlled through the Services console.
