How to create launcher as windows service using jpackage (Java 19)

As of my knowledge cutoff in September 2021, the jpackage tool introduced in Java 16 does not provide direct support for creating a Windows service. However, you can use third-party utilities to wrap your Java application created with jpackage as a Windows service. One such utility is NSSM (Non-Sucking Service Manager).

Here's an outline of the steps to create a launcher as a Windows service using jpackage and NSSM:

1. Use jpackage to create an executable package of your Java application. Refer to the official documentation for jpackage to create the package for your specific application.

2. Download NSSM (Non-Sucking Service Manager) from the official website (https://nssm.cc/) and extract it.

3. Open a command prompt with administrative privileges and navigate to the directory where NSSM is extracted.

4. Execute the following command to create a Windows service:

   swiftCopy code
   nssm install ServiceName "Path\to\executable.exe"
   
   

   Replace "ServiceName" with the desired name for your service and "Path\to\executable.exe" with the actual path to the jpackage-generated executable file.

5. NSSM will open a graphical interface to configure the service. Fill in the necessary details such as the "Path" to the executable and the "Startup directory". You can also configure additional settings as per your requirements.

6. Click on the "Install service" button to install the service. NSSM will create the Windows service using the provided configuration.

7. Once the service is installed, you can start and manage it using standard Windows service management tools, such as the Services console or PowerShell commands.

Please note that the process of creating a Windows service may vary depending on your specific requirements and the versions of jpackage and NSSM you are using. Always refer to the official documentation and resources for the tools you are using for the most up-to-date instructions and guidance.
