How Can I Convert a Java Application into a Windows Service?

Convert Java App to a Windows Service

Question:

You have a Java application and need to install it as a service on Windows. How can you make this conversion?

Answer:

One reliable method is to utilize Apache Commons Daemon. It provides:

• Procrun for Windows services
• Jsvc for Unix daemons

Apache Commons Daemon's permissive Apache license is another advantage. Additionally, Apache Tomcat employs it as part of its Windows and Linux functionality.

Implementation:

Getting Apache Commons Daemon up and running can be challenging. Refer to the comprehensive article linked below for a detailed walkthrough:

Alternative Approach:

Alternatively, you can examine the binservice.bat in Apache Tomcat to understand the service setup process. In Tomcat, the Procrun binaries have been renamed:

• prunsrv.exe -> tomcat6.exe
• prunmgr.exe -> tomcat6w.exe

Caution:

When using Procrun, it's crucial to ensure that your start and stop methods accept the parameters (String[] argv). For instance, "start(String[] argv)" and "stop(String[] argv)" are valid, while "start()" and "stop()" will trigger errors. If your code does not adhere to this convention, consider using a bootstrapper class to tailor the calls to your requirements.
