Janel is a free, Open Source Java native executable and launcher for Windows. Launch your Java application just like other Windows executables. Within the configuration file set the location of the JVM, any of the Java system properties such as classpath, and more. A choice of non-console and console applications is available. The process name is whatever you choose for your .exe file. New for Janel 4.x is the ability to use the Janel executable as a Windows service.
I am using it for years now. Easy to handle and very reliable. Now going to check the new "run as a service" feature :-)
