I have a number of dependencies that I would like to include in the jar file. I have been looking at the Java Service Launcher (JSVC) that allows me to create a service out of a Java application. I have also looked at the Apache Commons Daemon project. It seems like both of these projects could be used to create a single jar file that would include all the dependencies. The problem is that I can't figure out how to invoke the main method of the Java application. I would like to be able to run it as a service or a stand-alone application. Is there a way to do this using JSVC or Apache Commons Daemon? If not, are there any other tools that would allow me to do this?
