Copying JNLP app to computer lacking Internet access

How might I go about running a JNLP app on a machine that has no Internet access? Is there a way to copy the app's files from a mac开发者_JS百科hine where the app has already been downloaded and run?

A better solution is to request a .jar file download that you can run with java -jar program.jar because the files that are stored after the launch of the .jnlp isn't really "readable", you will find that resources and classes names are somewhat obfuscated.

A project named jnlpdownloader does this task, download from the jnlp all dependencies and creates executables.
