Java Software on USB Key

Question

I wrote a Java software. Now I want to copy it on a USB key and make it able to run in a stand-alone way on computers that probably don't have JVM. Is this possible?

Sure there is. Don't listen to the spoil sports. launch4j lets you bundle your executable jar, any dependency jars, and even a JRE into an executable file.

There is, unfortunately, no way to make one cross-platform solution, because JRE implementations themselves are not cross-platform.

You could try a Java to EXE program, like Exelsior JET.

For each computer/architecture you want to run your java code on you need a JVM.

You could provide several JVM's next to your java code for different architectures.

Or you can create an executable for a specific platform (such as MS Windows) see How do I create an .exe for a Java program?

Wikipedia has a collection of Portable Application Creators. If that's an overkill, just use a private JRE.

If you need to save space on your USB key, have a look at this 7-Zip SFX trick (works for both private JRE and Excelsior JET.)
