Question

I had completed building a .jar file for me project (media player), it is also running successfully with command line java -jar mediaplayer.jar.

But now i need to make an installer, so what all files do I need for making an installer, do i need to bundle the lib files also with the installer.

also when i launch my .jar file with Java Web Start, it says “Unable to launch application”

Answer 1

You definitely need to bundle both your mediaplayer.jar and the libraries in your classpath. You will also need to generate a native executable file that will at least do java -jar mediaplayer.jar.

Usually native launchers also check if Java is installed on the target machine and help user to install it if it is not.
