In order to execute a jar file, all you need is a JRE - you can download on Oracles's web site. You can use the JRE that comes inside your JDK too, but remember, not everyone will have a JKD(this is for development), they will probable download a JRE and execute the installation tool. You don't need do make an exe, especially if you have Linux users too. The jar is enough.
