    • Uses an INI file for specifying classpath, main class, vm args, program args.
    • Custom executable name that appears in task manager.
    • Additional JVM args for more flexible memory use.
    • Built-in icon replacer for custom icon.

    JSmooth

    JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself.

    JexePack

    JexePack is a command line tool (great for automated scripting) that allows you to package your Java application (class files), optionally along with its resources (like GIF/JPG/TXT/etc), into a single compressed 32-bit Windows EXE, which runs using Sun’s Java Runtime Environment. Both console and windowed applications are supported.

    – JexePack’s website

    JexePack is trialware. Payment is required for production use, and exe files created with this tool will display "reminders" without payment. Also, the last release was in 2013.

    InstallAnywhere

    InstallAnywhere makes it easy for developers to create professional installation software for any platform. With InstallAnywhere, you’ll adapt to industry changes quickly, get to market faster and deliver an engaging customer experience. And know the vulnerability of your project’s OSS components before you ship.

    InstallAnywhere is a commercial/enterprise package that generates installers for Java-based programs. It’s probably capable of creating .exe files.

    Executable JAR files
