Short summary and practical advice for (and who has the corporate requirement): there are three sensible approaches to turn a JAR into something Windows users can double‑click or deploy centrally. Each has tradeoffs, and is right that wrapping a JAR into an EXE reduces Java's portability — choose based on deployment needs.

If the goal is a supported, enterprise-ready installer that bundles a runtime, use the JDK tooling path: produce a minimal runtime with jlink and create a platform installer/launcher with jpackage (JDK 14+; stable in later JDKs). Example jpackage usage:

jpackage --input input-dir --name MyApp --main-jar myapp.jar --main-class com.example.Main --type exe --icon myicon.ico --app-version 1.0.0

This yields native launchers and installers (MSI/EXE on Windows) and is good for SCCM/GPO distribution when combined with code signing.

If startup time and removing the JVM dependency are primary goals, consider GraalVM native-image. It produces a true native binary with fast startup and lower memory use but requires explicit configuration for reflection, dynamic proxies, JNI, and some frameworks.

If a simple double-clickable launcher is enough, wrapper tools (for example Launch4j, JSmooth, WinRun4J or packr) can be quicker. They still rely on a JRE unless you bundle one.

Practical cautions: prefer a redistributable OpenJDK build when bundling runtimes and check vendor licensing, sign installers/executables to avoid SmartScreen warnings, test on clean VMs (no JREs installed), match 32/64-bit targets, and verify working directory and resource loading (common pitfalls). For head‑office deployments, produce an MSI or signed installer and test silent install options.

Hi bhoop and welcome to DaniWeb :)

There are tools out there that allow you to create an exe from a java application. However this defeats one of the main advantages of java, portability. You would need a pretty good reason to go down that path, I believe...

Thank you for starting this thread, bhoop.

Hi darkagn, I need to convert a jar to an exe as well.
I have no idea why, it's a request from our headoffice.

One programme that looks handy is exe4j.

Could you suggest any other apps that will be able to do this?

Thanks!
