Building on the points from , and , here are practical, up-to-date steps and gotchas to get a Java app from Eclipse onto client machines.

Start with a single distributable artifact. Use Eclipse’s export wizard or your build tool (Maven/Gradle) to produce a runnable archive that includes or references all libraries. If you use a build tool, the Shade/Shadow plugins create a single "uber" JAR; Eclipse’s export offers options to either bundle libraries inside the archive or place them alongside it. Pick the option that matches licensing and update expectations (single file is easiest for users; separate libs are easier to patch).

Common runtime problems and fixes:

  • Resources bundled inside the archive must be loaded via the classpath APIs (e.g., getResourceAsStream); code that treats them as regular files will fail.
  • Native libraries (.dll/.so) can’t live inside a JAR unchanged — they must be extracted at runtime or placed on the native library path.
  • When creating an uber-JAR watch for duplicate resources and service-provider files; merge rules may be needed.
  • Test on a clean machine that does not have your IDE or development JRE installed so you catch missing-dependency and version issues.

Installer and native options: if clients are comfortable installing a JRE, distributing the runnable JAR plus a short start script or a small launcher is simplest and cross-platform. If you must produce a native experience, modern JDK tooling can create self-contained runtime images and platform installers, or you can wrap the JAR with a native launcher and use a platform installer—both are platform-specific and add maintenance. Also consider licensing before bundling Oracle JREs; OpenJDK builds are a safer redistributable choice.

Do final validation on each target OS and Java version, sign artifacts if required, and include simple start instructions. Start with a runnable archive to validate functionality, then only invest in native installers if user convenience demands it.

Package it as a jarfile.

In addition to what masijade said:

Write a manifest file which could be as simple as
Main-Class: <MainClass Name>
Version: 1.0

Put this manifest file inside the JAR so that it runs when double-clicked if that's what you are looking for.

if you wanted to know how to put it in a .exe installer, the answer is: don't.
you'll force your users to have a Windows OS installed, which may not always be the case.
