Cross-platform Java executable wrapper

Launch4j is a cross-platform tool for wrapping Java applications distributed as jars in lightweight Windows native executables. The executable can be configured to search for a certain JRE version or use a bundled one, and it's possible to set runtime options, like the initial/max heap size. The wrapper also provides better user experience through an application icon, a native pre-JRE splash screen, and a Java download page in case the appropriate JRE cannot be found.

How to use Launch4



This program is free software licensed under the BSD 3-Clause License, the head subproject (the code which is attached to the wrapped jars) is licensed under the MIT License. Launch4j may be used for wrapping closed source, commercial applications.


Running Launch4j on other Java enabled platforms is a matter of getting a binary version of MinGW binutils 2.22 (windres and ld only) for your system or compiling them. If you'll provide these, I'll be able to create a binary package available for download.
