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.

Doesn't extract the jar from the executable.

Custom application icon with multiple resolutions and color depths.

Native pre-JRE splash screen in BMP format shown until the Java application starts.

Initial priority and single application instance features.

Works with a bundled JRE or searches for newest Sun or IBM JRE / JDK in given version range and type (64-bit or 32-bit).

Opens Java download page if an appropriate Java version cannot be found or a support website in case of an error.

Supports GUI and console apps.

Supports Windows application manifests.

Passes command line arguments, also supports constant arguments.

Allows to set the initial/max heap size also dynamically in percent of free memory.

Info

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.
