Cross-platform Java application wrapper for creating Windows native EXEs.
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, a custom process name, and a Java
download page in case the appropriate JRE cannot
be found.
Features (2.x)
- Launch4j wraps jars in
Windows native executables and
allows to
run them like a regular Windows program. It's possible to wrap
applications on Linux!
- 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.
- Process
name as the executable
filename to
easily
identify your application.
- Works with a bundled JRE or
searches for newest JRE / SDK
in
given range.
- Opens Java
download page if an
appropriate Java version
cannot be found.
- Supports GUI
and
console apps.
- Passes command line
arguments, also supports constant arguments.
- Allows to set the initial/max heap size.
- JVM options: set system properties, tweak the garbage
collection...
- Option
to change current directory to the executable location.
- Custom version
information shown by Windows Explorer.
- GUI and command line
interface.
- Build integration through an Ant
task.
- Lightweight: 21 KB!
- It's
free and may be used for
commercial
purposes.
- Includes a sample
application and Ant script
that
automates the
build
process from Java sources to native executable.
- The wrapped program
works on all Windows platforms (98/Me/NT/2K/Xp), launch4j works on
NT/2K/Xp, Linux (developed and tested on FC2).

This program is free software licensed under the

Launch4j may be used for wrapping closed source, commercial

Info
Running Launch4j on other Java enabled platforms is a matter
of getting a binary version of
MinGW
binutils 2.15.90 (
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.
