< h2 > Cross-platform Java executable wrapper< / h2 >
< p >
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.

< h2 > Features< / h2 >
< ul >
< li > Launch4j wraps jars in Windows native executables and allows to run them
like a regular Windows program. It's possible to wrap applications
on Windows, Linux, Mac OS X and Solaris!
< / li >
< li > Also creates < strong > launchers< / strong > for jars and class files without wrapping.< / li >
< li >
Supports executable jars and < strong > dynamic classpath< / strong > resolution using
environment variables and wildcards.
< / li >
< li > < strong > Doesn't extract the jar< / strong > from the executable.< / li >
< li > Custom application icon with multiple resolutions and color depths.< / li >
< li > < strong > Native pre-JRE splash screen< / strong > in BMP format shown until
the Java application starts.
< / li >
< li > < strong > Process name< / strong > as the executable filename to easily
identify your application, initial < strong > priority< / strong > and
< strong > single aplication instance< / strong > features.
< / li >
< li > Works with a bundled JRE or searches for newest Sun or IBM JRE / JDK in given
version range.< / li >
< li > Opens < strong > Java download page< / strong > if an appropriate Java version cannot be
found or a < strong > support website< / strong > in case of an error.
< / li >
< li > Supports < strong > GUI and console apps< / strong > .< / li >
< li > Supports < strong > Vista manifests< / strong > and < strong > XP visual style manifests< / strong > .< / li >
< li > Passes command line arguments, also supports constant arguments.< / li >
< li > Allows to set the initial/max heap size also < strong > dynamically< / strong > in percent of free memory.< / li >
< li > JVM options: set system properties, tweak the garbage collection...< / li >
< li > Runtime JVM options from an .l4j.ini file.< / li >
< li > Runtime command line switches to change the compiled options.< / li >
< li > Access to environment variables, the < strong > registry< / strong > and executable file path through system properties.< / li >
< li > < strong > Set environment variables.< / strong > < / li >
< li > Option to change current directory to the executable location.< / li >
< li > The JRE's bin directory is appended to the Path environment variable.< / li >
< li > Custom < strong > version information< / strong > shown by Windows Explorer.< / li >
< li > < strong > GUI< / strong > and command line interface.< / li >
< li > Build integration through an < strong > Ant task< / strong > and a < strong > < a href = "http://9stmaryrd.com/tools/launch4j-maven-plugin/" > Maven Plugin< / a > < / strong > .< / li >
< li > < big > < strong > Lightweight: 26 KB!< / strong > < / big > < / li >
< li > < strong > It's free< / strong > and may be used for commercial purposes.< / li >
< li > Includes a sample application and < strong > Ant script< / strong >
that automates the build process from Java sources to native executable.
< / li >
< li > The wrapped program works on all Windows platforms (98/Me/NT/2K/XP/Vista),
Launch4j works on NT/2K/XP/Vista, Linux, Mac OS X (build on 10.4) and Sparc Solaris 8-10.

Running Launch4j on other Java enabled platforms is a matter of getting a binary version
of < a href = "http://www.mingw.org/" > MinGW< / a > binutils 2.15.90 (< em > windres< / em > and < em > ld< / em > only)
for your system or compiling them. If you'll provide these, I'll be able to create a binary package
available for download.
