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. </p> <img style="width: 352px; height: 498px; margin-left: 100px;" src="launch4j-use.gif" alt="How to use Launch4"> <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. </li> </ul> <h2>License</h2> <p> This program is free software licensed under the <a href="http://www.opensource.org/licenses/bsd-license.html">BSD license</a>, the <em>head</em> subproject (the code which is attached to the wrapped jars) is licensed under the <a href="http://www.opensource.org/licenses/mit-license.html">MIT license</a>. Launch4j may be used for wrapping closed source, commercial applications. </p> <h2>Info</h2> <p> 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. </p> <a href="http://sourceforge.net/forum/forum.php?forum_id=332683"></a> </div> <div class="footer"> All trademarks mentioned are properties of their respective owners.<br /> Copyright © 2005-2008 Grzegorz Kowal <p style="margin-top: 2em"> <a href="http://sourceforge.net"><img style="width: 125px; height: 37px; border: none" src="http://sourceforge.net/sflogo.php?group_id=95944&type=4" alt="sf.net"></a> <a href="http://www.nosoftwarepatents.com"><img style="width: 90px; height: 40px; border: none; margin-left: 5%" src="http://www.nosoftwarepatents.com/banners/90x40_3.jpg" alt=""></a> <a href="http://validator.w3.org/check?uri=referer"><img style="width: 88px; height: 31px; border: none; margin-left: 5%" src="http://www.w3.org/Icons/valid-html401" alt="Valid HTML 4.01!"></a> </p> </div> </div> </body> </html>
