Background

This is a short description how Kickstart4J works.
 

1. User types a JNLP URL or clicks on a link with that URL more...
   
   
2. Webstart (JRE >= 1.4.2) loads and starts Kickstart4J more...
   
   

   • No application specific JARs at this stage
   • Only 6 signed JAR files necessary (All provided by Kickstart4J)
     • Kickstart4j (main)
     • Commons IO (1.4)
     • Commons Exec (1.0)
     • Utils4J (0.6.8)
     • Utils4Swing (0.9.3)
     • Log4J (1.2.9)
3. Kickstart4J loads XML definition for installation more...
   

   <?xml version="1.0" encoding="ISO-8859-1"?>
   <application>
     <version>0.1.0</version>
     <title>Kickstart4J SwingSet2</title>
     <vendor>Future Invent Informationsmanagement GmbH</vendor>
     <description>Local installed SwingSet2 with it's own Java Runtime 1.6</description>
     <exitAfterExecute>true</exitAfterExecute>
     <destPath>c:/fuin.org/examples/swingset2</destPath>
     <idFilename>.org-fuin-examples-SwingSet2</idFilename>
     <silentInstall>false</silentInstall>
     <silentUpdate>false</silentUpdate>
     <locale>en</locale>
     <lazyLoading>false</lazyLoading>
     <logFilename>${destDir}/logs/kickstart.log</logFilename>
     <javaExe>${destDir}/jre6/bin/java.exe</javaExe>
     <javaArgs>-classpath ${classpath} SwingSet2</javaArgs>
     <msgFileUrl/>
     <mkdir path="logs"/>
     <file path="lib" file="SwingSet2.jar" hash="bb8c84a0c833471363a58a75b3a10944" size="1670951" unzip="false" loadAlways="true" addToClasspath="true" srcFileUrl="http://www.fuin.org/examples/kickstart4j/SwingSet2.jar"/>
     <file path="" file="jre6.zip" hash="6657c9fe1f1771c9505bf8760fc120f4" size="24735860" unzip="true" loadAlways="true" addToClasspath="false" srcFileUrl="http://www.fuin.org/examples/kickstart4j/jre6.zip"/>
     <file path="jre6" file="README.txt" hash="f4d7b1802f97b747d921dff10eb533e7" size="15773" unzip="false" loadAlways="true" addToClasspath="false" srcFileUrl="http://www.fuin.org/examples/kickstart4j/README.txt" order="1"/>
   </application>
   

4. Kickstart4J asks the user for a destination directory (optional) more...
   
   
5. Kickstart4J copies the necessary application files to user's harddisk more...
   
   

   • Includes a local JRE which version is completely independent of Webstart's Java version
   • No need to sign any of the application's JAR files!
6. Kickstart4J runs the application using the local installed JRE more...
   
   
7. Your application (here SwingSet2 example) is running as local installed application more...
   
   
8. If required, the started application can use Lazy Loading to load JARs and other files On Demand more...
   

   // Path relative to the installation directory and file to load
   File jar = fileLoader.loadFile("lib", "abc.jar");
   // Add the JAR dynamically to the classpath
   Utils4J.addToClasspath(jar.toURI().toURL());
