Background

This is a short description how Kickstart4J works.
 

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

   • 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 (0.7.0)
     • Utils4Swing (0.9.5)
     • 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>

   </application>
   

4. Kickstart4J asks the user for a destination directory (optional) [less...]
   
   
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 [less...]
   
   
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 [less...]
   

   // 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());
