Background

This is a short description how Kickstart4J works.
 
  1. User types a JNLP URL or clicks on a link with that URL [less...]
    Java Network Launch Protocol URL in browser address bar
  2. Webstart (JRE >= 1.4.2) loads and starts Kickstart4J [less...]
    Java 1.4 loading splash screen
  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...]
    Optional prompt for destination directory
  5. Kickstart4J copies the necessary application files to user's harddisk [more...]
    File copy dialog
    • 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...]
    Starting the application
  7. Your application (here SwingSet2 example) is running as local installed application [more...]
    SwingSet2
  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());
