java.lang.Objectcom.install4j.api.launcher.ApplicationLauncher
public class ApplicationLauncher
This class allows you to launch an installer application, such as an updater, from your own application. It includes a mechanism for the installer application to shut down the invoking application with a "Shutdown calling launcher" action.
In order to use this class, please include resource/i4jruntime.jar from your install4j installation into your class path. You do not need to distribute this file along with your application, install4j will do this automatically for you.

public static void launchApplication(java.lang.String applicationId, java.lang.String[] arguments, boolean blocking, ApplicationLauncher.Callback callback) throws java.io.IOException
applicationId
- the ID of the installer application to be launched. You can show the IDs of all installer applications on the
"Installer->Screens & actions" tab with the "Show IDs" tool bar button.arguments
- the arguments you want to pass to the installer application. Can be null if no arguments
should be passed. Arguments like -Dkey=value will be passed as JVM parameters, just like when calling the installer
application from the command line.blocking
- if this call should block until the installer application exits.callback
- an optional call back for receiving notifications when the installer application exits or
when the installer application shuts down this JVM. Can be null
java.io.IOException
- if there was an error starting the installer applicationpublic static void launchApplicationInProcess(java.lang.String applicationId, java.lang.String[] arguments, ApplicationLauncher.Callback callback, ApplicationLauncher.WindowMode windowMode, java.awt.Window parentWindow)
The "Shutdown calling launcher" action has a different effect than usual: The whole process will be terminated when the installer application exits. Furthermore, the "Request privileges" action only works for elevating a helper process, not the main process.
