Method Detail

launchCompleted
public void launchCompleted(ApplicationInstance application)
Description copied from interface:LaunchHandler
Called when an application, applet, or installer has been launched successfully (the main method or applet start method returned normally).- Parameters:
application
- the launched application instance
-
launchError
public void launchError(LaunchException exception)
Description copied from interface:LaunchHandler
Called when the application could not be launched due to a fatal error, such as the inability to find the main class or non-parseable XML.- Parameters:
exception
- to be re-thrown as launch error
-
launchStarting
public void launchStarting(ApplicationInstance application)
Description copied from interface:LaunchHandler
Called when an application, applet or installer is ready to start. Good point to hide the splash screen.- Parameters:
application
- the application instance that is ready
-
launchInitialized
public void launchInitialized(JNLPFile file)
Description copied from interface:LaunchHandler
Called when an application, applet or installer has been determined. We have some very basic information about the application at this point, but do not have everything required. This is a nice point to show the splash screen.- Parameters:
file
- the JNLP file of the instance that is starting
-
launchWarning
public boolean launchWarning(LaunchException warning)
Description copied from interface:LaunchHandler
Called when launching the application can not be launched due to an error that is not fatal. For example a JNLP file that is not strictly correct yet does not necessarily prohibit the system from attempting to launch the application.- Parameters:
warning
- exception to be consummed as warning- Returns:
- true if the launch should continue, false to abort
-
validationError
public boolean validationError(LaunchException error)
Description copied from interface:LaunchHandler
Called when a security validation error occurs while launching the application.- Parameters:
error
- to be rethrown as launch error- Returns:
- true to allow the application to continue, false to stop it.
