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).

Specified by:

launchCompleted in interface LaunchHandler

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.

Specified by:

launchError in interface LaunchHandler

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.

Specified by:

launchStarting in interface LaunchHandler

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.

Specified by:

launchInitialized in interface LaunchHandler

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.

Specified by:

launchWarning in interface LaunchHandler

Returns:

true if the launch should continue, false to abort

validationError

public boolean validationError(LaunchException security)

Description copied from interface: LaunchHandler

Called when a security validation error occurs while launching the application.

Specified by:

validationError in interface LaunchHandler

Returns:

true to allow the application to continue, false to stop it.
