java - javaFX launch() not working -

im trying set video play in jframe using javafx.

but 1 time phone call launch() function set javafx , play video, next error

exception in application constructor exception in thread "awt-eventqueue-0" java.lang.runtimeexception: unable build application instance: class mvap.mvap_playvideo

does know i'm doing wrong?

public mvap_playvideo() { mvap.checkjframe(); //ensure mvap.jframe still exists, recreate if doesn't jframe = mvap.jframe; //set jframe mvap.jframe mvap.clearframe(); //clear components in mvap.jframe url = mvap.url; //retrieve media url mvap.url initcomponents(); //set new jframe components //get video dimensions //set jframe dimensions video dimensions //jframe.setsize(); launch(); //launch video. programme stops working here. } @override public void start(final stage stage) { final jfxpanel fxpanel = new jfxpanel(); //create new panel. after launch();, it's meant reach here media media = new media(url); //create new mesia final mediaplayer player = new mediaplayer(media); //create new media player //set media player position fxpanel.setscene(new scene(new group(new mediaview(player)), 300, 200)); //set dimensions media dimensions jframe.add(fxpanel); //add panel frame jframe.setvisible(true); //set frame visible player.play(); //play media }

this entire class

the application.launch() method used launch standalone javafx application.

but trying integrate javafx content swing application. please read official oracle documentation:

integrating javafx swing applications

and more:

javafx-swing interoperability

if want add together javafx content swing application, have utilize wrapper jfxpanel add together swing container, , have init javafx panel javafx thread this:

jframe frame = new jframe("swing , javafx"); final jfxpanel fxpanel = new jfxpanel(); frame.add(fxpanel); platform.runlater(new runnable() { @override public void run() { // method invoked on javafx thread scene scene = ...; // create scene fxpanel.setscene(scene); } });
