eclipse - Java + JavaFX application running when using jdk1.7, errors when using jdk1.8 -

i have been trying develop little java application. i'm using javafx gui. i'm using eclipse e(fx)clipse plugin. worked fine. using jdk1.7.0_60 me default jre in eclipse. decided wanted seek , export runnable .jar file test application without eclipse. went wrong.

a while ago installed jre8 , jdk1.8.0_05 on system, testing purposes. @ first didn't understand why application kept giving runtime errors/exceptions while running application, because default java 8 now.

i changed jdk in eclipse 1.7 1.8 , same errors/exceptions given in eclipse, i'm pretty sure has jave8 i'm running. (combination between 2 maybe?)

it first time using javafx may configuration error.

i've tried changing code explained here still not work. here screenshots , code explain in more detail:

main.java

public class main extends application { public static void main(string[] args) { application.launch(main.class, args); } @override public void start(stage primarystage) throws exception { /* fxmlloader fxmlloader = new fxmlloader(getclass().getresource("/fxml/gui/launcher.fxml")); parent root = (parent) fxmlloader.load(); launchercontroller controller = fxmlloader.getcontroller(); controller.setstage(primarystage); primarystage.settitle("the deep space code"); primarystage.setscene(new scene(root, 600, 400)); primarystage.setresizable(false); primarystage.show(); */ parent root; launchercontroller controller; url location = launchercontroller.class.getresource("/fxml/gui/launcher.fxml"); fxmlloader fxmlloader = new fxmlloader(); fxmlloader.setlocation(location); fxmlloader.setbuilderfactory(new javafxbuilderfactory()); seek { root = (parent) fxmlloader.load(location.openstream()); controller = (launchercontroller) fxmlloader.getcontroller(); } grab (ioexception ioe) { throw new illegalstateexception(ioe); } primarystage.settitle("the deep space code"); primarystage.setscene(new scene(root, 600, 400)); primarystage.setresizable(false); primarystage.show(); } }

launchercontroller.java

public class launchercontroller { @fxml private static webview webview; @fxml private static imageview launchimage; @fxml private static textfield fieldmail; @fxml private static passwordfield fieldpassword; @fxml private static checkbox checkboxsave; @fxml private static button btnlogin; @fxml private static label lblemail; @fxml private static label lblpassword; @fxml private static label lblwelcome; @fxml private static label lblname; private final static string website = "http://5.231.59.222/secret/motd"; private static webengine webengine; private stage stage; private boolean configwrite; private config config; private user user; private string firstname; private string lastname; private string logged; private long session; public void setstage(stage stage) { this.stage = stage; } public void initialize() { configwrite = false; webengine = webview.getengine(); webengine.load(website); platform.runlater(new runnable() { @override public void run() { fieldmail.requestfocus(); } }); // config config = objectprinter.readconfig(); if (config != null) { if (!config.getemail().equals("")) { fieldmail.settext(config.getemail()); checkboxsave.setselected(true); platform.runlater(new runnable() { @override public void run() { fieldpassword.requestfocus(); } }); } } } @fxml protected void loginbuttonclicked(actionevent event) { //removed code since doens't matter , 100+ lines long } @fxml protected void savecheckboxchanged(actionevent event) { configwrite = true; } }

it looks static-fields not filled anymore fxmlloader - why using static variables @ all?
