Very Very Strange Issue - JME3 inside JApplet Inside Browser

Hi

I can run successfully LWJGL applet on my system, as a proof

NinjaCave Applet found here

and here is the screenshot

so it clearly shows that i can run any LWJGL enables applet on my computer.

JME3 INSIDE Applet RUN Directly Within ECLIPSE

Libraries Included,

appletlibs/lwjgl.jar.pack.lzma, appletlibs/jinput.jar.pack.lzma, appletlibs/obf-mmgdesigner-v1.jar, appletlibs/Signed_AbsoluteLayout.jar, appletlibs/Signed_batik-cutdown.jar, appletlibs/Signed_jME3-core.jar, appletlibs/Signed_jME3-desktop.jar, appletlibs/Signed_jME3-lwjgl.jar, appletlibs/Signed_swing-layout-1.0.3.jar, appletlibs/Signed_joal.jar, appletlibs/Signed_j-ogg-oggd.jar


JME3 Canvas Creation and Manipulation Code

[java]
public static void createCanvas(String appClass) {

	AppSettings settings = new AppSettings(true);
	settings.setWidth(1024);
	settings.setHeight(768);
	settings.setSamples(4);
	settings.setBitsPerPixel(24);
	settings.setRenderer(AppSettings.LWJGL_OPENGL_ANY);

	JmeSystem.setLowPermissions(true);

	try {
		Class<? extends Application> clazz = (Class<? extends Application>) Class
				.forName(appClass);
		app = clazz.newInstance();

	} catch (ClassNotFoundException ex) {
		ex.printStackTrace();
	} catch (InstantiationException ex) {
		ex.printStackTrace();
	} catch (IllegalAccessException ex) {
		ex.printStackTrace();
	}

	app.setPauseOnLostFocus(true);
	app.setSettings(settings);
	app.createCanvas();
	context = (JmeCanvasContext) app.getContext();
	context.setSystemListener(app);
	canvas = context.getCanvas();
	canvas.setSize(settings.getWidth(), settings.getHeight());
}[/java]

Start Application method which inserts panel runtime in to Current JPanel

[java]public void startApp() {

	GroupLayout layout = new GroupLayout(previewPanel);
	previewPanel.setLayout(layout);
	layout.setAutoCreateContainerGaps(true);
	layout.setAutoCreateGaps(true);

	layout.setHorizontalGroup(layout.createSequentialGroup().addComponent(
			canvas));
	layout.setVerticalGroup(layout.createParallelGroup().addComponent(
			canvas));

	
	System.out.println(" Starting Canvas ");
	app.startCanvas();
	System.out.println(" Canvas Started ");

	app.enqueue(new Callable<Void>() {
		public Void call() {
			if (app instanceof SimpleApplication) {
				SimpleApplication simpleApp = (SimpleApplication) app;
				simpleApp.getFlyByCamera().setDragToRotate(true);
				simpleApp.getInputManager().setCursorVisible(true);
				validate();
			}
			return null;
		}
	});
}[/java]

and the actual method which calls these two methods

          [java]  createCanvas(jme3AppClass);
	startApp();
	app.setPauseOnLostFocus(false);
	System.out.println("container:init");[/java]

I am running an JApplet then from the Eclipse Run Applet Command

Eclipse Console Output

Now i pack the current Project in Jar , Obfuscate and sign it everything get done successfully.

Following are my Applet Parameters

[java]var attributes = {

};

};
var version = ‘1.6’; // whichever minimum version you want to target, null works also
deployJava.runApplet(attributes, parameters, version);[/java]

When the Applet runs on my computer it does everything normal and execute successfully, i checked in My temp folder there are all the needed jars including natives exist.

JME3 Applet When Runs inside Browser - Java Console Panel

JME3 Applet When Runs inside Browser Screenshot

so what did i make wrong ? i can not see anything in my applet.

<span style=“text-decoration:underline;”>I have few Questions here,</span>

(1) Why the canvas does not display as expected ?

(2) There are some differences i highlighted by drawing box on them specially the Browser Java Console , why is the difference because same code is running on the same computer ?

(3) If you look at the browser Java Console you will see that the camera is created 4 times , Why ?

(4) In my simpleinitapp method at the last i put the line

   [java] System.out.println(" --&gt;  Application Started .......");[/java]

and you can see in the browser Java Console that this line is printed , it means that the method is called and executed successfully ,

still there is nothing on the screen, Why ?

(5) there is no error/ exception stack trace on the browser java console as you can see , what is happening ? anything freezes there ?

I hope i will get answer this time.

Thanks

hi

When i add following Parameter in Applet Configuration,

[java]lwjgl_arguments:"-Dorg.lwjgl.input.Mouse.allowNegativeMouseCoords=true -Dorg.lwjgl.util.Debug=true -Dorg.lwjgl.opengl.Display.allowSoftwareOpenGL=true",[/java]

The following lines appear on the browser java console after this line

<span style=“text-decoration:underline;”>
INFO: Deleting objects and invalidating state</span>

[java][LWJGL] GL_EXT_direct_state_access was reported as available but an entry point is missing
[LWJGL] GL_NV_primitive_restart was reported as available but an entry point is missing[/java]

what does it mean ?
is it the cause for not displaying the canvas ?

Thanks

on my computer the JME Sdk Shows following console Ouput

Using LWJGL 2.8.4 Offscreen buffer created. Adapter: ati2dvag Driver Version: null Vendor: ATI Technologies Inc.

Please anyone can tell me what is the Problem ?

Thanks

That last console output is fine.

I’m seeing missing entry points all the time in my desktop application, which runs fine.
Maybe you could try to release the demo applet and see whether that runs, that would help locating whether it’s a problem in the application or in the outside infrastructure.

Disclaimer: I don’t use applications, so I probably won’t be able to help more.
