I'm testing creating a webjar in .jar for the same desktop, using the NETBEANS - JavaFX Webview sample tool. The code is as shown below. I'm just looking for a way to remove the address field and the "GO" button, leaving the window only with the contents of the blog page, for example.

package webviewbrowser;

import java.util.List;
import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.HPos;
import javafx.geometry.Insets;
import javafx.geometry.VPos;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import javafx.scene.layout.ColumnConstraints;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.Pane;
import javafx.scene.layout.Priority;
import javafx.scene.layout.VBox;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;

public class WebViewBrowser extends Application {

    @Override public void start(Stage primaryStage) throws Exception {
        Pane root = new WebViewPane();
        primaryStage.setScene(new Scene(root, 1024, 768));
        primaryStage.show();
    }


     public static void main(String[] args) {
        launch(args);
    }


    public class WebViewPane extends Pane {

        public WebViewPane() {
            VBox.setVgrow(this, Priority.ALWAYS);
            setMaxWidth(Double.MAX_VALUE);
            setMaxHeight(Double.MAX_VALUE);

            WebView view = new WebView();
            view.setMinSize(500, 400);
            view.setPrefSize(500, 400);
            final WebEngine eng = view.getEngine();
            eng.load("http://www.blogmarciocunha.com.br");
            final TextField locationField = new TextField("http://www.blogmarciocunha.com.br");
            locationField.setMaxHeight(Double.MAX_VALUE);
            Button goButton = new Button("Go");
            goButton.setDefaultButton(true);
            EventHandler<ActionEvent> goAction = new EventHandler<ActionEvent>() {
                @Override public void handle(ActionEvent event) {
                    eng.load(locationField.getText().startsWith("http://") ? locationField.getText() :
                            "http://" + locationField.getText());
                }
            };
            goButton.setOnAction(goAction);
            locationField.setOnAction(goAction);
            eng.locationProperty().addListener(new ChangeListener<String>() {
                @Override public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
                    locationField.setText(newValue);
                }
            });
            GridPane grid = new GridPane();
            grid.setVgap(5);
            grid.setHgap(5);
            GridPane.setConstraints(locationField, 0, 0, 1, 1, HPos.CENTER, VPos.CENTER, Priority.ALWAYS, Priority.SOMETIMES);
            GridPane.setConstraints(goButton,1,0);
            GridPane.setConstraints(view, 0, 1, 2, 1, HPos.CENTER, VPos.CENTER, Priority.ALWAYS, Priority.ALWAYS);
            grid.getColumnConstraints().addAll(
                    new ColumnConstraints(100, 100, Double.MAX_VALUE, Priority.ALWAYS, HPos.CENTER, true),
                    new ColumnConstraints(40, 40, 40, Priority.NEVER, HPos.CENTER, true)
            );
            grid.getChildren().addAll(locationField, goButton, view);
            getChildren().add(grid);
        }

        @Override protected void layoutChildren() {
            List<Node> managed = getManagedChildren();
            double width = getWidth();
            double height = getHeight();
            double top = getInsets().getTop();
            double right = getInsets().getRight();
            double left = getInsets().getLeft();
            double bottom = getInsets().getBottom();
            for (int i = 0; i < managed.size(); i++) {
                Node child = managed.get(i);
                layoutInArea(child, left, top,
                               width - left - right, height - top - bottom,
                               0, Insets.EMPTY, true, true, HPos.CENTER, VPos.CENTER);
            }
        }
    }
}

Simply remove the rows that add the elements to WebViewPane . Since you will no longer use these controls, it does not make sense to keep the instances where the instances are created and the events defined, so this can also be removed.

If you only want one scene with the content of the web page, this is enough:

// Omitindo imports.

public class StackOverflow extends Application {

   public static void main(String... args){
      launch(args);
   }

   @Override
   public void start(Stage primaryStage){

      final WebView webView = new WebView();
      final WebEngine webEngine = webView.getEngine();
      webEngine.load("http://www.blogmarciocunha.com.br");

      BorderPane borderPane = new BorderPane();
      borderPane.setCenter(webView);

      primaryStage.setScene(new Scene(borderPane, 1024, 768));
      primaryStage.setMaximized(true);
      primaryStage.setVisible(true);
   }  
}

I do not remember if BorderPane has scroll bar ... If the above code does not allow scrolling, create ScrollPane to insert webView :

// ...

ScrollPane scrollPane = new ScrollPane();
scrollPane.setContent(webView);

BorderPane borderPane = new BorderPane();
borderPane.setCenter(scrollPane);

primaryStage.setScene(new Scene(borderPane, 1024, 768));

// ...
