JavaFX2.0 webview无法呈现页面？

我在JavaFX2.0中编写了以下代码

import javafx.application.Application; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.layout.StackPane; import javafx.scene.web.WebEngine; import javafx.scene.web.WebView; import javafx.stage.Stage; /** * * @author roger */ public class WebViewDemo extends Application { /** * @param args the command line arguments */ public static void main(String[] args) { launch(args); } @Override public void start(Stage primaryStage) { StackPane root = new StackPane(); WebView x = new WebView(); WebEngine ex = x.getEngine(); ex.load("http://www.google.com"); root.getChildren().add(x); Scene scene = new Scene(root, 300, 250); primaryStage.setTitle("Hello World!"); primaryStage.setScene(scene); primaryStage.show(); } } 

我收到以下错误，我无法弄清楚出了什么问题？

 Jul 03, 2012 11:18:42 PM com.sun.webpane.webkit.network.URLLoader doRun WARNING: Unexpected error java.lang.IllegalArgumentException: Illegal cookie name at java.net.HttpCookie.(HttpCookie.java:158) at java.net.HttpCookie.parseInternal(HttpCookie.java:964) at java.net.HttpCookie.parse(HttpCookie.java:215) at java.net.HttpCookie.access$100(HttpCookie.java:58) at java.net.HttpCookie$12.parse(HttpCookie.java:1096) at sun.net.www.protocol.http.HttpURLConnection.filterHeaderField(HttpURLConnection.java:2605) at sun.net.www.protocol.http.HttpURLConnection.getFilteredHeaderFields(HttpURLConnection.java:2642) at sun.net.www.protocol.http.HttpURLConnection.getHeaderFields(HttpURLConnection.java:2686) at com.sun.webpane.webkit.network.URLLoader.extractHeaders(URLLoader.java:776) at com.sun.webpane.webkit.network.URLLoader.willSendRequest(URLLoader.java:574) at com.sun.webpane.webkit.network.URLLoader.doRun(URLLoader.java:155) at com.sun.webpane.webkit.network.URLLoader.access$000(URLLoader.java:42) at com.sun.webpane.webkit.network.URLLoader$1.run(URLLoader.java:104) at com.sun.webpane.webkit.network.URLLoader$1.run(URLLoader.java:101) at java.security.AccessController.doPrivileged(Native Method) at com.sun.webpane.webkit.network.URLLoader.run(URLLoader.java:101) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) 

请让我知道需要修改什么和出了什么问题？

一些google-fu我发现这个论坛post导致了这个错误RT-15676 。 该post建议添加该行：

 java.net.CookieHandler.setDefault(null); 

应用程序启动后但在启动WebView之前。 所以我在将根StackPane添加到场景之前放置它。 它现在似乎工作。

 import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.layout.StackPane; import javafx.scene.web.WebEngine; import javafx.scene.web.WebView; import javafx.stage.Stage; public class WebViewDemo extends Application { /** * @param args the command line arguments */ public static void main(String[] args) { launch(args); } @Override public void start(Stage primaryStage) { StackPane root = new StackPane(); WebView x = new WebView(); WebEngine ex = x.getEngine(); ex.load("http://www.google.com"); root.getChildren().add(x); java.net.CookieHandler.setDefault(null); Scene scene = new Scene(root, 300, 250); primaryStage.setTitle("Hello World!"); primaryStage.setScene(scene); primaryStage.show(); } }
