Question

这是我的第一个问题，所以我希望能够清楚。我正在开发一个简单的JavaFX应用程序，它唯一要做的就是显示一个Web用户界面。一切似乎都没问题，我从Eclipse导出了Runnable JAR文件，我在Window 10和7上测试了它，但是当我把jar放在Window XP操作系统上时，我有以下内容：

这是我的代码：

        stage.setMinHeight( 600 );
        stage.setMaximized( true );
        Scene scene = new Scene(new Group());

        WebView browser = new WebView();
        WebEngine we = browser.getEngine();

        //setting personalized context menu
        browser.setContextMenuEnabled( false );
        //createContextMenu( browser );

        //preventing bug when maximmizing
        stage.maximizedProperty().addListener(new ChangeListener<Boolean>()

        });

        //intercepting javascript alert
        browser.getEngine().setOnAlert( new EventHandler<WebEvent<String>>()

        ScrollPane sp = new ScrollPane();

        sp.setFitToHeight( true );
        sp.setContent(browser);

        //loading and showing content
        we.load("https://www.google.it/");

        stage.show();
    }

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

希望有人帮助我，谢谢！

Answer 1

升级到最后一个JDK 121后，我今天遇到了这个问题。同样的问题是早期发布JDK 122。

至于现在WebView和HTMLEditor在使用JDK 77时可能正常工作（可能还有一些更新版本（如下面链接中所述 - 102），但我没有检查它）。问题是加载库NativeLibLoader.loadLibrary（＆＃34; jfxwebkit＆＃34;）; 有一些模糊的建议，一些新的Microsoft Visual C ++ Redistributables可能会有所帮助。

编辑。它已经在bug报告中了：https://bugs.openjdk.java.net/browse/JDK-8170084并且，唉，以决议结束：＆＃34;赢得了修复＆＃34;。

因此，剩下一个选项 - 为Windows XP提供捆绑的JRE版本1.8.0_102或更低。

Answer 2

因此，剩下一个选项 - 为Windows XP提供捆绑的JRE版本1.8.0_102或更低版本。另一个临时脏选项：将应用程序与1.8.0_102中的jfxwebkit.dll捆绑在一起，并在创建WebView实例之前在代码中添加某个地方（例如，在start（Stage primaryStage）方法中）

if ("Windows XP".equals(System.getProperty("os.name"))){ 
System.load(ABS_PATH_TO_JFXWEBKIT_DLL + "\\jfxwebkit.dll");}

Java WebView在Windows XP上生成异常
