一、问题描述

在项目中引入JxBrowser，然后在Fxml文件中引入JxBrowser的BrowserView控件，文件如下：

<?xml version="1.0" encoding="UTF-8"?>
    
    <?import java.lang.*?>
    <?import java.util.*?>
    <?import javafx.scene.*?>
    <?import javafx.scene.control.*?>
    <?import javafx.scene.layout.*?>
    <?import com.teamdev.jxbrowser.chromium.javafx.BrowserView?>
    
    <BorderPane fx:controller="com.fendo.analysis.jxbrowser.JxBrowserController" xmlns:fx="http://javafx.com/fxml">
        <top>
            <TextField fx:id="textField" text="http://www.baidu.com" onAction="#loadURL"/>
        </top>
        <center>
            <BrowserView fx:id="browserView"/>
        </center>
    </BorderPane>

用JavaFX Scene Builder打开提示如下错误：

二、解决方法

这是由于JavaFX Scene Builder没有识别到JxBrowser，需要将JxBrowser的jar包复制到JavaFX Scene Builder安装目录下的app目录下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTE3ODE1MjE_size_16_color_FFFFFF_t_70][]

在package.cfg文件中加入以下代码：

app.classpath=jxbrowser-6.14.jar

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTE3ODE1MjE_size_16_color_FFFFFF_t_70 1][]

重新打开JavaFX Scene Builder就行了。
