Ich habe einfachen Code mit Gluon + JDBC. Ich kann diesen Code mit einem Android-Gerät verbinden, aber nicht mit einem iPad.

my build.gradle;

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.6'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
}
dependencies {
    compile 'mysql:mysql-connector-java:5.0.2'
    iosRuntime 'mysql:mysql-connector-java:5.0.2'
}

mainClassName = 'com.mtt8.version15'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        packagingOptions {
            exclude 'META-INF/INDEX.LIST'
        }

        ios {
            infoPList = file('src/ios/Default-Info.plist')
            forceLinkClasses = ['com.mtt8.**.*', 'com.mysql.**.*']
        }
    }
}

und hier ist JavaCode:

private static final String serverIP="192.168.3.188";
    private static final String DB_DRIVER = "com.mysql.jdbc.Driver";
    private static final String DB_CONNECTION = "jdbc:mysql://192.168.3.188:3306/kasse_sql?useUnicode=true&characterEncoding=UTF-8";
    private static final String DB_USER = "root";
    private static final String DB_PASSWORD = "MYPASSWORD";

    public static Connection connection = null;
    public static Statement statement = null;
    public static String SQL = null;

    public static PreparedStatement pst = null;


    public static Connection getDBConnection(){

        try {
            Class.forName("com.mysql.jdbc.Driver");
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }

        try {
            //connection = DriverManager.getConnection(DB_CONNECTION, DB_USER, DB_PASSWORD);
            connection = DriverManager.getConnection("jdbc:mysql://192.168.3.188:3306/kasse_sql?user=root&password=MYPASSWORD&useUnicode=true&characterEncoding=UTF-8");
            msg.setText("Connection is OK");
            return  connection;
        } catch (SQLException e) {
            e.printStackTrace();
            msg.setText("Dont Connection");
        }

        return connection;
    }

Wie ich schon sagte, funktioniert dieser Code mit Android aber nicht auf meinem Ipad.

Ich erhalte folgende Fehler nach. / gradlew launchIOSDevice

Ich habe es mit verschiedenen Verbindungszeichenfolgen versucht, aber das Ergebnis ist das gleiche.

Kann mir bitte jemand sagen, warum mein Code auf dem iPad nicht funktioniert?
