when i run javafx applet in opera it is not working it says
"Content can not be displayed using your Web browser. Please open this page using another browser"
i figured out because of this javafx: '2.2+' in applet parameter this is not working when i remove it. it starts working

dtjava.embed(
                        {
                            url: 'JavaFXApplication2.jnlp',
                            placeholder: 'javafx-app-placeholder',
                            width: 800,
                            height: 600
                        },
                {
                    javafx: '2.2+', // this is creating problem
                    jvmargs: '-Djava.net.preferIPv4Stack=true'
                },
                {}
                );
