Examples on http://docs.oracle.com/javafx/2/deployment/deploy_swing_apps.htm (dtjava.launch, dtjava.embed) are wrong.

'toolkit' is not a property of the Platform but App (you can check it in dtjava.js)
�
�dtjava.embed(

                    {
                                 id : 'sampleApp',
                                url : 'SampleApp_browser.jnlp',
                        placeholder : 'app-placeholder',
                              width : 960,
                             height : 720
                    },
                    {
                        javafx : '2.2+',
                        toolkit: 'swing'
                    },
                    { onGetSplash: function() {} } //disable splash
                );


need to be changed to

�dtjava.embed(

                    {
                                 id : 'sampleApp',
                                url : 'SampleApp_browser.jnlp',
                        placeholder : 'app-placeholder',
                              width : 960,
                             height : 720,

toolkit: 'swing'

                    },
                    {
                        javafx : '2.2+'
                        
                    },
                    { onGetSplash: function() {} } //disable splash
                );

I guess same applies to dtjava.launch example on the same page.

If examples are used like they are, instead of "Swing" launcher "JavaFX" one is used and swing applet never starts.
