Rome Exception,

[vaibhav mishra]

I am using Rome 1.0 library to fetch some feed from the net , it is just a beginner program, here's the code

 try{
        var feedUrl:URL=new URL("http://javalan.blogspot.com/feeds/posts/default?alt=rss");
        var input:SyndFeedInput = new SyndFeedInput();
        feed = input.build(new XmlReader(feedUrl));
    }
    catch(ex:Exception){
        ex.printStackTrace();
        println('Error : {ex.getMessage()}');
    }

it is the javafx equivalent code

and I get this error
