Hi,

 

The problem was in syntax in rss=2.0

Should be rss_2.0

Hi Colleagues,

 

I create RSS feed. When I execute the main class I receive following exception:

in thread "main" java.lang.NoClassDefFoundError: org/jdom/JDOMException

    at com.sun.syndication.io.SyndFeedOutput.<init>(SyndFeedOutput.java:44)

Line 56 is SyndFeedOutput output = new SyndFeedOutput(); //line 56

I send also my class. For the project I use Rome library.

Can somebody advise how to resolve it.

 

 

 

 

public class CreateRSSFeed {

 

private static final DateFormat DATE_PARSER = new SimpleDateFormat("yyyy-MM-dd");

 

 

    public static void main(String[] args) {

   

        try{

        System.out.println("Create RSS feed test");   

        String feedType ="rss=2.0";

        String fileName = "feed.xml";

       

        SyndFeed feed = new SyndFeedImpl();

        feed.setFeedType(feedType);

       

        feed.setTitle("ABC");

        feed.setLink("http://www.abc.com.html");

        feed.setDescription("IT ");

        System.out.print("Feed title is: "+feed.getTitle());

       

        List entries = new ArrayList();

        SyndEntry entry;

        SyndContent description;

       

        entry = new SyndEntryImpl();

        entry.setTitle("About ABC");

        entry.setLink("http://www.abc.com/category.php?categoryID=3681");

        entry.setPublishedDate(DATE_PARSER.parse("2011-01-10"));

        description = new SyndContentImpl();

        description.setType("text/plain");

        description.setValue("ABC is blablabla..");

        entry.setDescription(description);

        System.out.print("Entry title is: "+entry.getTitle());

        entries.add(entry);

       

        feed.setEntries(entries);   

       

        Writer writer = new FileWriter(fileName);

        SyndFeedOutput output = new SyndFeedOutput(); //line 56

        output.output(feed, writer);

        writer.close();

                   

        System.exit(0);

       

        }catch (Exception ex) {

                ex.printStackTrace();

            }   

    }

 

}
