public syndfeed generate() {     syndfeed feed = new syndfeedimpl();     feed.setfeedtype( "rss_2.0" );     feed.settitle( "my site" );     feed.setlink("http://example.com");     feed.setdescription("test site.");      list<syndentry> entries = new arraylist<syndentry>();     syndentry entry = null;     syndcontent description = null;      entry = new syndentryimpl();     entry.settitle( "entry1" );     entry.setlink( "http://example.com/entry1" );     entry.setpublisheddate( new date() );      description = new syndcontentimpl();     description.settype("text/html");     description.setvalue( "this content of entry 1." );     entry.setdescription( description );      entries.add( entry );     feed.setentries(entries);      return feed; }
