digester3解析xml(rss)手写

digester3解析xml(rss)手记
因为需要写个程序解析RSS，于是下载了最新的digester3版本：commons-digester3-3.2-bin.zip
http://commons.apache.org/proper/commons-logging/download_logging.cgi

用以前的惯常写法，一直不行。

一直报这样一个错
public class Channel {private final List<Item> items = new ArrayList<Item>();//@BeanPropertySetter( pattern = "rss/channel/title")    private String title;    //@BeanPropertySetter( pattern = "rss/channel/link")    private String link;    //@BeanPropertySetter( pattern = "rss/channel/description")    private String description;    //@BeanPropertySetter( pattern = "rss/channel/language")    private String language;        //@BeanPropertySetter( pattern = "rss/channel/copyright")private String copyright ;    //@BeanPropertySetter( pattern = "rss/channel/dc:creator")private String creator ;        //@BeanPropertySetter( pattern = "rss/channel/dc:rights")private String rights ;。。。
