无法解析类型 org.springframework.dao.DataAccessException。从必需的 .class 文件间接引用了它

如下一个简单的在SPRING中使用HIBERNATE的类，为什么报如题所示错误(出错语句见红色用下划线)
=============================
package Test;

import java.util.List;
import java.util.ArrayList;
import org.springframework.orm.hibernate3.*;

public class BookmarkDAO implements IBookmarkDAO {
private HibernateTemplate hibernateTemplate;

public void setHibernateTemplate(HibernateTemplate hibernateTemplate){
this.hibernateTemplate =hibernateTemplate;}
@Override
public void addUserUrl(String username, String url) {
// TODO Auto-generated method stub
BookMark bm=new Bookmark();
bm.setUsername(username);
bm.setUrl(url);
hibernateTemplate.saveOrUpdate(bm);
}

@Override
public void deleteUserUrls(String username, String[] urls) {
// TODO Auto-generated method stub
for(int i=0;i<urls.length;i++ ){
List<Object> list=hibernateTemplate.find("from Bookmark bm
where (bm.username='"
+username+"') and (bm.url='"+urls[i]+"')");
[size=16px] hibernateTemplate.delete(list.get(0));[/size]
}
}

@Override
public List<Object> findUserUrl(String username) {
// TODO Auto-generated method stub
List<Object> list=hibernateTemplate.find(
"select bm.url from Boolmark as bm where bm.username='"
+username+"'");
return list;
}

}
