spring hibernate jpa: class not found - spring

Question

i try to implement dao layer with hibernate implemantation of jpa , but somehow i get ClassNotFoundException for my own class, which is surely situated in specified location.
listings:
jpa dao :
package com.foo.testapp.daoImpl
#Repository
public class JNewsDaoImpl implements NewsDao{
#PersistenceContext()
private EntityManager eManager;
#Resource
UserTransaction uTransaction;
#Override
public List<News> listNews(boolean isrus) throws DAOTechnicException,
DAOLogicException {
System.out.println("in jpa");
CriteriaBuilder cb = eManager.getCriteriaBuilder();
CriteriaQuery<News> cQuery = cb.createQuery(News.class);
Root<News> rootEntry = cQuery.from(News.class);
CriteriaQuery<News> all = cQuery.select(rootEntry);
TypedQuery<News> allQuery = eManager.createQuery(all);
return allQuery.getResultList();
}
//etc
}
package com.foo.testapp.service
#Service("newsService")
public class NewsServiceImpl implements NewsService {
#Autowired
private NewsDao dao;
public void setNewsDao(NewsDao newsDao) {
this.dao = newsDao;
}
public void getNewsDao(NewsDao newsDao){
this.dao = newsDao;
}
#Override
#Transactional
public List<News> listNews(boolean isrus) throws DAOTechnicException, DAOLogicException {
//NewsDaoImpl dao = new NewsDaoImpl();
List<News> listNews = new ArrayList<News>();
listNews= dao.listNews(isrus);
return listNews;
}
//etc
}

so any ideas, please?

Answer 1

The XML configuration package names does not match the actual ones.
In XML you have com.epam..., while inb Java sources you have com.foo....
EDIT:
Please check if you have any other exception beforehand. It seems like you're creating beans using both annotations - #Repository - and XML Spring configuration.
