Context context = new InitialContext();
PaysDao pa = (PaysDao) context.lookup("PaysDaoJpa/remote");
Pays = pa.findAll();
} catch (NamingException e) {
e.printStackTrace();
}
return Pays;
}
*/
public DataModel getPaysDataModel() {
try {
Context context = new InitialContext();
PaysDao pa = (PaysDao) context.lookup("PaysDaoJpa/remote");
