Dělá toto. UserBusiness je definován ve springu, připojuje se k databázi
přes hibernate a je označen @Transactional.

@Name("authenticator")
public class Authenticator {
@In
Identity identity;
@In("#{userBusiness}")
UserBusiness userBusiness;
@Out(required = false, scope = ScopeType.SESSION)
User logged;
public boolean authenticate() {
Long id = userBusiness.checkUsername (identity.getUsername
(),identity.getPassword ());
if (id!=null && id>0){
this.logged = userBusiness.getById (id);
return true;
}
return false;
}
}

Subject: Re: Chyba při vytváření transakce.
nedela cz.bellman.umm.security.Authenticator neco s Hibernatem?
Martin Chalupa napsal(a):
Zdravím,
přidal jsem do aplikačního kontextu springu beanu, která implementuje
ApplicationListener pro zachytávání událostí v kontextu. A od té doby mi
aplikace vyhazuje chybu při pokusu o vytvoření transakce. Pokud beanu
odeberu nebo zruším implementaci rozhraní vše funguje.
Používám Spring 2.0.6, Seam 2.0 RC3, Hibernate 3.2.4, Session factory je
definovaná ve springu a seam managuje session.
Nenapadá vás nějaká příčina vzniku chyby?
Martin
