java - Hibernate query and List Object -

i want id table in database, if try id name, have save in list obj, cant use id table again because object , not integer.

my method update table:

public void updateevent (string eventname, string beschreibung, string datum, string ort) {      annotationconfiguration configuration = new annotationconfiguration();     configuration.configure();     sessionfactory sessionfactory = configuration.buildsessionfactory();     session session = sessionfactory.opensession();     transaction transaction = session.begintransaction();      string hql = "select a.eventid admintoolbean a.name = :name";     query query = session.createquery(hql);     query.setparameter ("name", eventname);     list<admintoolbean> results = (list<admintoolbean>) query.list();      system.out.println(results.get(0));     system.out.println(results.get(1));     system.out.println(results.get(2));      admintoolbean event = (admintoolbean) session.load(admintoolbean.class, results.get(0));      event.setname(eventname);     event.setbeschreibung(beschreibung);     event.setdatum(datum);     event.setort(ort);     session.update(event);     transaction.commit();     session.close(); }        

if need id, not object, use simple jdbc. spring has jdbctemplate, or ibatis/mybatis framework.
