I load the objects with my own adopted query.
public List<Auftrag> getAuftragsliste(Auftragsfilter auftragsfilter) throws
HermesRuntimeException{
List<Auftrag> listeauftraege=new LinkedList<Auftrag>();
// ..... build my query
try{
Query query =em.createQuery(abfrage.toString());
// fill my placeholder
for (Map.Entry<String, Object> s :
filtermap.entrySet()) {
query.setParameter(s.getKey(),
s.getValue());
System.out.println(s.getKey() + " " +
s.getValue());
}
for(Map.Entry<String, Date> s :
filterdatum.entrySet() ){
query.setParameter(s.getKey(), s.getValue(),
TemporalType.DATE);
}
List resultList = query.getResultList();
listeauftraege.addAll(resultList);
}
catch(IllegalArgumentException e){
e.printStackTrace();
throw new
HermesRuntimeException("AuftragsverwaltungBean/getAuftragslliste:
Auragsliste konnte nicht geladen werden, da Query ungültig");
}
return listeauftraege;
}
Yes, WAS61 with FixPack
this is the code for my update:
public void updateAuftrag(Auftrag auftrag) throws HermesRuntimeException {
// begin-user-code
try {
Auftrag a=em.merge(auftrag);
em.flush();
} catch (Exception e) {
e.printStackTrace();
throw new HermesRuntimeException(
"AuftragsverwaltungBean/updateAuftrag: Auftrag
konnte nicht aktualisiert werden");
}
// end-user-code
}
the updates, where I change the value to an other value are
successfull...,except the changes to null
