I send you the transactioon code:
db=this.getConnection();
db.begin();
oql=db.getOQLQuery("select a from
domain.metaSystem.style.PLColor a ");
results=oql.execute();
Object o;
while(results.hasMoreElements())
{
o=((Object)results.next());
v.add(o);
}
db.commit();
return v;
Tanks for your help,
Fabio
