Hi all,
I get a 'java.lang.ClassCastException: java.lang.String' when i use a
criteria with a diffenrent class-Type.
Do i have to use the same class-type as discribed in the repository-file?
-> this function works fine!
----------------------
public static Iterator getAllPrj (PersistenceBroker _broker, Integer
_iProjectFilter) {
Criteria c = new Criteria ();
c.addEqualTo ("ID_PRJ", _iProjectFilter);
QueryByCriteria qc = new QueryByCriteria (Application.class, c);
return _broker.getIteratorByQuery (qc);
}
----------------------
-> but when i take this function, i get an 'java.lang.ClassCastException:
java.lang.String' exception!
(in the OJB-Version 0.8.375 this works)
----------------------
public static Iterator getAllPrj (PersistenceBroker _broker, String
_strProjectFilter) {
Criteria c = new Criteria ();
c.addEqualTo ("ID_PRJ", _strProjectFilter);
QueryByCriteria qc = new QueryByCriteria (Application.class, c);
return _broker.getIteratorByQuery (qc);
}
public static Iterator getAllPrj (PersistenceBroker _broker, Integer
_iProjectFilter) {
return getAllPrj (_broker, _iProjectFilter.toString());
}
----------------------
I use OJB 0.9.5 with an oracle-plattform.
thanks
Gerald
