+ * <p>
+ * ConcreteClassConvertingRowReader overrides the extractOjbConcreteClass
method to allow OJB sqlToJava field conversion for the ojbConcreteClass field
+ * with OJB 1.0.3 (OJB 1.0.4 has this fixed).

+ * </>
+ * <p>
+ * This extension allows to store the objConcreteClass field as needed for
Polymorphism support in OJB differently,
+ * e.g. not as its className but allow lookup of if based on a different
value, e.g. like "user" -> org.apache.jetspeed.security.JetspeedUserImpl
