I've got a boolean field in my class and it is mapped to accessed by field (and not accessors), the proper column in Oracle is a NUMBER(1).

When fetching data from Oracle a

org.hibernate.PropertyAccessException: could not set a field value by reflection setter of com.payeshgaran.MyClass.myBooleanField
org.hibernate.PropertyAccessException: could not set a field value by reflection setter of com.payeshgaran.MyClass.myBooleanField

at org.hibernate.tuple.AbstractEntityTuplizer.setPropertyValues(AbstractEntityTuplizer.java:330)
at org.hibernate.tuple.PojoEntityTuplizer.setPropertyValues(PojoEntityTuplizer.java:191)
...

occures.
Is there any way to solve this problem?

mmm,
sorry it was just because of "@SecondaryTable" uses outer join instead of inner join ....
