If I neglect to round my BigDecimal values to hundredths, I get an exception when trying to persist with session.save(obj). So long as I do the rounding before a save, the ArrayOutOfBoundsException goes away. The scale and precision parameters appear to have no effect.

Is there a way to take care of this via mapping or will I always need to do the rounding?

Hibernate version: 3.1.3

Dialect: org.hibernate.dialect.SQLServerDialect

Driver: com.microsoft.jdbc.sqlserver.SQLServerDriver

Mapping documents:
<property name="payment" type="big_decimal">
<column name="payment" precision="9" scale="2"/>
</property>
<property name="total" type="big_decimal">
<column name="total" precision="9" scale="2"/>
</property>

Column definitions in DB:
[payment] [numeric](9, 2) NULL ,
[total] [numeric](9, 2) NULL ,
