Section 7.4.3 explains validating input. What about validating numeric input that is
stored as a BigDecimal?

For example:

@Column(name = "COST_DOLLARS", precision = 11, nullable = false)
private BigDecimal costDollars;

How would you validate this in Spring? Since data binding happens before validation,
if the user enters "A" instead of 100.00 in the costDollars field on a jsp form, how
do you validate costDollars? Does @Valid and JSR-303 work for numeric data? Or does it just work for character data? I would like to avoid storing costDollars in a character variable and then having to convert it to a numeric variable. I was finding that JSR-303 works fine for character validation but seems to not work for variables, such as costDollars.

Thanks for any advice on this.
