Date Thu, 22 Jul 2004 12:50:17 GMT
Would you happen to have an example of this so I can look at it since
I'm new to the commons api?

No, validator does not support pulling min/max values from an object. 
the nice thing about commons-validator is that it doesn't take much
to write your own reusable validation action that supports your custom
cases.  Basically, you just write a validation method that uses
and <var-value> values to get the bean's method name to call and
your validation method in validation.xml as a <validator>.
