i copy the following from the Documentation. i thought it means that drools is going to auto convert the string "27-Oct-2007" into a java Date object.

Date

The date format "dd-mmm-yyyy" is supported by default. You can customize this by providing an alternative date format mask as a System property ("drools.dateformat" is the name of the property). If more control is required, use the inline-eval constraint.

Example 6.20. Date Literal Restriction

Cheese( bestBefore < "27-Oct-2007" )
