I need some advice on the best approach to solving this problem.

I've researched DROOLS, Java Rule Engine and a few others. All of these are powerful, and have good things about them. I don't know which (if any) will be the best choice for me.

I have one business object. (simplified for demo)

Person
     firstName:String
     lastName:String
     departMent:String
     hireDate:Date

I need to write an editor in a web application that will allow for complex rules to be built around these fields. I need to support complex nested AND/OR logic. I just need basic operators, and the rule should simply evaluate to true or false. If the rule evaluates to true or false, one action will occur respectively.

For example,

firstName CONTAINS "value" AND (lastName РАВНО "вход" ИЛИ отдел CONTAINS "input")

I had thought, maybe I should just write my own parser and evaluate the logic in my own code. I don't know what to do, any advice or links to something to read would be greatly appreciated. Is there a specific design pattern I could research?

How would you solve this problem? One reservations about the rules engines is that maybe they are too complex for just a simple problem?
