Re: [rules-users] how to write regular expressions in drools..

Hi, you have to escape characters with regexp meaning (see docs for details). Try this: email matches "@\[A-Za-z0-9\]*" phone not matches "\\\\d{3}\\\\-\\\\d{3}\\\\-\\\\d{4}" Moreover I guess your rule is anyway broken, you will get a cross product of Orders, so I would remove "There is an Order" from both rules.
