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

[Jaroslaw Kijanowski]

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.

Cheers,
  Jarek
