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

[Jaroslaw Kijanowski]

Yeah, but that's not a drools issue any more. I guess your regexp is not 
sufficient to catch an email address.
The rule will fire when you provide @aa but it will not fire if you use 
@aa.com, right? google for "Validate an Email Address" and you will find 
regexps which will handle the "dot" and other chars.

Cheers,
