Jess doesn't have a regular expression matcher, although this is
something I've contemplated putting in.
You can do what you want by calling out to Java explicitly; for
instance, you could use String.indexOf():
(defrule list
(row (name ?s&:(neq -1 (call ?s indexOf "new"))) (value ?b))
=>
(printout t "List:" ?b crlf ))
I.e., we're testing the Java expression s.indexOf("new") != -1 .
