[rules-issues] Working with regular expressions with JBOSS rules

Dear Sir, I'm trying to use a regular expression with drools but unfortunately it doesn't seem to work. I've read a lot on the mailing list but i have not found a solution yet. Keep in mind that Drools is totally new to me (i have read most of the manual) and some things are still a bit bizarre to me. * rule* "name check" *when * $form : PersonForm(firstName *matches* "[a-zA-Z]*" ); *then * $form.setChecked(*true*); *update*($form); * end I have tested my regular expression in a simple java application and this works. I do not get a error message, but my cpu peaks to 100% and my memory mounts until 200+ mb. And this does not change until i reboot the server. (JBOSS 4.0.5). Thanks in advance, Jonathan. *
