Re: [rules-users] Dynamic Loading of Rules from BRMS

Hi, Thanks for the quick response. Can I just point the URL to my package in the jboss-brms which I need to access instead of specifying each rule? And if I end up adding a new rule at runtime without modifying an existing rule it should also be detected right? thank you.
