I do have same kind of problem here. The User should be able to enter and also edit rules. Is there any kind of GUI available for JBOSS Rules? What solution you came up with? Please do respond.
There is a user supported mailing list for JBoss rules where you can get answers.
Also, currently you can use excel to manage rules, and the Eclipse IDE for a developer friendly GUI.
However, in the nest major version there are tools and web based user interfaces and more coming.
