[rules-users] Design Pattern for Business Workflow

Hello everyone, I'm new to Drools and Rules engine in general. My request is probably recurrent (i tried many search on Google and forums). I'm trying to find a good design pattern for Rule based workflow. What I'm doing is a WebApplication (GWT) with a Business Tier and the rules would be used for booth presentation and business. Question : can someone give my a tips, links, or anything else to help me design such a Rule based application (mainly the design of the interface). Thanks. -- Best regards, Sebastien Degardin Skype sebastiendeg <a href=" http://javaone2007.leveragesoftware.com/profile_view.aspx?customerid=sdeg... src=" http://javaone2007.leveragesoftware.com/businesscard.aspx?customerid=sdeg... border="0" alt="Join Me at the 2007 JavaOne Conference Event Connect Tool!"></a>
