[rules-users] Expert versus Expert

Hi all, i'm a newbie on Drools and want to understand the general architecture of the solution. Is it true that Drools Guvnor helps managing rules definition but it is not a rule server ? Meaning we can define, update, archive, test... rules but not execute them in Guvnor? My understanding is that Drools expert is the engine, let's say the rules server) on which one rules are executed. Is there any graphical tool to manage this engine? I mean to add/remove rules, access a dashboard... Is it drools-server.war? Is there any pre installed runtime environment with the engine and - if there is one - the management console? I tried drools-install.zip with ant install.demo but it doesn't work for me... Thanks a lot for your feedback, I'm waiting to test it! Charles Souillard
