Re: [rules-users] Drools with Guvnor

With the new KnowledgeAgent API, you can not only connect to Guvnor server remotely to store and retrieve rules, but also to add or update rules. It also has basic authentication supported. Take a look at the unit test: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-compiler/s

Yes and no . Guvnor uses a JCR repository (the default is http://jackrabbit.apache.org/) which can not be accessed using hibernate directly. We ran into this issue, and the only way to use guvnor as of 6 months ago was to have a user go into guvnor and create a DRL file by clicking a few button
