Hello everybody: I am taking a look at Drools Integration documentation to understand how Drools server works and how can be used, and have a doubt concerning, let's say... 'KnowledgeAgent capabilities'. Does Drools server support on the fly rule updating as when using KnowledgeAgent to create KnowledgeBase objects? If it does, where can be configured 'KnowledgeAgent related' properties such as newInstance or resource scanner interval? Thank you in advance for your time. Kind regards, Manuel Ortiz. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Yes, your approach is also ok. I was about to create the servlet I have mentioned. Now I'm wondering which one is the best approach. About reloading rules with declared types, yes, there is a known issue. They are added multiple times in the classloader leading to ClassCastExceptions. We are working on a solution. It would be nice if you could file an issue in Jboss' jira (https://jira.jboss.org/) to keep track about the progress.
