Dear, I have a general question to have a "drools starter" on my project I come here to query your drools experience :-) I have a mysql data base which are my fact. I see some old drools post using spring intergration and some more recent post about camel . I do not understand, which way i should to take, to me : - camel is a server ( i do not know never used it ) - spring integration is used to connect multiple ressource I though to use : - spring as light container - hibernate 4 to query db - spring roo to do some reverse-engeneering on my db - drools a rule engine I would like the uptodate approach to perform this. The only "Must be" is "open-source project" thanks for your advice
