Re: [rules-users] Drools Flow Persistence Doubt

Hi Mauricio, Thanks for your reply.

Am i doing something wrong? Thanks & Regards Pardeep Ruhil if you take a look at this post: http://blog.athico.com/2009/09/drools-flow-variable-persistence.html you will see that there is a demo project with the configuration to work with MySQL.
