Re: [rules-users] Embedded Drools into clustered application
You get the idea! Now you are available to run on Local and Remote (using mina, I hope in less than a month we support hornetQ as well) and also DIstributed nodes (Rio). Allowing you to start using Local for your testing and initial development (following some of my rules about remote/distributed environments, I will post some about this today or tomorrow on my blog) and then move the Remote or Distributed. Greetings! :) On Mon, Aug 16, 2010 at 11:36 PM, Tan Hui Onn hui...@gmail.com wrote: Thanks for your reply.
