I would like to point out (as I experiment w/the AlphaPad Android 4 Tablet -&gt; wholesale from China) that the 'new' up and coming Android tablets really 'do' have plenty of processing power and capacity to handle the Rete Algorithm. I have ported Prolog to the Android platform (B&amp;N Color Nook) and as long as it's loaded 'properly' it runs plenty fast. I also suspect that the corporate market would have some hidden (but quite profitable) uses for Drools on the Android Tablet Platform, as I think the flood of Cheap high quality Tablets that I think China will flood the US market with, is inevitable. I live in the Netherlands (X-Pat from Chicago), so we get to see some of these trends before they hit the mainland. Just food for thought, and congrats on a great product! :-) -matt **************** On Mon, May 14, 2012 at 10:24 PM, Mark Proctor &lt;mpro</pre> Matthew Versaggi 2012-05-16T08:14:19 http://permalink.gmane.org/gmane.comp.java.drools.devel/5707 <pre>Thanks Mark...I post my question to rules-users&lt; at &gt;lists.jboss.org .... thanks again...

Since yesterday only I started learning Drools with the help of Google and *JBOSS DROOLS BUSINESS RULES pdf file*. I faced many problems to understand the concept but now its going smooth. But the problem is the *version of PDF file of the book* and the *Govener version*. *Its quite different*. I request you all to please provide me the latest version of PDF as I am unable to find on net. The problem I am facing is to put the formula as given in the screen shot in the book. I am unable to put the *formula* as described in JBOSS DROOLS BUSINESS RULES pdf file on page no. 102.....the formula is *salesValue-10 as the box is not capable of taking cahracters. *It is taking only integer.

I think it may run already if you use pure MVEL with 5.4 - or atleast a few tweaks and it shoud run. 1) probably stop the JIT kicking in to ASM bytecode statements. 2) I think I remember some classloader problem, android needs parent classloader. The other option is we pre-generate all our generated bytecode and put it in a jar so it can be resolved when needed. I've not prioritised it, because our Rete algorithm can be too eager for mobile enviornments. However I almost have lazy rete working, that merges the benefits of Rete and Leaps; the resulting algorithm is ideal for mobile enviornments. Once I get that working, I'll be more keen to accelerate our mobile efforts.

We provide both static factories and a service registry, and we ideally should continue to support both. i.e. we have KnowledgeBuilderFactory (static method factory, actually wraps below) KnowledgeBuilderFactoryService (singleton service) static example: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder() singleton service exmaple: KnowledgeBuilderFactoryService kbuilderfs = ServiceRegistry.getInstance().get( KnowledgeBuilderFactoryService.class ) KnowledgeBuilder kbuilder = kbuilderfs .newKnowledgeBuilder() All of our factory services should be registered in org.drools.util.ServiceRegistryImpl, this has delegation to say OSGi if it exists (via the service locator pattern). So we become much more friendly to OSGi or other container environments that are service locator oriented.

Below are some of the idea's on how to do that. All of these are ideas are still very volatile. Feed-back is welcome, especially if you don't like a particular naming or semantic. Global design objectives: - 1) Make selectors and generic MoveFactories faster, scalable and use less memory: by optionally not generating all the moves - 2) Make selectors and generic MoveFactories more configurable: filter on entities, variables, moveFilter, ... - 3) Unify entity, variable and value selectors under the same system, to also make them faster, scalable, memory-efficient and more configurable Let's focus on 1) MoveSelector only for now, on terminology and semantics. What does a MoveSelector need to have? Terminology of methods/attributes on MoveSelector. How would you name them? * Iterator&lt;Move&gt; moveIterator: o iterates over all the moves in the selector, based on the configuration of the MoveSe</pre> Geoffrey De Smet 2012-05-07T07:12:26 http://permalink.gmane.org/gmane.comp.java.drools.devel/5690 <pre>http://blog.athico.com/2012/04/drools-drop-in-centre-at-jboss-world.html ------ Now you have another reason to come to JBoss World &lt;http://www.redhat.com/summit/&gt;, as if you didn't already have too many on your list :) On Friday the 29th of June we'll have an all day drop in centre for Drools &amp; jBPM.

The Wumpus World example I made was well received and the 20 minute YouTube video very populate, http://www.youtube.com/watch?v=4CvjKqUOEzM. However I've since been asked for something a little simpler and smaller for a getting started example, so I thought I'd do Pong. The initial cut was done with a single commit, so it's easy to see all the code in one place: https://github.com/droolsjbpm/drools/commit/2a8746a905efe1d9e0cc9f00eae06a50b76b214b I'll follow up with a video soon, showing how it was made. &lt;http://2.bp.blogspot.com/-Ug-XbdIXMcg/T5UDDnE-iUI/AAAAAAAAAsE/rBqQcKWruhA/s1600/pong.png&gt; _______________________________________________ rules-dev mailing list rules-dev&lt; at &gt;lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev </pre> Mark Proctor 2012-04-23T07:27:12 http://permalink.gmane.org/gmane.comp.java.drools.devel/5688 <pre> I suppose this should read "...the timer is started." More precisely: "...the timer for the &lt;initial delay&gt; is started. Here I propose this amendment: If the &lt;initial delay&gt; is 0, the RHS is executed right away, and the timer for &lt;repeat interval&gt; is started, if defined. (Thus, a rule with "timer(int: 0s)" behaves like a rule without.) Every effort is made to avoid drift, i.e., the timer for another &lt;repeat interval&gt; is restarted right away, before adding the rule to the agenda. Agreed. Also, once set up and repeatedly firing, a rule with a timer is typically intended to stick to its &lt;repeat interval&gt;. All the cases I've seen (and I've seen a lot over the last 25 years) do not fiddle with this interval. If a periodic task needs to be changed, it isn't just the &lt;repeat interval&gt; but also the action, which (with Drools) would mean another rule altogether. -W _______________________________________________ rules-dev mailing list rules-dev&lt; at &gt;lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-d</pre> Wolfgang Laun 2012-04-18T06:30:40 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.comp.java.drools.devel
