JBoss Drools 4.0 has just been released :) We are really proud of what we have done here. We believe that we now have the best and most powerful declarative rule language, bar none; commercial or open source. The Rule Flow is excellent and I really enjoyed updating the Conway's Game of Life to Rule Flow; sub Rule Flows and milestone support will be coming in a point release soon. The BRMS has long been requested and we put a lot of effort into the ajax based design. The Eclipse improvements for the debug points and guided editor should help reduce learning curves, opening us to new audiences. Of course performance is now much better, especially for complex rules and the new Sequential Mode should be very popular with decision services. Boss Drools 4.0 can be summarised as: * More expressiveness. * More powerful declarative keywords. * Hibernate ready, with 'from' keyword for evaluating external data. * Pluggable dialects, with new MVEL dialect. * New Rule Flow and Eclipse modeller. * Better Performance. * IDE Improvements. * Enterprise Ready with Web 2.0 Business Rules Management Studio.

CONGRATULATIONS :o) And BIG Thanks guys! Brilliant Job. Hope we can contribute better to your release. If nothing else atelast the documentation. Actually, have discovered a lot of things and notes and am wondering how to share it back. Example, writing multi table decision tables, rule sequencing without using Agenda Groups in Decision Tables etc. How can we contribute back, is this the best place to post? Not sayin its all quality, but you filter it out ;o) congrats again, Arjun _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Mark, Any idea when 4.0GA will be up on the jboss maven repo? Thanks!

Due to how JAXB treats anonymous inner complex types, I ended up with a public static inner classes named AlternativeKey in several of my data classes I have several rules written to deal with each data class individually that all work ok. However, when I attempt to put them all in the same rule base (all belong to the same package), I get an import collision exception on the AlternativeKey inner class. Depending on where in the builder I add the resource depends on which AlternativeKey the compiler bitches about (validity). I'm not familiar with the source at all, so I'm unsure as to where to look for this. However, this sounds like a bug to me? There is an easy workaround for this as I I just don't use anonymous types and define them in my schema explicitly. Just thought I'd identify this as a possible issue.
