Knowledge is everything
Tom Baeyens has a good post on the jBPM (JBoss workflow) community day that was held at the Guinness brewery in Dublin. As you’d expect, the slides have plenty of pictures of people drinking beer, and one or two pictures of people talking about workflow and business processes. (Do not adjust your TV set.

Paul Haley, founder and chairman of haley.com, has just written a very in depth blog covering rules and processes and when to use which and the various ways they overlap. It’s pretty much a “must read” for people trying to understand this space; heh, and he mentions our work in this efforts at the endRead more →
Many of you would have read my blog on unifying rules and processes, which was also featured at infoq. Unifying these technologies is not just about the modelling paradigm it’s also about the infrastructure overlaps. Today I just finished my first end to end test for dialectable actions in a processes definition – which weRead more →
Since Drools 4.0 I’ve been demonstrating our ruleflow stuff, which includes a graphical designer and basic rules and process integration for stateful rule orchestration. What is ruleflow? Ruleflow is the integration of rules and processes, which can predominantly be used to orchestrate the execution of rules. Additionally what 4.0 also provides is a prototype toRead more →
Diego Adrian Naya Lazo has just published an OSWorkflowBook “OSWorkflow: A guide for Java developers and architects to integrating open-source Business Process Management”. I’ve no idea if the book is any good or not but it has a whole chapter on Drools integration:Chapter 5 introduces and integrates Rules engine and Drools open source rule engine.Read more →
Drools 4.0.1 will include SubFlow and Milestone support, below shows a screenshot of the new pallet. For more information on WorkFlow patterns see http://workflowpatterns.com. Drools 4.0.1 will also include a new Number Guess example that shows a recursive rule flow. Here you can see the Rule Flow branch constraint editor with context assist. As mentionedRead more →
As promised I finally got round to updating the popular Conways Game of Life example so it can be executed with both agenda-groups and ruleflows for execution control. So now people have a good example to study when trying to learn the two concepts. (click to enlarge images). With agenda-groups we specify the stack executionRead more →
Code completion has just been added to the constraint editor for ruleflow ‘splits’ and ‘joins. ‘and’, ‘or and ‘xor’ type logic can be applied and the constraint used for each branch. The same constraint language is used as the left hand side (LHS) ‘when’ part of a rule, and that constraint monitors the Working Memory.Read more →
Kris has worked his magic again and it’s now possible to make decisions on ‘split’ and ‘join’ nodes in Rule Flow. ‘split’ nodes now support ‘and’, ‘or’ and ‘xor’ type decisions while ‘join’ supports ‘and’ and ‘or’. The beautiful part of this is its fully tooled and the decisions are specialised rules, so you canRead more →
A new feature has been added to the JBoss Rules code, allowing users to create a graphical flow chart that defines the order in which rule sets should be evaluated. This blog shows some examples on how to use ruleflow. Ruleflow will be available in the next milestone release, and really anxious users can alreadyRead more →
