First Look – Drools 5.0

5.0 adds a web-based decision table editor as well as a web-based ruleflow viewer that uses GWT Diagrams to show flows (they plan web-based editing of flows in the future, but for now the editing of the flows must be done in Eclipse. The ruleflow editor has been upgraded pretty significantly too into much more of a real decision flow editor or even a workflow editor. The editor is slick and has a nice pallette of features. Splits, joins, for each, subflows, human tasks, timers and an interface allowing you to add you own kinds of nodes make the flow much more extensive than before. DSLs (of which more in a second) can be built allowing DSL nodes to be created in the flow to make it very business user friendly. There are a few oddities around defining the rules for a node and navigating from the ruleflow to the rules but overall I really liked what they have done.
