Drools 2.0, an open source business rules engine, is now available via BSD licensing. The declarative rules engine can be used in applications for setting of conditions for transactions, according to Bob McWhirter, founder of Codehaus and the originator of Drools. Codehaus is hosting Drools 2.0.“With Drools, you can describe what needs to happen when certain conditions are met,” McWhirter said. He cited as an example an insurance application that gives discounts to customers based on conditions such as age or marital status. Drools uses the Rete algorithm. Version 2.0 is the first production-ready release of Drools. Software Development
