JBoss has announced a faster version of JBoss Rules, the company’s open source business rules engine.
Gains in speed in the new release, version 4.0, have resulted in rules processing in seconds as opposed to minutes, says Burr Sutter, technical product manager for JBoss. Speed has been increased by new “sequentiality” methods, which do not assume the rules change all the time. The product is 40% faster than before.
Based on the JBoss Drools Project, JBoss Rules is used to set rules within a business process. It can be deployed for functions such as establishing computational business logic associated with an application, for example a pricing engine or a routing node.
“It allows non-programming staffers to actually interact with [JBoss] Rules and develop rules, and it gives the administrators the opportunity to have lifecycle control over those rules,” Sutter says.
The ability to express rules has been enhanced in version 4.0 through the addition of support for MVEL (MVFlex Expression Language). Support also continues for Java rules.
“We have a much more powerful language environment now,” Sutter says.
JBoss Rules is being integrated with the JBoss ESB (enterprise service bus), in which the rules engine can examine the content of a message, such as an invoice, and make decisions on where to send the message. The ESB handles message flow while Rules serves as a “traffic cop” working in conjunction with the ESB, says Sutter. JBoss provides a “rules service” for the ESB.
A guided rules editor has been added, allowing users to point and click to declare a business rule using list boxes.
JBoss Rules 4.0 is also described as being Hibernate-ready; that is, it can function with JBoss’ Hibernate object-relational mapping software.
