Most often after deploying new business rules in BRES, we have to redeploy IlrSession beans with our custom beans(XOM). Also developing new client for the business rules is time consuming work. Bres(Business rules execution server) provide rmi protocol and some web service support(Decision service) to invoke rules in bres. Deployed rules will be exposed only when you add your domain class(XOM) in the jrules-bres-ootbds.ear and redeploy it again in application server. All the life cycle is too time consuming to manage the whole project. However, often business analyst (Most of time, project mangers require such thing to fulfill customers demand) requires expose business rules through web service for solving business requirement with customer. In today's post i will show a agile way to expose business rules through web service and run it into jdk 6 embedded http server. We have one web service with a few methods, every method expose one business rules as a web method. For developing...

Apache tucsany provides a framework for developing SOA solution that is based on Service Component Architecture (SCA) standard. Tucsany offers following advantages: 1) Provides a model for creating composite applications by defining the services in the fabric and their relationships with one another. 2) Enables service developers to create reusable services that only contain business logic. 3) Existing applications can work with new SCA compositions. This allows for incremental growth towards a more flexible architecture, outsourcing or providing services to others. Tucsany implemented in java and c++ programming language. For more information visit apache tucsany site . In the growing uses of business rules in SOA, on the current post i decide to make a laboratory work to show how to use business rules in SCA SOA solution. For more information to get benifit from business rules please consider my some previous post about Ilog business rules. On the current tutorial we are goin...

Ilog Jrules define decision service as a ordinary web service with management capabilities using JMX MBeans. Through protocol SOAP, it's easy to invoke business rules rather than any other protocol like rmi. More information about decision services should find here. From the view of ilog jrules, there are two types of decision services: 1) Hosted transparent decision services 2) Monitored transparent decision services All of them drives rule execution and enables users to access Rule Execution Server through a Web service, rather than accessing it directly. Hosted transparent decision services: Using a hosted transparent decision service, Rule Execution Server automatically exposes any deployed rule set as web services, that uses an XML schema or a Java XOM with simple types. The decision service automatically generates Web Services Description Language (WSDL) file for each deployed ruleset archive and the decision service MBean is able to retrieve execution statistics. These rule...
