Design A Simple Service-Oriented J2EE Application Framework Reading Note:
ONE:
The service broker layer will be added between the Web tier and the business tier. Conceptually, an Action calls a business service request only, which passes the request to a service router. The service router knows how to hook up business service requests to different service provider controllers or adapters by looking up a service mapping XML file, X18p-config.xml. The service provider controller has specific knowledge of finding and invoking the underlying business services. Here, business services could be anything from POJO, LDAP (lightweight directory access protocol), EJB, JMX, COM, and Web services to COTS (commercial off the shelf) product APIs. X18p-config.xml should supply sufficient data to help the service provider controller get the job done. Leverage Spring for X18p's internal object lookup And References. Build Service Provider Controllers Incrementally. As you willtee, The More Service Provider Controllers Implement, The More Integration Power X18P Has. protec T EXISTING KNOWEDGE SUCH AS STRUTS, BUT Keep Eyes Open for New Things COMING UP Add Service Broker between Web Tier and Business Tier, allowing it to route requests to different service controllers. The interface of the Business Manager is not exposed to the action. Action only needs to pass the INPUT to the specified Service Provider, and then wait for the Output.
