اسلاید 9: 9Master of Information System ManagementReference Architecture Middleware View (1)Business Application Services are at the core (fundamental & repeatable business tasks & identified by SOMA)Tool support for this layer: WebSphere app server JBOSS, Glassfish, etc…

اسلاید 10: 10Master of Information System ManagementReference Architecture Middleware View (2)Access Services Layer Dedicated to integrating existing applications and functions into an SOA.Tool Support of this layer: WebSphere Adapters BEA adapters Sun SeeBeyond Adapters,…Adapters implemented with J2EE Connector Architecture (JCA)

اسلاید 11: 11Master of Information System ManagementSome Notes on JCAAn EIS includes ERP systems, legacy systems, mainframe database and transaction processing systems.A resource adapter is written for the EIS.The adapter must communicate with the container and clients.JCA defines system contracts between the application server and resource adapters.JCA defines the client API of the resource adapter.A resource adapter is analogous to a JDBC driver.

اسلاید 12: 12Master of Information System ManagementReference Architecture Middleware View (3)Partner Services Layer Can be viewed as a special case of interaction services - representing the integration of external entitiesGovernment servicesOther higher education services, etc.

اسلاید 13: 13Master of Information System ManagementReference Architecture Middleware View (4)Interaction Services Layer - Captures the logic of presentation to the entities external to CMU - Web Frameworks, e.g., struts, JSF, Ruby on Rails, provide a configurable sequence flowTool Support for this layer: IBM WebSphere Portal Server JBOSS Portal Vignette (industry leading implementation of JSR-168 Web Services for Remote Portlet WSRP) Apache JetSpeed, JSF, Spring Framework, etc…

اسلاید 14: 14Master of Information System ManagementReference Architecture Middleware View (5)Process Services Layer Captures process flows and business rules.Tool Support: - IBM WebSphere Process Server (SCA and BPEL) - Apache Tuscany (SCA, SDO and BPEL) - Active BPEL - Glassfish - Oracle Business Rules using RETE rules engine - IBM bought ILOG and now has a rules engine - Redhat DROOLS
