9 95-843: Service Oriented Architecture Material taken from IBM CMU Ref. Architecture Document 9 Master of Information System Management Reference 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…

10 95-843: Service Oriented Architecture Material taken from IBM CMU Ref. Architecture Document 10 Master of Information System Management Reference 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)

11 95-843: Service Oriented Architecture Material taken from IBM CMU Ref. Architecture Document 11 Master of Information System Management Some Notes on JCA An 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.

12 95-843: Service Oriented Architecture Material taken from IBM CMU Ref. Architecture Document 12 Master of Information System Management Reference Architecture Middleware View (3) Partner Services Layer Can be viewed as a special case of interaction services - representing the integration of external entities Government services Other higher education services, etc.

13 95-843: Service Oriented Architecture Material taken from IBM CMU Ref. Architecture Document 13 Master of Information System Management Reference 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 flow Tool 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…

14 95-843: Service Oriented Architecture Material taken from IBM CMU Ref.
