17. Partner Partner Service-Oriented Architecture (SOA) What is SOA? • SOA enables flexible connectivity of applications or resources by • Representing every application or resource as a service with a standard interface • Enabling them to exchange structured information Why do you care? • SOA helps introduce flexibility in a technology environment. There is growing acceptance of SOA as an approach to integration and to structure collections of interacting applications. Horizontal Process Integration Business Flexibility Infrastructure Management IT Simplification The flexibility to treat business processes and the underlying infrastructure as defined components that can be mixed and matched at will

34. J2EE Architecture

35. J2EE Highlights: 1. EJB • EJB is a server component architecture to develop distributed, transactional, secure and portable Java applications. Three types of EJBs: • Entity Beans – Each entity bean object represents a unique row in its related table. For example: Student is an entity bean in a grading system application. • Session Beans – Session beans use entity beans to perform transactions. For example: AssignGradesToStudent session bean • MDB (Message driven beans) – MDBs support EJB integration with outside enterprise applications.

36. J2EE Highlights: 2. Servlets/JSPs • Java servlets allow a mechanism to extend the Web server functionality: • Servlet’s entry point is its service() method • service() method accepts two arguments – HTTP request and HTTP response. • HTTP request – is the request from the web browser • HTTP response – is the servlet’s response to the browser • JSP simplifies creating dynamic HTML pages by allowing developers to embed Java code inside an HTML document.

37. What Is Struts? • Struts is an Apache’s open source MVC (Model-View-Controller) framework. • Struts consists of a primary Servlets controller class called ActionServlet. This controller servlet is the primary recipient of all HTTP requests. • Struts provides the concept of Action classes: customized classes that can be developed to handle different types of requests and render appropriate HTML or JSP pages.
