This two-day, intermediate course focuses on some advanced issues in developing EJB 2.0 based applications using WebSphere Studio Application Developer (WSAD) and WebSphere Application Server (WAS). In this course you examine, in detail, some of the services provided by the EJB framework such as Transactions, and Security. This course also covers the issues in building advanced, web-based clients for EJB servers using the Java Servlet and Java ServerPages (JSP) technologies, and integrating them with the EJB server applications to provide thin, HTTP and HTML browser-based clients. The primary focus of this course is on the following topics:

• Transactions - The EJB standard specifies a number of transactional attributes that may used to configure the Enterprise JavaBeans. The EJB developer may elect to implement the functionality to manage the transactions explicitly, or the transactions may be managed automatically by the EJB Container. You shall explore all possible transactional attributes specified by the EJB standard and understand the design and performance issues in implementing transactional beans. You shall build transactional Entity and Session beans, manage the propagation of the transactional context across beans and method calls and also study the implications of explicit transaction management from a client, using the Java Transaction API (JTA). You shall also implement transactional Stateful Session Beans using the SessionSynchronization interface. You will also understand the implications of exceptions during transaction processing.
• Security - The EJB standard enables the declarative specification of the security policy. The security policy enables the application administrator to authenticate remote clients that seek to access enterprise beans and to control access to these beans, applications and other resources in a flexible, intuitive and declarative fashion. The security policy is specified in terms of security roles and privileges. You shall also study the issues in integrating legacy security infrastructures, such as LDAP authentication servers and Windows NT Account Manager, with the EJB application server. You shall also study the propagation of the security context across beans and method calls.
• Java Servlets - Java Servlets technology helps extend the functionality of the EJB server hosting the business applications. Servlets also enable the enterprise developers to build component-based, server-side clients that generate and serve Web pages dynamically. In this course, you shall examine the design and implementation issues of integrating Servlets with EJB-based server applications. You shall also study the architectural benefits of implementing client applications using the Java Servlet technology. Other issues covered here include session management, authentication, servlet chaining and dynamic content generation based on the EJB business logic implementation.
• Java Server Pages (JSP) - The JSP technology enables the designer of Web pages to include Java programs and inter-mix them with normal HTML. Using JSP, developers can access other Java applications and business objects within HTML. The JSP technology, like Servlets, also enables the dynamic creation of Web pages. Using JSP, the client developers focuses on the presentation logic, usually implemented in HTML and JavaScript, and invokes Java code that is interspersed within HTML code. You will also study the design techniques of wrapping JavaBeans^TM around Enterprise JavaBeans and embedding such JavaBeans in JSP Pages. You shall also integrate HTML forms with JavaBeans^TM and attach the form fields to the property fields of the JavaBeans^TM.

This course has been specially designed for professionals looking to build web-based, transactional and secure E-Business applications using the Enterprise JavaBeans technology using IBM's WebSphere Server - Advanced Edition and WebSphere Studio Application Developer (WSAD).

This course aims to teach a set of advanced skills necessary to implement transactional, secure, robust, scalable and reusable EJB-based E-Business applications. The course also aims to teach advanced Web-based client development to dynamically manage and create presentation for the HTTP clients using the Java Servlet and Java ServerPages (JSP) technology. All the development will be done using WebSphere Server - Advanced Edition and WebSphere Studio Application Developer (WSAD). This course also provides a comprehensive coverage of issues in the design and development of server-side components for managing the presentation logic. On completion, attendees will:

• Be able to develop highly transactional Enterprise JavaBeans (EJB) and clients
• Be able to develop highly secure EJB-based E-Business applications
• Be able to design and efficiently develop EJB components using WebSphere Studio Application Developer (WSAD)
• Be able to deploy EJB-based applications on IBM's WebSphere Server - Advanced Edition
• Have mastered the Java Transactions API (JTA)
• Have mastered the Java Transaction Services (JTS)
• Have mastered the Security services provided by the EJB specification
• Be able to build dynamic, Web-based, clients for the EJB servers using the Java Servlet technology.
• Be able to build dynamic, Web-based, clients for the EJB servers using the Java ServerPages (JSP) technology.
• Be able to wrap JavaBeans^TM around EJB components
• Be able to integrate JavaBeans^TM in JSP Pages
• Be able to use the Model-View-Controller design pattern to implement multi-tiered, EJB-based E-Business applications
