J2EE Application Architect Training

Application Design Concepts and Principles

•   Explain the main advantages of an object-oriented approach to system design including the effect of encapsulation, inheritance, and use of interfaces on architectural characteristics.
• Describe how the principle of "separation of concerns" has been applied to the main system tiers of a Java Platform, Enterprise Edition application. Tiers include client (both GUI and web), web (web container), business (EJB container), integration, and resource tiers.
• Describe how the principle of "separation of concerns" has been applied to the layers of a Java EE application. Layers include application, virtual platform (component APIs), application infrastructure (containers), enterprise services (operating system and virtualization), compute and storage, and the networking infrastructure layers.

Common Architectures

•    Explain the advantages and disadvantages of two-tier architectures when examined under the following topics: scalability, maintainability, reliability, availability, extensibility, performance, manageability, and security.
•     Explain the advantages and disadvantages of three-tier architectures when examined under the following topics: scalability, maintainability, reliability, availability, extensibility, performance, manageability, and security
•      Explain the advantages and disadvantages of multi-tier architectures when examined under the following topics: scalability, maintainability, reliability, availability, extensibility, performance, manageability, and security.
•      Explain the benefits and drawbacks of rich clients and browser-based clients as deployed in a typical Java EE application.
•      Explain appropriate and inappropriate uses for web services in the Java EE platform

 Integration and Messaging

·      

•         Explain possible approaches for communicating with an external system from a Java EE technology-based system given an outline description of those systems and outline the benefits and drawbacks of each approach.
•         Explain typical uses of web services and XML over HTTP as mechanisms to integrate distinct software components.
•          Explain how JCA and JMS are used to integrate distinct software components as part of an overall Java EE application.

      Business Tier Technologies

•          Explain and contrast uses for entity beans, entity classes, stateful and stateless session beans, and message-driven beans, and understand the advantages and disadvantages of each type.
•          Explain and contrast the following persistence strategies: container-managed persistence (CMP) BMP, JDO, JPA, ORM and using DAOs (Data Access Objects) and direct JDBC technology-based persistence under the following headings: ease of development, performance, scalability, extensibility, and security.
•          Explain how Java EE supports the deployment of server-side components implemented as web services and the advantages and disadvantages of adopting such an approach.

Web Tier Technologies

•  State the benefits and drawbacks of adopting a web framework in designing a Java EE application
•  Explain standard uses for JSP pages and servlets in a typical Java EE application.
•  Explain standard uses for JavaServer Faces components in a typical Java EE application.
•  Given a system requirements definition, explain and justify your rationale for choosing a web-centric or EJB-centric implementation to solve the requirements. 

Section 6: Applicability of Java EE Technology

•         Given a specified business problem, design a modular solution that solves the problem using Java EE.
•          Explain how the Java EE platform enables service oriented architecture (SOA) -based applications.
•          Explain how you would design a Java EE application to repeatedly measure critical non-functional requirements and outline a standard process with specific strategies to refractor that application to improve on the results of the measurements for Enterprise Applications with Java EE Content Details
