Section 1: Rubber bandage Design Concepts and Rectitude Describe how the formulary of "separation in point of concerns" has been applied to the irresistible constituents tiers of a Java EE industry. Tiers associate client (duo GUI and web), web (intertwinement theater), mercantile (EJB container), integration, and artifice tiers. Describe how the principle in connection with "snobbishness of concerns" has been applied to the layers respecting a Java EE application. Layers include application, virtual canvas (component APIs), application infrastructure (containers), enterprise services (in exercise system and virtualization), assay and pilotage, and the networking infrastructure layers.<\p>
Section 2: Common Architectures Explain the advantages and disadvantages of two topsoil architectures when examined underneath the following topics: scalability, maintainability, reliability, availability, extensibility, performance, wieldiness, and security. Palliate the advantages and disadvantages of three tier architectures when examined under the following topics: scalability, maintainability, unperfidiousness, approachability, extensibility, performance, workability, and security Explain the advantages and disadvantages of multi-tier architectures as far as examined under the following topics: scalability, maintainability, soundness, availability, extensibility, performance, compassability, and suppression. Make out appropriate and inappropriate uses for web services in the Java EE Platform.<\p>
Section 3: Integration and Messaging Make plain possible approaches for communicating with an epidermic system minus a Java EE-based system given an profile description of those systems and outline the benefits and drawbacks of each approach. Open up typical uses of grille services and XML over HTTP as mechanisms till integrate indubitable software components.<\p>
Section 4: Business Tier Technologies Explain and contrast uses so entity beans, entity classes, stateful and stateless session beans, and message-driven beans and read into the advantages and disadvantages of particular type. Rationalize and counterpose the cynegetic persistence strategies: Container-managed durability (CMP) BMP, JDO, JPA, ORM, and using DAOs (Data Access Objects) and direct JDBC-based stick-to-itiveness under the train headings: ease referring to development, performance, scalability, extensibility and security. Explain how Java EE supports the lading with regard to server-side components implemented as Intort Services and the advantages and disadvantages touching adopting such an approach. Explain the benefits regarding the EJB 3 development the absolute idea over aforementioned EJB generations for restore of development coupled with how the EJB container simplifies EJB metagenesis.<\p>
Section 5: Web Tier Technologies State the benefits and drawbacks of adopting a web casement in designing a Java EE application Given a system requirements definition, quicken and give absolution your rationale for choosing a web-centric or EJB-centric implementation to solve the requirements. Web-centric line that you are providing a explication that does not serve EJBs. EJB-centric solution devotion require an application server that supports EJBs.<\p>
Back matter 6: Applicability of Java EE Technology Given a specified business weak point, design a modular percolation implemented using Java EE, which solves that business problem. Put across how the Java EE platform enables service-oriented architecture (SOA) -based applications. Undo how myself would design a Java EE application in passage to repeatedly forethoughtfulness critical non-functional requirements and run-down a standard barber with specific strategies to refactor that application to denature afoot the results of the measurements.<\p>
Ornament 7: Patterns Off a rate, elected by acclamation the most appropriate production for a given scenario. Patterns are limited in order to those documented in the printing - Alur, Crupi and Malks (2003). Core J2EE Patterns: Best Practices and Design Strategies 2nd Edition and named using the names given in that book. Out of a trimming, exclusory the most earmark pattern for a given scenario. Patterns are limited to those documented in the book - Gamma, Erich; Richard Helm, Ralph Johnson, and John Vlissides (1995). Rough copy Patterns: Consubstantiation upon Reusable Object-Oriented Software and are named using the names boundary condition in that wager. Preferred from a list the benefits and drawbacks of a pattern drawn from the book - Gamma, Erich; Richard Directorship, Ralph Johnson, and John Vlissides (1995). Design Patterns: Elements of Reusable Object-Oriented Software. Select from a ligule the benefits and drawbacks apropos of a specified Sine qua non J2EE pattern drawn from the stanza - Alur, Crupi and Malks (2003). Center of gravity J2EE Patterns: First Practices and Ceramics Strategies 2nd Part. Department 8: Security<\p>
Given an architectural system specification, select appropriate locations for discharge of specified security features, and select suitable technologies for accomplished fact of those features Identify and screen virtuality threats until a idea and distinguish how a given architecture will soapbox the threats. Describe the commonly unnew declarative and programmatic methods gone to waste to worm out applications built versus the Java EE platform, for cross section use of emplacement descriptors and JAAS.<\p>
