Objectives:
Section 1: Concepts
- Draw UML Diagrams
- Interpret UML diagrams.
- State the effect of encapsulation, inheritance, and use of interfaces on architectural characteristics.
Section 2: Common Architectures
- Recognize the effect on each of the following characteristics of two tier, three tier and multi-tier architectures: scalability maintainability, reliability, availability, extensibility, performance, manageability, and security.
- Recognize the effect of each of the following characteristics on J2EE technology: scalability maintainability, reliability, availability, extensibility, performance, manageability, and security.
- Given an architecture described in terms of network layout, list benefits and potential weaknesses associated with it.
Section 3: Legacy Connectivity
- Distinguish appropriate from inappropriate techniques for providing access to a legacy system from Java code given an outline description of that legacy system
Section 4: Enterprise JavaBeans Technology
- List the required classes/interfaces that must be provided for an EJB technology.
- Distinguish stateful and stateless Session beans.
- Distinguish Session and Entity beans.
- Recognize appropriate uses for Entity, Stateful Session, and Stateless Session beans.
- State benefits and costs of Container Managed Persistence.
- State the transactional behavior in a given scenario for an enterprise bean method with a specified transactional deployment descriptor.
- Given a requirement specification detailing security and flexibility needs, identify architectures that would fulfill those requirements.
- Identify costs and benefits of using an intermediate data-access object between an entity bean and the data resource.
Section 5: Enterprise JavaBeans Container Model
- State the benefits of bean pooling in an EJB container.
- State the benefits of Passivation in an EJB container.
- State the benefit of monitoring of resources in an EJB container.
- Explain how the EJB container does lifecycle management and has the capability to increase scalability.
Section 6: Protocols
- Given a scenario description, distinguish appropriate from inappropriate protocols to implement that scenario.
- Identify a protocol, given a list of some of its features, where the protocol is one of the following: HTTP, HTTPS, IIOP, JRMP.
- Select from a list, common firewall features that might interfere with the normal operation of a given protocol.
Section 7: Applicability of J2EE Technology
- Select from a list those application aspects that are suited to implementation using J2EE.
- Select from a list those application aspects that are suited to implementation using EJB.
- Identify suitable J2EE technologies for the implementation of specified application aspects.
Section 8: Design Patterns
- From a list, select the most appropriate design pattern for a given scenario. Patterns will be limited to those documented in Gamma et al. and named using the names given in that book.
- State the benefits of using design patterns.
- State the name of a design pattern (for example, Gamma) given the UML diagram and/or a brief description of the pattern's functionality.
- Select from a list benefits of a specified design pattern (for example, Gamma).
- Identify the design pattern associated with a specified J2EE feature
Section 9: Messaging
- Identify scenarios that are appropriate to implementation using messaging, EJB, or both.
- List benefits of synchronous and asynchronous messaging.
- Select scenarios from a list that are appropriate to implementation using synchronous and asynchronous messaging.
Section 10: Internationalization
- State three aspects of any application that might need to be varied or customized in different deployment locales.
- Match the following features of the Java 2 platform with descriptions of their functionality, purpose or typical uses: Properties, Locale, ResourceBundle, Unicode, java.text package, InputStreamReader and OutputStreamWriter.
Section 11: Security
- Select from a list security restrictions that Java 2 environments normally impose on applets running in a browser.
- Given an architectural system specification, identify appropriate locations for implementation of specified security features, and select suitable technologies for implementation of those features.
