  3. RMI-JRMP

  4. Java IDL

  5. RMI-IIOP

  6. EJB

  7. Servlets

  8. JSP

  9. JMS

JSRs
JavaEE technologies
first exam based on:
J2EE 1.2so the followings applies:


JDBC 2.0
RMI-IIOP 1.0? because it is no longer supported?
EJB 1.1
Servlets 2.2? 2.3
JSP 1.1? 1.2
JMS 1.0? JMS 1.0.x and 1.1
JNDI 1.2 (JNDI 1.2 has been integrated into J2SE releases since J2SE 1.3)
JTA 1.0 (1.0.1a or 1.0.1B?)
JavaMail 1.0 (1.2?)
JAF 1.0


In any case it seems that the real headache is to figure out what version has to be used.

First exam objectives

1. Concepts
1.1 Draw UML Diagrams
1.2 Interpret UML diagrams.
1.3 State the effect of encapsulation, inheritance, and use of interfaces on architectural characteristics.
2. Common Architectures
2.1 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.
2.2 Recognize the effect of each of the following characteristics on J2EE technology: scalability maintainability, reliability, availability, extensibility, performance, manageability, and security.
2.3 Given an architecture described in terms of network layout, list benefits and potential weaknesses associated with it.
3. Legacy Connectivity
3.1 Distinguish appropriate from inappropriate techniques for providing access to a legacy system from Java code given an outline description of that legacy system
4. Enterprise JavaBeans Technology
4.1 List the required classes/interfaces that must be provided for an EJB technology.
4.2 Distinguish stateful and stateless Session beans.
4.3 Distinguish Session and Entity beans.
4.4 Recognize appropriate uses for Entity, Stateful Session, and Stateless Session beans.
4.5 State benefits and costs of Container Managed Persistence.
4.6 State the transactional behavior in a given scenario for an enterprise bean method with a specified transactional deployment descriptor.
4.7 Given a requirement specification detailing security and flexibility needs, identify architectures that would fulfill those requirements.
4.8 Identify costs and benefits of using an intermediate data-access object between an entity bean and the data resource.
5. Enterprise JavaBeans Container Model
5.1 State the benefits of bean pooling in an EJB container.
5.2 State the benefits of Passivation in an EJB container.
5.3 State the benefit of monitoring of resources in an EJB container.
5.4 Explain how the EJB container does lifecycle management and has the capability to increase scalability.
6. Protocols
6.1 Given a scenario description, distinguish appropriate from inappropriate protocols to implement that scenario.
6.2 Identify a protocol, given a list of some of its features, where the protocol is one of the following: HTTP, HTTPS, IIOP, JRMP.
6.2 Select from a list, common firewall features that might interfere with the normal operation of a given protocol.
7. Applicability of J2EE Technology
7.1 Select from a list those application aspects that are suited to implementation using J2EE.
7.2 Select from a list those application aspects that are suited to implementation using EJB.
7.3 Identify suitable J2EE technologies for the implementation of specified application aspects. 8. Design Patterns
8.1 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.
8.2 State the benefits of using design patterns.
8.3 State the name of a design pattern (for example, Gamma) given the UML diagram and/or a brief description of the pattern's functionality.
8.4 Select from a list benefits of a specified design pattern (for example, Gamma).
8.5 Identify the design pattern associated with a specified J2EE feature
9. Messaging
9.1 Identify scenarios that are appropriate to implementation using messaging, EJB, or both.
9.2 List benefits of synchronous and asynchronous messaging.
9.3 Select scenarios from a list that are appropriate to implementation using synchronous and asynchronous messaging.
10. Internationalization
10.1 State three aspects of any application that might need to be varied or customized in different deployment locales.
10.2 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
11.1 Select from a list security restrictions that Java 2 environments normally impose on applets running in a browser.
11.2 Given an architectural system specification, identify appropriate locations for implementation of specified security features, and select suitable technologies for implementation of those features.

at least I've made a decision

After more than three years from passing the SCJP I've finally made a decision: it is time to take the SCEA
I've used the blogs in the past for keeping roadmaps and tracking the path during the learning process of various issues so I'll do the same this time.
