Deep Dive into the Oracle 1Z0-900 Syllabus Topics
The `Oracle 1Z0-900 syllabus` is extensive, covering a broad spectrum of Java EE 7 technologies. Each topic represents a critical area of expertise for a Java EE Application Developer. Let's break down these core areas to understand their importance and what they entail for the exam.
Understand Java EE Architecture
This foundational topic sets the stage by exploring the core components, tiers, and concepts of Java EE 7 architecture. You need to understand the roles of containers (Web, EJB, Application Client), the purpose of different APIs (e.g., Servlets, JSPs, EJBs, JPA), and how they interact within an application server. Familiarity with the Java EE platform's overarching design principles is key to building scalable and maintainable enterprise applications.
Manage Persistence using JPA Entities and BeanValidation
Persistence is crucial for any enterprise application that interacts with a database. This section focuses on the Java Persistence API (JPA) for object-relational mapping. You'll need to understand how to define entities, manage relationships (one-to-one, one-to-many, many-to-many), use EntityManagers for CRUD operations, and apply JPQL (Java Persistence Query Language) or Criteria API for complex queries. Additionally, BeanValidation (JSR 303) is essential for enforcing data integrity at the model layer, ensuring that your entities meet specified constraints before persistence.
Implement Business Logic by Using EJBs
Enterprise JavaBeans (EJBs) are a cornerstone for implementing transactional business logic in Java EE applications. This topic covers different EJB types: Session Beans (Stateless, Stateful, Singleton) for business methods, Message-Driven Beans (MDBs) for asynchronous message processing, and Timer Service for scheduling tasks. Understanding their lifecycle, transaction management (declarative vs. programmatic), security implications, and how to inject and invoke them is vital for the exam.
Use Java Message Service API
The Java Message Service (JMS) API provides a robust way for Java applications to create, send, receive, and read messages asynchronously. You'll be tested on your knowledge of JMS domains (Point-to-Point and Publish/Subscribe), understanding concepts like queues and topics, and how to produce and consume messages reliably. This is particularly important for building loosely coupled, distributed systems.
Implement SOAP Services by Using JAX-WS and JAXB APIs
Web Services, specifically SOAP-based services, are a common way to enable communication between disparate applications. This section focuses on JAX-WS (Java API for XML Web Services) for creating and consuming SOAP web services, and JAXB (Java Architecture for XML Binding) for mapping Java objects to XML and vice versa. Expect questions on defining service endpoints, generating client proxies, and handling data serialization/deserialization.
Create Java Web Applications using Servlets
Servlets are fundamental components for handling HTTP requests and generating dynamic web content. This topic covers the Servlet lifecycle, request dispatching, session management, context parameters, initialization parameters, and filter chains. A strong understanding of how Servlets process requests and responses is essential for building robust web applications.
Create Java Web Applications using JSPs
JavaServer Pages (JSPs) are used for creating dynamic web pages. While Servlets handle the controller logic, JSPs are typically used for the view layer. You need to understand JSP syntax, directives, scripting elements (though often discouraged in modern practice), standard actions, and how to integrate JSPs with Servlets and custom tag libraries to create modular and maintainable user interfaces.
Implement REST Services using JAX-RS API
Representational State Transfer (REST) services are widely used for building APIs due to their simplicity and stateless nature. JAX-RS (Java API for RESTful Web Services) is the standard Java EE API for creating RESTful web services. This section requires knowledge of HTTP methods (GET, POST, PUT, DELETE), URI path templates, media types, `@Path`, `@GET`, `@POST`, `@Consumes`, `@Produces` annotations, and how to design and implement RESTful resources.
Create Java Applications using WebSockets
WebSockets provide a full-duplex communication channel over a single TCP connection, enabling real-time, interactive web applications. You'll need to understand the WebSocket API, how to create endpoint classes, handle messages, manage sessions, and send data between clients and servers in both text and binary formats. This is crucial for applications requiring instant updates and persistent connections.
Develop Web Applications using JSFs
JavaServer Faces (JSF) is a component-based UI framework for building web applications. This topic covers the JSF lifecycle, managed beans (including CDI integration), UI components, navigation rules, event handling, and validation. Understanding how to build interactive user interfaces with JSF components and integrate them with backend logic is a key part of the exam.
Secure Java EE 7 Applications
Security is paramount in enterprise applications. This section covers various security mechanisms within Java EE 7, including authentication (form-based, basic, client-certificate), authorization (declarative and programmatic), security roles, and how to configure security realms. You should also understand how to use annotations like `@RolesAllowed` and `@PermitAll` to control access to resources and methods.
Use CDI Beans
Contexts and Dependency Injection (CDI) is a powerful specification for dependency injection, lifecycle management, and contextual events within Java EE. You need to understand how to define and use CDI beans, apply scopes (e.g., `@RequestScoped`, `@SessionScoped`, `@ApplicationScoped`), use producers and disposers, interceptors, and decorators. CDI significantly simplifies application development and promotes loose coupling.
Use Concurrency API in Java EE 7 Applications
The Concurrency API (JSR 236) provides managed executors and scheduled executor services within the Java EE environment. This allows developers to submit long-running tasks or scheduled tasks that are managed by the container, benefiting from transaction and security contexts. Understanding how to use `@Asynchronous` and `ManagedExecutorService` for parallel processing and background tasks is important.
Use Batch API in Java EE 7 Applications
The Batch API (JSR 352) introduces a standard way to implement batch processing in Java EE applications. This involves breaking down large-scale, long-running tasks into manageable steps and chunks, often involving reading, processing, and writing data. You'll need to understand job specification language (JSL), job operators, step definitions, readers, processors, and writers, and how to deploy and manage batch jobs.
