Why should you learn Java EE and Web Services?
Java EE (Enterprise Edition) is a platform that provides a set of specifications and APIs for developing enterprise applications using Java. It offers features such as distributed computing, security, concurrency, transactions, persistence and web services.
Web Services are software components that communicate over the internet using standard protocols such as HTTP and XML. They enable interoperability between different systems and platforms. There are two main types of web services: SOAP (Simple Object Access Protocol) and RESTful (Representational State Transfer).
Learning Java EE and Web Services can benefit you in many ways:
You can create web applications that are robust, scalable and secure.
You can use various frameworks and tools that simplify your development process.
You can integrate your applications with other systems and services using web services.
You can enhance your resume and portfolio with advanced skills.
You can increase your chances of getting hired or promoted as a web developer.
What will you learn in Caelum FJ 31?
Caelum FJ 31 is a comprehensive course that covers the following topics and skills:
Java EE basics
You will learn how to use the core components of Java EE for web development, such as:
Servlets: Java classes that handle HTTP requests and responses.
JSPs (JavaServer Pages): HTML pages that contain Java code and tags for dynamic content.
JSTL (JavaServer Pages Standard Tag Library): A collection of tags that provide common functionality such as iteration, conditionals, formatting and database access.
EL (Expression Language): A language that allows you to access and manipulate data in JSPs and JSF pages.
MVC (Model-View-Controller): A design pattern that separates the business logic, presentation and user interaction of a web application.
Filters: Java classes that intercept and modify HTTP requests and responses before or after they reach a servlet or a JSP.
Listeners: Java classes that listen to events that occur in the web application, such as initialization, destruction, session creation and attribute changes.
Java Persistence API (JPA)
You will learn how to use JPA to map Java objects to relational database tables and perform CRUD (Create, Read, Update, Delete) operations. You will learn how to:
Define entities: Java classes that represent database tables and columns using annotations or XML.
Create persistence units: XML files that specify the database connection details and the entity classes.
Use entity managers: Java objects that manage the persistence of entities and provide methods for querying and manipulating data.
Write queries: JPQL (Java Persistence Query Language) or Criteria API expressions that retrieve data from the database based on certain criteria.
Enterprise JavaBeans (EJB)
You will learn how to use EJBs to implement the business logic of your web application using distributed components. You will learn how to:
Create session beans: EJBs that provide services to clients, such as calculations, validations, transactions and security. There are two types of session beans: stateless and stateful.
Create message-driven beans: EJBs that receive and process messages from a message queue or a topic using JMS (Java Message Service).
Use transactions: Mechanisms that ensure the consistency and integrity of data across multiple operations. You will learn how to use container-managed transactions (CMT) or bean-managed transactions (BMT).
Use security: Mechanisms that protect your web application from unauthorized access. You will learn how to use declarative security or programmatic security.
JavaServer Faces (JSF)
You will learn how to use JSF to create user interfaces for your web application using components, validators, converters, managed beans and navigation rules. You will learn how to:
Create components: UI elements that display data or accept user input, such as text fields, buttons, tables and menus. You can use standard components or custom components.
Create validators: Classes or methods that check the validity of user input, such as required fields, length limits or formats. You can use standard validators or custom validators.
Create converters: Classes or methods that convert data between different types or formats, such as numbers, dates or currencies. You can use standard converters or custom converters.
Create managed beans: Java classes that store data or perform actions for a JSF page. You can use annotations or XML to define the scope and name of a managed bean.
Create navigation rules: XML files or annotations that define the flow of control between JSF pages based on user actions or outcomes.
Web Services
You will learn how to create and consume web services using SOAP or RESTful approaches. You will learn how to:
Create SOAP web services: Web services that use XML messages and WSDL (Web Services Description Language) contracts to communicate over HTTP. You will learn how to use JAX-WS (Java API for XML Web Services) to create SOAP web services.
Create RESTful web services: Web services that use HTTP methods and URIs (Uniform Resource Identifiers) to communicate over HTTP. You will learn how to use JAX-RS (Java API for RESTful Web Services) to create RESTful web services.
