The Java Enterprise Edition (Java EE) is a Java platform built on top of the Java Standard Edition (Java SE). It provides a Runtime environment and an API. Java EE is the popular platform if you wish to build large-scale, multi-tiered, scalable, and reliable network applications. As part of the Java ecosystem, Java EE comes with additional development tools, deployment technologies, and class libraries. This learning path will start you on your journey to developing applications with Java EE.... Read more Read less
In this section, you will explore Java EE, how it fits into the Java software development landscape, and how you could use it to build your own large-scale applications.
What is Java EE, how does it compare to the Java language, should you transition to it, and which type of application would benefit from it? This course answers those questions by taking a 10,000 foot view of the Java EE landscape as well as showing some details of its programming model.
Turn a blank page into a web application! In this course, Java EE: Getting Started, you'll learn how to develop a distributed web application based on two complementary technologies: Java EE and Angular. First, you'll begin by covering how to setup your development environment, design your domain model, map it to a relational database, bring transaction management, and then expose the business domain through a REST API. Along the way, you'll make sure the integration tests always pass. Finally, once the REST API is tested, documented, and up-and-running, you'll build an Angular front-end to interact with it through HTTP and JSon. By the end of this course, you'll have the fundamental knowledge to start building REST API's with Java EE and consuming them with Angular.
Java EE 7 has established itself as the preeminent Java stack for web and back-end developers. This code-focused course shows how to build a complete application covering most of the Java EE 7 specifications. You'll learn about how the Java EE platform has progressed through its history to the modern platform it is today, the foundations of building a web application in Java EE, and how to interoperate Java EE applications with external services. You'll also learn about architectural best practices when building a Java EE application. By the end of this course, you'll have a solid foundational for building Java EE applications of your own.
Now that you have a good grasp of what Java EE enables you to do, it’s time to move to the next step. You will get up close and personal with JPA, Bean Validation, and RESTful Services in this section.
Applications are made up of business logic, interaction with other systems, user interfaces, and data. Most data manipulated by our Java applications have to be stored in databases, retrieved, and analyzed. In this course, you will learn the principle of object-relational mapping (ORM) and how to use Java Persistence API (JPA) to map your Java objects into relational databases.
Processing, storing, and retrieving valid data is crucial for an application, that's why validation is a common task that needs to be done in several layers of your application. In this course you will learn how Bean Validation allows developers to write constraints in a standard way and apply them everywhere (bean, properties, constructors, method parameters, and return value). You will also see how Bean Validation can be integrated in other Java EE specifications.
Web application development can be made easier by using Java servlets. In this course, Java EE: Programming Servlets, you will begin with a complet overview of servlet architecture and lifecycle. First, you'll see the configuration of a Tomcat webserver in Eclipse and you'll learn how to read the request and response headers. Next, you'll learn how filters are applied to servlets and see many details about tracking session data, web annotations, and globalizing servlets. Finally, you'll go over asynchronous programming in servlets, debugging, packing, and deployment of servlets. By the end of this course, you will have a much more complete understanding of how web development using Java servlets works. Software required: Tomcat and Eclipse.
This section contains some of the more advanced concepts. Learning about Servlets, CDI, Asynchronous RESTful services will make your Java EE skills complete.
Context and Dependency Injection takes its roots from injection frameworks and today has become a common ground for several Java EE specifications. In this course you will discover the CDI programming model and its concept of "loose coupling, strong typing." You will see that decoupling goes further by bringing interceptors and decorators to the entire platform.
At the start of the course we establish a basic "Books" API -- an API that we continually improve and build upon throughout the course. We begin by deploying to Grizzly, and then implement a series of tests with JerseyTest. These tests are also continually expanded throughout the course. We explore Jersey's built-in dependency injection, and improve our API to take advantage of Jersey's async support. We switch from the built-in MOXy library in favor of Jackson to render our highly-tailored JSON and XML, and build a custom MessageBodyWriter along the way. We explore mapping exceptions to responses, and supporting conditional GET requests. We implement our own PATCH verb, and along with it, support for conditional updates as well. Finally we explore Jersey's support for filters and implement our own custom filter.
It is recommended that you have basic Java knowledge.
