Last updated on Jan 13, 20212702The Java EE stands as an abbreviation for Java Enterprise Edition. The Java EE comes with some advanced Java specifications in collaboration with the Java Standard Edition(SE). This article is dedicated to helping you have a detailed understanding of the Java EE(Enterprise edition) through the following docket below.
Java EE is an abbreviation for Java Enterprise Edition. We can consider the Java Enterprise Edition as an upgraded version of Java SE (Standard Edition). It adds these upgrades for supporting enterprise-level developer requirements.
Following the brief introduction to Java EE, we shall now move ahead and learn why we exactly need Java EE, in the next segment.
The advanced Java specifications in Java EE are incorporated to make a few requirements meet. The following are the few significant reasons for which we need Java EE in real-time.
The Java EE since the version is consistently upgrading and finding ways to improve API and programming models for the latest applications and incorporate the features requested by the worldwide developers' community.
The primary motto of introducing the Java EE was to reduce the complexities associated with the application development time. Since the Java EE version 5, the XML Deployment descriptors have gone optional. Instead, developers enter the information in the form of an annotation directly into a Java source file. The Java EE server will assist the developer in configuring the component at deployment and runtime automatically.
These days, the developers instantly identify the necessity for distributed, transactional, and portable applications that increase server-side technology's agility, safety, and reliability. The Java EE focuses on helping enterprise applications in being designed, built, and produced with less complexity, more incredible speed, and limited cost-effectiveness resources.
Java EE has made Java enterprise application development easier or faster. The Java EE platform's motto takes pride in providing developers with a robust set of APIs. This is done while reducing development time, reducing application complexity, and improving the performance of the application.
Now that we understand precisely why we needed Java EE, let us continue and learn the various specification in which we find the implementations of Java EE in real-time.
Java EE has various specifications for different purposes. They can perform reading, writing database management, transaction processing, and web page designing.
The Java EE has four different specifications, as shown below.
We will learn about all the specifications in a more detailed way moving on.
The Java Enterprise Edition provides the software container developed to enable the injection of dependencies in Swing.
These are APIs that an object container executes to provide transactions, remote procedure calls, and concurrency control.
Persistence APIs are the specifications of object-relational mapping between relational database tables and Java classes.
Transaction API includes the interfaces and annotations to establish interaction between transaction support offered by Java EE.
Java Servlet specification defines how you can manage HTTP requests, either synchronously or asynchronously.
Java WebSocket is a communication protocol. Web socket API provides a set of APIs to facilitate WebSocket connections.
Java Server Faces are the services that help in the building of GUI out of Server components.
Unified Expression Language is a simple language that was specifically designed to facilitate web application developers.
RESTful API Web Service helps in providing services having Representational State Transfer schema.
JSON Processing is a combination of specifications to manage the information provided in JSON format.
JSON Binding is a set of specifications used for binding or parsing a JSON file into Java classes.
JSON Binding allows binding of XML into Java objects.
The Validation package contains various interfaces and annotations for declarative validation support offered by Bean Validation API.
The Validation package contains various interfaces and annotations for declarative validation support offered by Bean Validation API.
Java EE Connector is a Java-based technological solution for connecting Java servers to Enterprise Information System.
The Java EE specifications will now understand the minimum hardware requirements to install Java EE into our local system.
The following are hardware requirements you need to have in your local system to install Java EE.
Followed by the Hardware Specification, we will now learn how to install and configure Java EE into our local environment.
To install and set up the Java EE environment in our local Windows Operating system, we need to follow the steps below.
For a detailed and elaborate explanation of installing Java into your local windows operating system, please refer to the following article.
