JAVA Enterprise Edition Course And Certification

What is JAVA Enterprise Edition?

Java Enterprise Edition, known as JAVA EE or J2EE and is currently known as Jakarta EE.

Jakarta EE, formerly Java Platform, Enterprise Edition and Java 2 Platform. 

Java Enterprise Edition or Jakarta EE is a set of specifications, developed to extend Java SE 8 with specifications for enterprise features such as corporate distributed computing services and robust web services. 

All of the Java platforms that exist is made up of a Java Virtual Machine (VM) and an application programming interface commonly known as an API.

The Java Virtual Machine is a program, for a unique hardware and a software platform, that runs all the Java technology applications. An API is an assembly of software components that you can use to create other software components or other software applications.

Each Java platform provides a virtual machine and an API, and this allows applications that are written for that platform to be run on any compatible system with all the advantages of the Java programming language, such as being platform-independence, ease-of-development, power, stability, and security.

It is made up of application clients that have an access to the Java EE server and are usually located on a different machine than on the server. Clients are able to make requests to the server. Then, the server processes these requests and returns a response to the client. 

Different types of enterprise applications can be regarded as part of the Java EE clients; although, the clients are different Java applications such as standalone IT applications, web browsers, other servers etc. that aren run on different machines using the J2EE server. 

Features of JAVA Enterprise Edition: 

There are lots of features of the Java Enterprise Edition, and some of them are:

1. javax.servlet: This Java EE servlet defines a range of the APIs to manage and address HTTP requests. Specifications that are in this servlet are the JavaServer Pages(JSPs).
2. javax.faces: This is the root of the JavaServer Faces (JSF) API. This technology is Designed to be used when developing user interfaces by using several components. 
3. javax.websocket: This WebSocket specification is used to define APIs that are linked together with WebSocket connections.
4. javax.faces.component: This part of the JavaServer Faces API is component-oriented and it is one of its core packages. This software tool is made up of a UML diagram of component hierarchy. 
5. javax.enterprise.inject: This includes injection annotations that define beans, built-in qualifiers, stereotype, classes and interfaces that are parts of the Contexts and Dependency Injection (CDI) APIs.
6. javax.el: This package defines the classes and the user interfaces for Expression Language of Java EE. Expression Language is designed to address specific needs of developing web applications. JavaServer Faces uses this package to combine several components with backing beans and CDI makes use of it to connect components several with the name beans to be used across the software platform.
7. javax.enterprise.context: The Context annotations and interfaces that are made present under the Contexts and Dependency Injection (CDI) API are defined by this particular package. 

Why Study JAVA Enterprise Edition: 

There are several benefits of the Java Enterprise Edition, and some of them are:

1. Gain essential Java programming skills and build dynamic multi-purpose applications
2. Java can be used to generate dynamic content that appears in several formats as per the needs of the client. 
3. Java can be used to collect inputs from the client interface and return proper results from components that are made available in the business tier.
4. They can be used to control display of screens or pages on client’s interface.
5. They can be used to maintain data stability for user sessions.
6. They can be used to carry out basic logic and store some of the data temporarily in the components of JavaBeans.
7. Job opportunities and career advancement
8. Enrich your CV and increase your earning potential
