Servlets y JSPs: Domina las tecnologías Java Web y Java EE |Simpliv

Do not program problems, design Java Web Solutions

Has it happened to you that in your projects you find Java applications with JSP pages that have bad practices and no structure in the Java code , making everything very difficult to understand? Forget that!!! In this course we will teach you step by step and from scratch how to develop Web applications with Servlets and JSPs, applying design patterns such as MVC (Model-View-Controller) and best practices when developing Professional and Real-World Web Java applications.

But … Why learn Servlets and JSPs?

Over the years, the Java programming language is one of the most used worldwide.

Creating mission-critical, robust, flexible and reliable systems has been one of the great challenges in the development of custom software. Today Java continues to prove to be a platform on which to support us to create this type of systems.

In addition, Java has one of the largest communities worldwide and is TOTALLY FREE OF USE.

JSP’s technology and Servlets generate hundreds of national and international job offers .
Our Methodology

In Global Mentoring we are aware that the best way to convey our experience in the development of Java Systems is through eLearning courses with videos step by step and at your own pace.

This allows new students to increase their technical skills, with the aim of obtaining better opportunities in the Java labor market, which is constantly growing and provides excellent financial compensation.

Creation of the HolaMundo Servlet exercise and we will explain in detail the creation of this Java Servlet class
Module II Basic Concepts of Servlets

We will review the basics of Servlets, requests and HTTP headers, as well as the status codes in the responses that we will handle in our HTTP requests.

We will study the Servlet Life Cycle
We will review how to process the parameters in an HTTP request and how to generate the response to the client with the help of the Servlets.
We will analyze the structure of a Web application and each of the components involved so that the Java Web server can run our application.
We will study headers involved in an HTTP request.
We will perform an exercise involving HTML forms to show the processing of parameters, header processing and status codes in an HTTP request.
Module III Session Management with Servlets

We will see the need for session management in a web application and how to use this concept through the Servlets API.

We will study the reason for the management of Sessions in a WEB application.
We will review the Handling of Cookies and URL Rewritting, which are two mechanisms with which we will handle the WEB sessions.
We will learn the use of the HttpSession object which will allow us to manage the WEB sessions in a simpler way.
We will create an example of a Shopping Cart to implement the concept of Sessions in our Java Web application.
Module IV Basic Concepts of JSPs

In this module we will learn the bases to create JSP pages and several of its elements, such as Scriptlets, Directives, among several other elements.

We will see the basic concepts JSPs with the objective of generating dynamic content from our WEB application.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Top 5 Java Web Application Technologies You Should Master in 2021

Web Development in Java

Java is a commonly used language for web development, especially on the server-side. Java web applications are distributed applications that run on the internet. Web development with Java allows us to create dynamic web pages where users can interact with the interface.

There are various ways through which you can create dynamic web pages in Java. The Java EE (Enterprise Edition) platform provides various Java technologies for web development to developers. Services like distributed computing, web services, etc. are provided by Java EE. Applications can be developed in Java without using any additional scripting language. Let us see how web applications are made via Java.

Going Beyond Java 8: Local Variable Type Inference (var) - DZone Java

According to some surveys, such as JetBrains’s great survey, Java 8 is currently the most used version of Java, despite being a 2014 release.

What you are reading is one in a series of articles titled ‘Going beyond Java 8,’ inspired by the contents of my book, Java for Aliens. These articles will guide you step-by-step through the most important features introduced to the language, starting from version 9. The aim is to make you aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.

In this article, we will talk about the most important new feature introduced with Java 10. Officially called local variable type inference, this feature is better known as the **introduction of the word **var. Despite the complicated name, it is actually quite a simple feature to use. However, some observations need to be made before we can see the impact that the introduction of the word var has on other pre-existing characteristics.

Spring Boot and Java 16 Records

In this article, we will discuss Java 16’s newest feature, Records. Then we will apply this knowledge and use it in conjunction with a Spring Boot application.

On March 16th, 2021, Java 16 was GA. With this new release, tons of new exciting features have been added. Check out the release notes to know more about these changes in detail. This article’s focus will be on Java Records, which got delivered with JEP 395. Records were first introduced in JDK 14 as a preview feature proposed by JEP 359, and with JDK 15, they remained in preview with JEP 384. However, with JDK 16, Records are no longer in preview.

I have picked Records because they are definitely the most favored feature added in Java 16, according to this Twitter poll by Java Champion Mala Gupta.

I also conducted a similar survey, but it was focused on features from Java 8 onwards. The results were not unexpected, as Java 8 is still widely used. Very unfortunate, though, as tons of new features and improvements are added to newer Java versions. But in terms of features, Java 8 was definitely a game-changer from a developer perspective.

So let’s discuss what the fuss is about Java Records.
