Java Server Pages (JSP) allow you to separate the dynamic parts of your web pages from the static HTML. You write normal HTML code using a web page authoring tool, and then enclose dynamic code sections within special tags that mostly start with "<%" and end with "%>". JSP provides various tags like scriptlets, expressions, comments, and directives to embed Java code within web pages to add dynamic functionality. Common uses of JSP include dynamically generating content, connecting to databases to retrieve and display data, and controlling the page flow based on user input.

This document is a study book for university students on the topic of Hibernate and EJB3. It was authored by Sr. Java developer Dudnik Oxana. The document provides information on entity mapping using JPA annotations, defines the persistence unit in the persistence.xml file, and shows an example of basic CRUD operations using an EntityManager.
Java Server Faces (JSF) is a web application framework that uses XHTML markup and allows building user interfaces for Java-based web applications. The document discusses the JSF architecture which follows the Model-View-Controller pattern and includes XHTML files, CSS/JavaScript resources, servlet configuration files, class files, and library files. It then provides an example of creating a simple JSF project to convert meters to inches that displays the result on screen after configuring JBoss and starting the application.
The document discusses setting up Docker and DevOps tools. It describes installing Docker Toolbox, creating a docker machine, setting environment variables, creating a network, starting docker-compose, generating SSL certificates, and accessing the Docker host URL. It also discusses creating a Jenkins job to generate other jobs for building, deploying, and monitoring a project from a Git repository using a Groovy script and the Job DSL plugin. References for the Job DSL plugin and scripting are provided.
To work with an Oracle database in Java, one must first download and install Oracle from the provided website. This will start the database configuration assistant. Then a new ADMIN user must be created and the connection properties changed. Finally, in IntelliJ Idea the Oracle data source must be selected from the database window.

This document discusses how to work with XML files in Java. It provides examples of using JAXB to generate XML files from Java objects and parse XML files into Java objects. Code samples are given to demonstrate how to:
1) Create a Java class to represent an employee object and annotate it for XML conversion
2) Write a program that takes an employee object and generates an XML file
3) Create Java classes to represent objects in an XML file containing a list of horses and their attributes
4) Use JAXB to export a list of horse objects to an XML file and import an XML file back into a list of horse objects.
The document discusses setting up Docker Toolbox and creating a Docker machine to run Docker containers. It provides steps to install Docker Toolbox, create a Docker machine, set environment variables, create a Docker network, start Docker Compose, and generate SSL certificates. It also discusses using Jenkins Job DSL plugins to generate Jenkins jobs for building, deploying, and managing a sample project with Docker containers.

In the automation world, W3C Webdriver HTTP protocol has been successfully used for a long time. With its help, many projects and libraries in various languages have been implemented (selenide, protractor, webdriverio and thousands of others). But more and more teams decide to use Chrome Debug Protocol, in particular the Puppeteer tool. It is based on WebSockets, and has its own special features two-way communication, ability to subscribe to events in the browser, and much more. In this talk, we will look at the capabilities of both protocols, experiment and combine them together in one project to make the browser work at full power, and take the best from both communication channels.

About Spring in pictures.
Spring is the most popular application development framework for enterprise Java. Millions of developers around the world use Spring Framework to create high performing, easily testable, reusable code.
Spring framework is an open source Java platform and it was initially written by Rod Johnson and was first released under the Apache 2.0 license in June 2003.
Spring is lightweight when it comes to size and transparency. The basic version of spring framework is around 2MB.
