About

Java is a class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. As of 2019, Java was one of the most popular programming languages in use according to GitHub, particularly for client-server web applications, with a reported 9 million developers.

About

Hibernate ORM (or simply Hibernate) is an object-relational mapping tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database. Hibernate handles object-relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions.

Hibernate is free software that is distributed under the GNU Lesser General Public License 2.1.

Hibernate's primary feature is mapping from Java classes to database tables and mapping from Java data types to SQL data types. Hibernate also provides data query and retrieval facilities. It generates SQL calls and relieves the developer from the manual handling and object conversion of the result set.

OpenESB is a Java-based open-source enterprise service bus. It can be used as a platform for both enterprise application integration and service-oriented architecture. OpenESB allows you to integrate legacy systems, external and internal partners and new development in your Business Process. OpenESB is the unique open-source ESB relying on standard JBI (Java Business Integration), XML, XML Schema, WSDL, BPEL and Composite application that provides you with simplicity, efficiency, long-term durability, and savings on your present and future investments with a very low TCO (Total Cost of Ownership).

About

The Spring Framework is an application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE (Enterprise Edition) platform. Although the framework does not impose any specific programming model, it has become popular in the Java community as an addition to the Enterprise JavaBeans (EJB) model. The Spring Framework is open source.

About

Reusability comes at the core of any modern computer language's framework. It is often desirable to use components you previously built-in recurring environments. In Rapid Application Development, these prove more helpful as you can drag them off a list of components and use it elsewhere in your project. Such a level of reusability is added into the Java Programming language with the help of the JavaBeans architecture.

JavaBeans are the mainstream Java component model, introduced in 1996 by Sun Microsystems. JavaBeans are defined as follows:

"A JavaBean is a reusable software component that can be manipulated visually in a builder tool."

Together with the component model, Sun released a simple visual composition tool, the BeanBox. It is mostly intended for experimenting with Beans rather than offering a professional IDE. For real world applications, one should better deploy on one of the Java IDEs like Visual Age or JBuilder that supports the visual composition of JavaBeans.

About

JavaFX is a software platform for creating and delivering desktop applications, as well as rich Internet applications (RIAs) that can run across a wide variety of devices. JavaFX is intended to replace Swing as the standard GUI library for Java SE, but both will be included for the foreseeable future. JavaFX has support for desktop computers and web browsers on Microsoft Windows, Linux, and macOS.

On desktops, JavaFX supports Windows Vista, Windows 7, Windows 8, Windows 10, macOS, and Linux operating systems. Beginning with JavaFX 1.2, Oracle has released beta versions for OpenSolaris. On mobile, JavaFX Mobile 1.x is capable of running on multiple mobile operating systems, including Symbian OS, Windows Mobile, and proprietary real-time operating systems.

With the release of JDK 11 in 2018, Oracle has made JavaFX part of the OpenJDK under the OpenJFX project, in order to increase the pace of its development.^[8] Oracle support for JavaFX is also available, for the current long-term version (Java JDK 8), through March 2025.

Open-source JavaFXPorts works for iOS (iPhone and iPad) and Android and embedded (Raspberry Pi); and the related commercial software created under the name "Gluon" supports the same mobile platforms with additional features plus desktop. This allows a single source code base to create applications for the desktop, iOS, and Android devices.

There are various ways in which Java code can be executed. A complex Java application usually uses third party APIs or services. In this course, we list the most popular ways a piece of Java code may be packed together and/or executed.

JSE code execution

Java language first edition came out in the client-server era. Thick clients were developed with rich GUI interfaces. Java first edition, JSE (Java Standard Edition) had/has the following in its belt:

• GUI capabilities (AWT, Swing)
• Network computing capabilities (RMI)
• Multi-tasking capabilities (Threads)

This course is about Enterprise JavaBeans 2.1. It also covers EJB 2.0, which is still in widespread use. Just as the Java platform has revolutionized the way we think about software development, Enterprise JavaBeans has revolutionized the way we think about developing mission-critical enterprise software. It combines server-side components with distributed object technologies, asynchronous messaging, and web services to greatly simplify the task of application development. It automatically takes into account many of the requirements of business systems, including security, resource pooling, persistence, concurrency, and transactional integrity.

This course will show you how to use Enterprise JavaBeans to develop scalable, portable business systems. But before we can start talking about EJB itself, we'll need a brief introduction to the technologies addressed by EJB, such as component models, distributed objects, asynchronous messaging, and web services. It's particularly important to have a basic understanding of component transaction monitors, the technology that lies beneath EJB.
