Bean Validation
Bean Validation defines a metadata model and API for JavaBean validation. The metadata source is annotations, with the ability to override and extend the meta-data through the use of XML validation descriptors. Originally defined as part of Java EE, version 2 aims to work in Java SE apps as well. Java Bean ValidationJSR 303 originated as a framework that was approved by the JCP as of 16 November 2009 and accepted as part of the Java EE 6 specification. The Hibernate team provides with Hibernate Validator the reference implementation of Bean Validation and also created the Bean Validation TCK any implementation of JSR 303 needs to pass. Current Version Bean Validation 2.0 is defined bJSR 380 approved 2017-07-31. This major release leverages language features in Java 8 that are very useful for the purposes of Bean Validation. So Java 8 is required as the minimum Java version. Other changes include: *Support for validating container elements by annotating type arguments of paramet ...

JavaBean
In computing based on the Java Platform, JavaBeans is a technology developed by Sun Microsystems and released in 1996, as part of JDK 1.1. The 'beans' of JavaBeans are classes that encapsulate one or more objects into a single standardized object (the bean). This standardization allows the beans to be handled in a more generic fashion, allowing easier code reuse and introspection. This in turn allows the beans to be treated as software components, and to be manipulated visually by editors and IDEs without needing any initial configuration, or to know any internal implementation details. As part of the standardization, all beans must be serializable, have a zero-argument constructor, and allow access to properties using getter and setter methods. Features ;Introspection :Introspection is a process of analyzing a Bean to determine its capabilities. This is an essential feature of the Java Beans specification because it allows another application, such as a design tool, to ...

Java Annotation
In the Java computer programming language, an annotation is a form of syntactic metadata that can be added to Java source code. Class (computer programming), Classes, Method (computer programming), methods, Variable (computer science), variables, Parameter (computer programming), parameters and Java packages may be annotated. Like Javadoc tags, Java annotations can be read from source files. Unlike Javadoc tags, Java annotations can also be embedded in and read from Java class files generated by the Java compiler. This allows annotations to be retained by the Java virtual machine at Run time (program lifecycle phase), run-time and read via reflection (computer science), reflection. It is possible to create meta-annotations out of the existing ones in Java. History The Java (software platform), Java platform has various ''ad-hoc'' annotation mechanisms—for example, the ''transient'' modifier, or the ''@Deprecated'' javadoc tag.

Java Platform, Enterprise Edition
Jakarta EE, formerly Java Platform, Enterprise Edition (Java EE) and Java 2 Platform, Enterprise Edition (J2EE), is a set of specifications, extending Java SE with specifications for enterprise features such as distributed computing and web services. Jakarta EE applications are run on reference runtimes, which can be microservices or application servers, which handle transactions, security, scalability, concurrency and management of the components they are deploying. Jakarta EE is defined by its specification. The specification defines APIs (application programming interface) and their interactions. As with other Java Community Process specifications, providers must meet certain conformance requirements in order to declare their products as ''Jakarta EE compliant''. Examples of contexts in which Jakarta EE referencing runtimes are used are: e-commerce, accounting, banking information systems. History The platform created by Sun Microsystems was known as ''Java 2 Platform, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Java Platform, Standard Edition
Java Platform, Standard Edition (Java SE) is a computing platform for development and deployment of porting, portable code for desktop computer, desktop and server (computing), server environments. Java SE was formerly known as Java 2 Platform, Standard Edition (J2SE). The platform uses the Java (programming language), Java programming language and is part of the Java (software platform), Java software-platform family. Java SE defines a range of general-purpose APIs—such as List of Java APIs, Java APIs for the Java Class Library—and also includes the Java Language Specification and the Java Virtual Machine Specification. OpenJDK is the official reference implementation since version 7. Nomenclature, standards and specifications The platform was known as ''Java 2 Platform, Standard Edition'' or ''J2SE'' from version 1.2, until the name was changed to ''Java Platform, Standard Edition'' or ''Java SE'' in version 1.5. The "SE" is used to distinguish the base platform from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Framework (computer Science)
In computer programming, a software framework is a software abstraction that provides generic functionality which developers can extend with custom code to create applications. It establishes a standard foundation for building and deploying software, offering reusable components and design patterns that handle common programming tasks within a larger software platform or environment. Unlike libraries where developers call functions as needed, frameworks implement inversion of control by dictating program structure and calling user code at specific points, while also providing default behaviors, structured extensibility mechanisms, and maintaining a fixed core that accepts extensions without direct modification. Frameworks also differ from regular applications that can be modified (like web browsers through extensions, video games through mods), in that frameworks are intentionally incomplete scaffolding meant to be extended through well-defined extension points and following sp ...

Java Community Process
The Java Community Process (JCP), established in 1998, is a formal mechanism that enables interested parties to develop standard technical specifications for Java technology. Becoming a member of the JCP requires solid knowledge of the Java programming language, its specifications, and best practices in software development. Membership in the JCP involves a detailed review of the candidate's profile, including an assessment by current members. Typically, professionals are invited to join the JCP based on their contributions and reputation within the Java community. Once invited, the new member undergoes an evaluation by the JCP Executive Committee, ensuring that they can effectively contribute to the Java Specification Requests (JSRs). These formal documents describe proposed specifications and technologies to be added to the Java (software platform), Java platform. New members are encouraged to engage actively and play a crucial role in supporting the Java community and its release ...

Hibernate (Java)
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 Apache License. Versions prior to 7.0.0.Beta4 were 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. Mapping The mapping of Java classes to database tables is implemented by the configuration of an XML file or by using Java Annotations. When using an ...

Reference Implementation
In the software development process, a reference implementation (or, less frequently, sample implementation or model implementation) is a program that implements all requirements from a corresponding specification. The reference implementation often accompanies a technical standard, and demonstrates what should be considered the "correct" behavior of any other implementation of it. Characteristics and examples Reference implementations of algorithms, for instance cryptographic algorithms, are often the result or the input of standardization processes. In this function they are often dedicated to the public domain with their source code as public domain software. Examples are the first CERN's httpd, Serpent cipher, base64 variants, and SHA-3. The Openwall Project maintains a list of several algorithms with their reference source code In computing, source code, or simply code or source, is a plain text computer program written in a programming language.

Technology Compatibility Kit
A Technology Compatibility Kit (TCK) is a suite of tests that at least nominally checks a particular alleged implementation of a Java Specification Request (JSR) for compliance. It is one of the three required pieces for a ratified JSR in the Java Community Process, which are: *the JSR specification *the JSR reference implementation *the Technology Compatibility Kit (TCK) Contents and architecture TCKs tend to be obtained from the Specification Lead of a given JSR. They usually (but not always) consist of a graphical host application which communicates over TCP/IP with the device or Java virtual machine that is under test. Tests are typically obtained by the device over HTTP, and results are posted back to the host application in a similar way. This decoupling enables TCKs to be used to test virtual machines on devices such as CLDC mobile phones which do not have the power to run the full TCK host application. The tests contained in the JSR are supposedly derived from the statements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
JavaFX
JavaFX is a software platform for creating and delivering desktop applications, as well as rich web applications that can run across a wide variety of devices. JavaFX has support for desktop computers and web browsers on Microsoft Windows, Linux (including Raspberry Pi), and macOS, as well as mobile devices running iOS and Android, through Gluon Mobile. With the release of JDK 11 in 2018, Oracle made JavaFX part of the OpenJDK under the ''OpenJFX'' project, in order to increase the pace of its development. Open-source JavaFXPorts works for iOS (iPhone and iPad) and Android. 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. Features JavaFX 1.1 was based on the concept of a "common profile" that is intended to span across all devices supported by JavaFX. This approach makes it possible f ...
