Java Specification Requests
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 platform. New members are encouraged to engage actively and play a crucial role in supporting the Java community and its releases. It is essential that m ...

Java (software Platform)
Java is a set of computer software and specifications that provides a software platform for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. Java applets, which are less common than standalone Java applications, were commonly run in secure, Sandbox (computer security), sandboxed environments to provide many features of native applications through being embedded in HTML pages. Writing in the Java (programming language), Java programming language is the primary way to produce code that will be deployed as Java byte code, byte code in a Java virtual machine (JVM); byte code compilers are also available for other languages, including Ada (programming language), Ada, JavaScript, Kotlin (programming language), Kotlin (Google's preferred Android language), Python (programming language), Python, and Ruby (p ...

Java Architecture For XML Binding
Jakarta XML Binding (JAXB; formerly Java Architecture for XML Binding) is a software framework that allows Java EE developers to map Java classes to XML representations. JAXB provides two main features: the ability to ''marshal'' Java objects into XML and the inverse, i.e. to ''unmarshal'' XML back into Java objects. In other words, JAXB allows storing and retrieving data in memory in any XML format, without the need to implement a specific set of XML loading and saving routines for the program's class structure. It is similar to xsd.exe and XmlSerializer in the .NET Framework. JAXB is particularly useful when the specification is complex and changing. In such a case, regularly changing the XML Schema definitions to keep them synchronised with the Java definitions can be time-consuming and error-prone. JAXB is one of the APIs in the Jakarta EE platform (formerly Java EE), part of the Java Web Services Development Pack (JWSDP), and one of the foundations for WSIT. It was also ...

JavaServer Pages
Jakarta Server Pages (JSP; formerly JavaServer Pages) is a collection of technologies that helps software developers create dynamically generated web pages based on HTML, XML, SOAP, or other document types. Released in 1999 by Sun Microsystems, JSP is similar to PHP and ASP, but uses the Java programming language. To deploy and run Jakarta Server Pages, a compatible web server with a servlet container, such as Apache Tomcat or Jetty, is required. Overview Architecturally, JSP may be viewed as a high-level abstraction of Jakarta Servlets. JSPs are translated into servlets at runtime, therefore JSP is a Servlet; each JSP servlet is cached and re-used until the original JSP is modified. Jakarta Server Pages can be used independently or as the view component of a server-side model–view–controller design, normally with JavaBeans as the model and Java servlets (or a framework such as Apache Struts) as the controller. This is a type of Model 2 architecture. JSP allows Ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Servlet
A Jakarta Servlet, formerly Java Servlet is a Java (programming language), Java software component that extends the capabilities of a server (computing), server. Although servlets can respond to many types of requests, they most commonly implement web containers for hosting web applications on web servers and thus qualify as a server-side servlet web API. Such web servlets are the Java (software platform), Java counterpart to other dynamic web page, dynamic web content technologies such as PHP and ASP.NET. Introduction A Jakarta Servlet is a Java class in Jakarta EE that conforms to the Jakarta Servlet API, a standard for implementing Java classes that respond to requests. Servlets could in principle communicate over any client–server model, client–server protocol, but they are most often used with Hypertext Transfer Protocol, HTTP. In principle, any servlets can extend the class; however, realistically speaking, all servlets extend the class. Thus "servlet" is often u ...

JavaServer Pages Standard Tag Library
The Jakarta Standard Tag Library (JSTL; formerly JavaServer Pages Standard Tag Library) is a component of the Java EE Web application development platform. It extends the JSP specification by adding a tag library of JSP tags for common tasks, such as XML data processing, conditional execution, database access, loops and internationalization. Specification JSTL was developed under the Java Community Process (JCP) as Java Specification Request (JSR) 52. On May 8, 2006, JSTL 1.2 was released, followed by JSTL 1.2.1 on Dec 7, 2011. In addition to JSTL, the JCP has the following JSRs to develop standard JSP tag libraries: JSR 128 JESI – JSP Tag Library for Edge Side Includes (inactive) JSR 267 JSP Tag Library for Web Services General Responsibilities JSTL provides an effective way to embed logic within a JSP page without using embedded Java code directly. The use of a standardized tag set, rather than breaking in and out of Java code, leads to more maintainable code an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Netty (software)
Netty is a non-blocking I/O client-server framework for the development of Java network applications such as protocol servers and clients. The asynchronous event-driven network application framework and tools are used to simplify network programming such as TCP and UDP socket servers. Netty includes an implementation of the reactor pattern of programming. Originally developed by JBoss, Netty is now developed and maintained by the Netty Project Community. Besides being an asynchronous network application framework, Netty also includes built-in implementations of SSL/ TLS, HTTP, HTTP/2, HTTP/3, WebSockets, DNS, Protocol Buffers, SPDY and other protocols. Netty is not a Java web container, but is able to run inside one, and supports message compression. Netty has been actively developed since 2004. Beginning with version 4.0.0, Netty also supports the usage of NIO.2 as a backend, along with NIO and blocking Java sockets. See also * Application server An application se ...

Non-blocking I/O (Java)
java.nio (NIO stands for New Input/Output) is a collection of Java programming language APIs that offer features for intensive I/O operations. It was introduced with the J2SE 1.4 release of Java by Sun Microsystems to complement an existing standard I/O. NIO was developed under the Java Community Process as JSR 51. An extension to NIO that offers a new file system API, called NIO.2, was released with Java SE 7 ("Dolphin"). Features and organization The APIs of NIO were designed to provide access to the low-level I/O operations of modern operating systems. Although the APIs are themselves relatively high-level, the intent is to facilitate an implementation that can directly use the most efficient operations of the underlying platform. The Java NIO APIs are provided in the package and its subpackages. The documentation by Oracle identifies these features. * Buffers for data of primitive types * Character set encoders and decoders * A pattern-matching facility based on Perl-styl ...

Data Logging
A data logger (also datalogger or data recorder) is an electronic device that records data over time or about location either with a built-in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer), and called digital data loggers (DDL). They generally are small, battery-powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and use software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device. Data loggers vary from general-purpose devices for various measurement applications to very specific devices for measuring in one environment or application type only. While it is common for general-purpose types to be programmable, many remain static machines with only a limited number o ...

Assertion (computing)
In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution. Assertions can help a programmer read the code, help a compiler compile it, or help the program detect its own defects. For the latter, some programs check assertions by actually evaluating the predicate as they run. Then, if it is not in fact true – an assertion failure – the program considers itself to be broken and typically deliberately crashes or throws an assertion failure exception. Details The following code contains two assertions, x > 0 and x > 1, and they are indeed true at the indicated points during execution: x = 1; assert x > 0; x++; assert x > 1; Programmers can use assertions to help specify programs and to ...

Java Metadata Interface
Given that metadata is a set of descriptive, structural and administrative data about a group of computer data (for example such as a database schema), Java Metadata Interface (or JMI) is a platform-neutral specification that defines the creation, storage, access, lookup and exchange of metadata in the Java programming language. __TOC__ History The JMI specification was developed under the Java Community Process and is defined by JSR 40 (a JSR is the formal document that describe proposed specifications and technologies for adding to the Java platform). JMI is based on the Meta-Object Facility (or MOF) specification from the Object Management Group (or OMG). The MOF is a metamodel (a model of any kind of metadata) used notably to define the Unified Modeling Language (or UML). It supports the exchange of metadata through XMI. XMI is a standard for exchanging metadata information via Extensible Markup Language (or XML). The MOF/XMI specifications are used for the exchange of U ...
