Java Logging Frameworks
A Java logging framework is a computer data logging package for the Java platform. This article covers general purpose logging frameworks. Logging refers to the recording of activity by an application and is a common issue for development teams. Logging frameworks ease and standardize the process of logging for the Java platform. In particular they provide flexibility by avoiding explicit output to the console (see Appender below). Where logs are written becomes independent of the code and can be customized at runtime. Unfortunately the JDK did not include logging in its original release so by the time the Java Logging API was added several other logging frameworks had become widely used – in particulaApache Commons Logging(also known as Java Commons Logging or JCL) and Log4j. This led to problems when integrating different third-party libraries (JARs) each using different logging frameworks. Pluggable logging frameworks (wrappers) were developed to solve this problem.

Computer Data Logging
In computing, logging is the act of keeping a wikt:log#Etymology 2, log of Event (computing), events that occur in a computer system, such as problems, errors or just information on current operations. These events may occur in the operating system or in other software. A message or log entry is recorded for each such event. These log messages can then be used to monitor and understand the operation of the system, to debugging, debug problems, or during an audit. Logging is particularly important in multi-user software, to have a central overview of the operation of the system. In the simplest case, messages are written to a file, called a log file. Alternatively, the messages may be written to a dedicated logging system or to a log management software, where it is stored in a database or on a different computer system. Specifically, a transaction log is a log of the communications between a system and the users of that system, or a data collection method that automatically cap ...

Scalatra
Scalatra is a free and open source web application framework written in Scala. It is a port of the Sinatra framework written in Ruby. Scalatra is an alternative to the Lift, Play!, and Unfiltered frameworks. Scalatra is an example of a microframework, a web software development framework which attempts to be as minimal as possible. A full Scalatra application can be written in very few lines of code: package org.example.app import org.scalatra._ class MyScalatraFilter extends ScalatraFilter From this tiny domain-specific language, Scalatra can be expanded into a minimal but full-featured model-view-controller web framework. For example, additional libraries can be attached in order to provide templating, object-relational mapping, and unit testing or behaviour driven development support. Software built with Scalatra *LinkedIn used Scalatra to power its now-defunct Signal API. *Parts of ''The Guardian ''The Guardian'' is a British daily newspaper. It wa ...

Javolution
Javolution is a real-time library aiming to make Java or Java-Like/C++ applications faster and more time predictable. Indeed, time-predictability can easily be ruined by the use of the standard library (lazy initialization, array resizing, etc.) which is not acceptable for safety-critical systems. The open source Javolution library addresses these concerns for the Java platform and native applications. It provides numerous high-performance classes and utilities useful to non real-time applications as well. Such as: * Collections classes, supporting custom views, closure-based iterations, map-reduce paradigm, parallel computing, etc. * Worst-case execution time behavior documented using Realtime Java annotations * Fractal structures to maintain high-performance regardless of the size of the data * OSGi contexts allowing cross cutting concerns (concurrency, logging, security, ...) to be addressed at run-time through OSGi published services without polluting the application code ...

MIT License
The MIT License is a permissive free software license originating at the Massachusetts Institute of Technology (MIT) in the late 1980s. As a permissive license, it puts only very limited restriction on reuse and has, therefore, high license compatibility. Unlike copyleft software licenses, the MIT License also permits reuse within proprietary software, provided that all copies of the software or its substantial portions include a copy of the terms of the MIT License and also a copyright notice. , the MIT License was the most popular software license found in one analysis, continuing from reports in 2015 that the MIT License was the most popular software license on GitHub. Notable projects that use the MIT License include the X Window System, Ruby on Rails, Nim, Node.js, Lua, and jQuery. Notable companies using the MIT License include Microsoft ( .NET), Google ( Angular), and Meta (React). License terms The MIT License has the identifier MIT in the SPDX License List. It is ...

Shim (computing)
In computer programming, a shim is a library that transparently intercepts API calls and changes the arguments passed, handles the operation itself or redirects the operation elsewhere. Shims can be used to support an old API in a newer environment, or a new API in an older environment. Shims can also be used for running programs on different software platforms than they were developed for. Shims for older APIs typically come about when the behavior of an API changes, thereby causing compatibility issues for older applications which still rely on the older functionality; in such cases, the older API can still be supported by a thin compatibility layer on top of the newer code. Shims for newer APIs are defined as: "a library that brings a new API to an older environment, using only the means of that environment." Examples * Web polyfills implement newer web standards using older standards and JavaScript, if the newer standard is not available in a given web browser. * ...

SLF4J
Simple Logging Facade for Java (SLF4J) provides a Java logging API by means of a simple facade pattern. The underlying logging backend is determined at runtime by adding the desired binding to the classpath and may be the standard Sun Java logging package java.util.logging, Log4j, Reload4j, Logback or tinylog. The separation of the client API from the logging backend reduces the coupling between an application and any particular logging framework. This can make it easier to integrate with existing or third-party code or to deliver code into other projects that have already made a choice of logging backend. SLF4J was created by Ceki Gülcü as a more reliable alternative to Jakarta Commons Logging framework. Research in 2013 on 10,000 GitHub projects found that the most popular Java library is SLF4J, along with JUnit, with 30.7% of projects using it. In January 2021, it was ranked as the second most popular project according to mvnrepository. Similarities and differences with ...

Apache Commons Logging
Apache Commons Logging (previously known as Jakarta Commons Logging or JCL) is a Java-based logging utility and a programming model for logging and for other toolkits. It provides APIs, log implementations, and wrapper implementations over some other tools. Log level The following table defines the log levels and messages in Apache Commons Logging, in decreasing order of severity. The left column lists the log level designation in and the right column provides a brief description of each log level. Configuration Two basic abstractions, Log and LogFactory, are used in Apache Commons Logging. Example Sample code may look like as follows: package com.cascadetg.ch09; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.apache.commons.logging.impl.Jdk14Logger; public class LogGenerator See also *log4j *Chainsaw (log file viewer) Chainsaw is a java-based GUI software tool to view and analyze computer log files – specific ...

LGPL
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. The LGPL was developed as a compromise between the strong copyleft of the GNU General Public License (GPL) and more permissive licenses such as the BSD licenses and the ...

Spring Framework
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. Version history The first version was written by Rod Johnson, who released the framework with the publication of his book ''Expert One-on-One J2EE Design and Development'' in October 2002. The framework was first released under the Apache 2.0 license in June 2003. The first production release, 1.0, was released in March 2004. The Spring 1.2.6 framework won a Jolt productivity award and a JAX Innovation Award in 2006. Spring 2.0 was released in October 2006, Spring 2.5 in November 2007, Spri ...

Play Framework
Play Framework is an open-source web application framework which follows the model–view–controller (MVC) architectural pattern. It is written in Scala and usable from other programming languages that are compiled to JVM bytecode, e.g. Java. It aims to optimize developer productivity by using convention over configuration, hot code reloading and display of errors in the browser. Support for the Scala programming language has been available since version 1.1 of the framework. In version 2.0, the framework core was rewritten in Scala. Build and deployment was migrated to SBT, and templates use Scala instead of Apache Groovy. History Play was created by software developer Guillaume Bort, while working at Zengularity SA (formerly Zenexity). Although the early releases are no longer available online, there is evidence of Play existing as far back as May 2007. In 2007, pre-release versions of the project were available to download from Zenexity's website. Motivation Play is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
