Web.xml
A deployment descriptor (DD) refers to a configuration file for an Artifact (software development), artifact that is deployed to some Web container, container/engine. In the Java Platform, Enterprise Edition, a deployment descriptor describes how a component, module or application (such as a web application or enterprise application) should be deployed."The Java EE 5 Tutorial: Packaging Applications" retrieved 2010-07-13 It directs a deployment tool to deploy a module or application with specific container options, security settings and describes specific configuration requirements. XML is used for the syntax of these deployment descriptor files. For web applications, the deployment descriptor must be called ''web.xml'' and must reside in the ''WEB-INF'' directory in the web ...

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 ...

EAR (file Format)
EAR (''Enterprise'' ''Archive'') is a file format used by Jakarta EE for packaging one or more modules into a single archive so that the deployment of the various modules onto an application server happens simultaneously and coherently. It also contains XML files called deployment descriptors which describe how to deploy the modules. Ant, Maven, or Gradle can be used to build EAR files. File structure An EAR file is a standard JAR file (and therefore a Zip file) with an .ear extension, with one or more entries representing the modules of the application, and a metadata directory called META-INF which contains one or more deployment descriptors. * META-INF/ ** application.xml: This is the main deployment descriptor for the EAR. It lists all the modules included in the EAR and specifies configuration settings. ** MANIFEST.MF: The manifest file that provides metadata about the archive. * JAR Files: ** These files contain Enterprise JavaBeans (EJB) modules or utility classes ...

Configuration File
A configuration file, a.k.a. config file, is a computer file, file that stores computer data, data used to configure a software system such as an application software, application, a server (computing), server or an operating system. Some applications provide a tool to create, modify, and verify the syntax of their configuration files sometimes via graphical user interface (GUI). For context, system administrators may be expected to create and modify plain text, text config files via a text editor. For server processes and operating-system settings, there is often no standard tool, but operating systems may provide graphical interfaces such as YaST or debconf. Some computer programs only read their configuration files at Booting, startup. Others periodically check the configuration files for changes. Users can instruct some programs to re-read the configuration files and apply the changes to the current process, or indeed to read arbitrary files as a configuration file. There ar ...

Artifact (software Development)
An artifact is one of many kinds of ''tangible'' by-products produced during the development of software. Some artifacts (e.g., use cases, class diagrams, requirements and design documents) help describe the function, architecture, and design of software. Other artifacts are concerned with the process of development itself—such as project plans, business cases, and risk assessments. The term ''artifact'' in connection with software development is largely associated with specific development methods or processes e.g., Unified Process. This usage of the term may have originated with those methods. Build tools often refer to source code compiled for testing as an artifact, because the executable is necessary to carrying out the testing plan. Without the executable to test, the testing plan artifact is limited to non-execution based testing. In non-execution based testing, the artifacts are the walkthroughs, inspections and correctness proofs. On the other hand, execution ba ...

Web Container
A web container (also known as a servlet container; and compare "webcontainer" ) is the component of a web server that interacts with Jakarta Servlets. A web container is responsible for managing the lifecycle of servlets, mapping a URL to a particular servlet and ensuring that the URL requester has the correct access-rights. A web container handles requests to servlets, Jakarta Server Pages (JSP) files, and other types of files that include server-side code. The Web container creates servlet instances, loads and unloads servlets, creates and manages request and response objects, and performs other servlet-management tasks. A web container implements the web component contract of the Jakarta EE architecture. This architecture specifies a runtime environment for additional web components, including security, concurrency, lifecycle management, transaction, deployment, and other services.

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] |
Web Application
A web application (or web app) is application software that is created with web technologies and runs via a web browser. Web applications emerged during the late 1990s and allowed for the server to dynamically build a response to the request, in contrast to static web pages. Web applications are commonly distributed via a web server. There are several different tier systems that web applications use to communicate between the web browsers, the client interface, and server data. Each system has its own uses as they function in different ways. However, there are many security risks that developers must be aware of during development; proper measures to protect user data are vital. Web applications are often constructed with the use of a web application framework. Single-page applications (SPAs) and progressive web apps (PWAs) are two architectural approaches to creating web applications that provide a user experience similar to native apps, including features such as smoo ...

Enterprise Application
Enterprise software, also known as enterprise application software (EAS), is computer software used to satisfy the needs of an organization rather than its individual users. Enterprise software is an integral part of a computer-based information system, handling a number of business operations, for example to enhance business and management reporting tasks, or support production operations and back office functions. Enterprise systems must process information at a relatively high speed. Services provided by enterprise software are typically business-oriented tools. As companies and other organizations have similar departments and systems, enterprise software is often available as a suite of customizable programs. Function-specific enterprise software uses include database management, customer relationship management, supply chain management and business process management. Definitions and industry The term ''enterprise software'' is used in industry, and business research publica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun GlassFish Enterprise Server
GlassFish is an open-source Jakarta EE platform application server project started by Sun Microsystems, then sponsored by Oracle Corporation, and now living at the Eclipse Foundation and supported by OmniFish, Fujitsu and Payara. The supported version under Oracle was called Oracle GlassFish Server. GlassFish is free software and was initially dual-licensed under two free software licences: the Common Development and Distribution License (CDDL) and the GNU General Public License (GPL) with the Classpath exception. After having been transferred to Eclipse, GlassFish remained dual-licensed, but the CDDL license was replaced by the Eclipse Public License (EPL). Overview GlassFish is the Eclipse implementation of Jakarta EE (formerly the reference implementation from Oracle) and as such supports Jakarta REST, Jakarta CDI, Jakarta Security, Jakarta Persistence, Jakarta Transactions, Jakarta Servlet, Jakarta Faces, Jakarta Messaging, etc. This allows developers to create e ...

Manifest File
In computer programming, a manifest file is a Data file, file containing metadata for a group of accompanying files that are part of a set or coherent unit. For example, the files of a computer program may have a manifest describing the name, Software versioning, version number, Software license, license and the constituent files of the program. The term "manifest" is borrowed from a cargo shipping procedure, where a Manifest (transportation), ship manifest would list the crew and/or cargo of a vessel. Manifest files are similar in nature to Declaration (computer programming) , declaration files in that both specify the expected structure of a computer program to be consumed by another computer program, providing additional information that allow system software, software-defined tools (e.g., compilers, Lint (software), linters), Integrated development environment, development environments, or other developers to understand how to interact with certain resources or code.
