Apache Tomcat is a free and open-source implementation of the Jakarta Servlet, Jakarta Expression Language, and WebSocket technologies. It provides a "pure Java" HTTP web server environment in which Java code can also run. Thus it is a Java web application server, although not a full JEE application server.
NetBeans is an integrated development environment (IDE) for Java. NetBeans allows applications to be developed from a set of modular software components called modules. NetBeans runs on Windows, macOS, Linux and Solaris. In addition to Java development, it has extensions for other languages like PHP, C, C++, HTML5, and JavaScript. Applications based on NetBeans, including the NetBeans IDE, can be extended by third party developers.
Jakarta Faces, formerly Jakarta Server Faces and JavaServer Faces (JSF) is a Java specification for building component-based user interfaces for web applications. It was formalized as a standard through the Java Community Process as part of the Java Platform, Enterprise Edition. It is an MVC web framework that simplifies the construction of user interfaces (UI) for server-based applications by using reusable UI components in a page.
JDeveloper is a freeware IDE supplied by Oracle Corporation. It offers features for development in Java, XML, SQL and PL/SQL, HTML, JavaScript, BPEL and PHP. JDeveloper covers the full development lifecycle from design through coding, debugging, optimization and profiling to deploying.
OpenLaszlo is a discontinued open-source platform for the development and delivery of rich web applications. It is released under the Open Source Initiative certified Common Public License (CPL).
Apache Geronimo is an open source application server developed by the Apache Software Foundation and distributed under the Apache license.
A Java Portlet Specification defines a contract between portlets and their containers; they provides a convenient programming model for Java portlet developers. It is defined through various Java Specification Requests (JSRs).
Echo is a web application framework created by the company NextApp. The latest iteration, Echo3, allows writing applications in either server-side Java or client-side JavaScript. Server-side applications do not require developer knowledge of HTML, HTTP, or JavaScript. Client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX.
Comet is a web application model in which a long-held HTTPS request allows a web server to push data to a browser, without the browser explicitly requesting it. Comet is an umbrella term, encompassing multiple techniques for achieving this interaction. All these methods rely on features included by default in browsers, such as JavaScript, rather than on non-default plugins. The Comet approach differs from the original model of the web, in which a browser requests a complete web page at a time.
Apache MyFaces is an Apache Software Foundation project that creates and maintains an open-source JavaServer Faces implementation, along with several libraries of JSF components that can be deployed on the core implementation. The project is divided into several sub-projects:
The Jakarta Expression Language is a special purpose programming language mostly used in Jakarta EE web applications for embedding and evaluating expressions in web pages. The specification writers and expert groups of the Java EE web-tier technologies have worked on a unified expression language which was first included in the JSP 2.1 specification (JSR-245), and later specified by itself in JSR-341, part of Java EE 7.
Seam was a web application framework developed by JBoss, a division of Red Hat.
RichFaces was an open source Ajax-enabled component library for JavaServer Faces, hosted by JBoss. It allows easy integration of Ajax capabilities into enterprise application development. It reached its end-of-life in June 2016.
JBoss Developer Studio (JBDS) is a development environment created and currently developed by JBoss and Exadel.
Ajax4jsf was a project for an open source framework that added Ajax capabilities to the JavaServer Faces (JSF) web application framework.
In computing, Facelets is an open-source Web template system under the Apache license and the default view handler technology for Jakarta Faces. The language requires valid input XML documents to work. Facelets supports all of the JSF UI components and focuses completely on building the JSF component tree, reflecting the view for a JSF application.
XPages is an IBM implementation of JavaServer Faces with a server side JavaScript runtime and the built-in NoSQL database IBM Domino. It allows data from IBM Notes and Relational Databases to be displayed to browser clients on all platforms.
ZK is an open-source Ajax Web application framework, written in Java, that enables creation of graphical user interfaces for Web applications with little required programming knowledge.
The JBoss Enterprise Application Platform is a subscription-based/open-source Java EE-based application server runtime platform used for building, deploying, and hosting highly-transactional Java applications and services developed and maintained by Red Hat. The JBoss Enterprise Application Platform is part of Red Hat's Enterprise Middleware portfolio of software. Because it is Java-based, the JBoss application server operates across platforms; it is usable on any operating system that supports Java. JBoss Enterprise Application Platform was originally called JBoss and was developed by the eponymous company JBoss, acquired by Red Hat in 2006.
