AribaWeb is the Open Source component-based web application development framework for creating rich, AJAX-enabled applications with the absolute minimum of code (and no hand-coded Javascript).

Eclipse and EMF template-based system for source-code generation from UML models. Acceleo is easy to use. It provides "off the shelf" generators (JEE, .Net, Php...) and template editors for Eclipse.

Source code documentation generator tool. Doxygen is a documentation system for C++, C, Java, Objective-C, Python, IDL (Corba and Microsoft flavors) and to some extent PHP, C#, and D.

jenabean uses Jena's flexible RDF/OWL api to persist java beans. It takes an unconventional approach to binding that is driven by the java object model rather than an OWL or RDF schema. jenabean is annotation based and does not place any interface or extension requirements on your java object model. By default jenabean uses typical java bean conventions to derive RDF property URI’s, for example, the java bean property “name” would become RDF property “hasName”. jenabean allows for explicit binding between an object property and a particular RDF property.

TestOptimal is a suite of model-based test automation tools for functional testing and load/performance testing. Find defects in the requirements and respond to changes with ease through modeling while the product is being developed. Achieve unprecedented test coverage through system generated test sequences. Track requirements coverage and visualize test cases and test coverage. TestOptimal can help you greatly reduce time to market while gaining higher confidence in your product.

All the tools software developers need to create cross-platform Java desktop, enterprise and web applications. Runs on Windows, Linux, MacOS, as well as Solaris. It is easy to install and use, works right out of the box -- and it is open-source and free!

Altova XMLSpy Enterprise Edition is the industry standard XML development environment for modeling, editing, transforming, and debugging XML-related technologies. In addition to the world's leading XML editor, XMLSpy includes the original graphical XML Schema editor, which enables you to design otherwise complex schemas with ease. Advanced error handling and dynamic hyperlinking in its XML validator make correcting XML documents a breeze. XMLSpy Enterprise Edition features a built-in code generator that auto-generates Java, C++, or C# class files from data elements defined in your schemas.

ItsNat is an innovative open source (dual licensed, GNU Affero General Public License v3/commercial license for closed source projects) Java AJAX Component based Web Framework. It offers a natural approach to the modern web development. Why natural? ItsNat leverages the old tools to build the new AJAX based Web 2.0 applications: pure (X)HTML templates, pure W3C DOM... and pure Java!. ItsNat is server centric using a unique approach called TBITS, "The Browser Is The Server": ItsNat simulates a Universal W3C Java Browser at the server, with ItsNat the server mimics the behavior of a web browser, containing a W3C DOM Level 2 node tree and receiving W3C DOM Events.

QF-Test is a cross-platform software (Windows, Linux/Unix, macOS) tool for the GUI test automation (Java/Swing, SWT, Eclipse plug-ins and RCP applications, Java applets, Java Web Start, ULC and cross-browser test automation (IE, Firefox, Chrome, Safari and Edge via WebDriver) of static and dynamic web-based applications (HTML, AJAX: ExtGWT/GXT, ExtJS, GWT, ICEfaces, jQuery UI, jQuery EasyUI, Kendo UI, PrimeFaces, Qooxdoo, RAP, RichFaces, Vaadin, ZK etc.). Further (e.g. SAP UI5, Siebel Open UI, Smart GWT, Wicket, Angular JS, AngularDart) and future web toolkits can be integrated with little effort. With the release of version branch 4.0 in 2014, JavaFX GUI testing was integrated as well. QF-Test enables regression and load testing.

Squish is the professional, cross-platform GUI testing supporting different GUI technologies. Squish enables automatic web testing of Web/HTML/Ajax applications in different web browsers (IE, Firefox, Mozilla, Safari, Konqueror) on multiple platforms. Squish also enables automated GUI testing of Java Swing/AWT, SWT/Eclipse Rich Client Platform (RCP) applications, C++ Trolltech Qt applications, Carbon/Cocoa Mac OS X applications, 4Js Genero applications, Tcl/Tk applications, XView applications and more. Squish's competetive advantage is its close integration into the GUI technology by recognizing advanced controls (trees, tablels, etc.), advanced synchronization options and making the complete toolkit's API (Web/Ajax DOM, Java, Qt, etc.) accessible from test scripts to allow creating robust and maintainable tests.
