WaveMaker
WaveMaker (formerly known as ActiveGrid) is an open source software development platform that automates much of the process for creating Java web and cloud applications. WaveMaker provides a visual rapid application development platform and is available as a free open source software download or as a hosted cloud development environment (aka Platform as a Service) running on Amazon EC2.
WaveMaker allows web developers to create Ajax applications. The WaveMaker framework itself integrates Spring, ACEGI, Dojo Toolkit 1.0, authentication, LDAP, ActiveDirectory and POJOs and their products include Visual Ajax Studio for Rich Internet applications development and WaveMaker Rapid Deployment Server for Java application.
Applications generated by WaveMaker community edition are licensed under the Apache license. WaveMaker applications are created using the WaveMaker studio, a WYSIWYG development studio that runs in a browser and enables drag and drop development of web applications following a Model-view-controller architecture. WaveMaker supports RAD for the web, similar to what products like MS Access, PowerBuilder and Lotus Notes provided for client server computing.
WaveMaker applications run in a standard Java server based on Tomcat, the Dojo Toolkit, Spring and Hibernate. Currently, it is supported on Linux, Mac and Windows. WaveMaker has also released a cloud computing version of its 4GL that runs on Amazon EC2.
As an example of the level of complexity of applications that can be built using a WYSIWYG development approach for Ajax applications, the WaveMaker Studio was built using WaveMaker. WaveMaker is meant for use by web developers who prefer visual tools.
