Open Source AJAX Enabled Framework for Building Customized User Interfaces for JMX

The first release of ajax4jmx has been announced. Ajax4Jmx is claimed to be the first open source AJAX enabled framework for building customized user interfaces for JMX.

This is a framework for building customized dynamic web interfaces for JMX applications. Java Management Extensions (JMX) technology provides the tools for building distributed, Web-based, modular and dynamic solutions for managing and monitoring devices, applications, and service-driven networks. By design, this standard is suitable for adapting legacy systems, implementing new management and monitoring solutions, and plugging into those of the future. ajax4jmx currently provides a simple JMX browser, as well as JMX components for use in other applications.

It is implemented using GWT, Google's Widget Toolkit.

It includes general purpose widgets such as dynamic editable tables supporting multiple selection. It also includes dynamic charts. Here’s a bit of technical information pertaining to ajax4jmx alpha-1.0, for developers.
