jWic is a java-based development framework for developing dynamic web applications with the convenience and familiarity of 'rich client' style programming. The component-based, event-driven programming model makes it easy for developers to quickly create flexible and robust web applications with built-in Ajax functionality. With the 3.1.0 release of the jWic-Framework, there are a number of powerful new controls in the jWic Ecolib sub project for the jWic user. It includes a new TableViewer control with column sorting, resizing, paging, selection options and many other features people already know from rich-client programming techniques is added. It also supports tree-like expand/collapse mechanism with the possibility to display a categorized list or a simple tree. Along with this release comes a new tool called the jWic SourceViewer. This tool allows homepage visitors to sneak into the sources of a project or a particular project. It can display more than only the "Java-Files". It can used to view images, templates, configuration files and many others. So the visitor, who is browsing the sample code of a project without downloading it, gets the whole picture of a project while just visiting the homepage. The SourceViewer is available for free under the Apache License 2.0. We believe that it could be useful for many projects that want to offer their visitors a quick view into their (sample) sources. Any feedback about this tool is appreciated. Check out the new samples, which demonstrates the new controls, and the SourceViewer on the project homepage at http://www.jwic.de/
