TagEventor is a project to enable radically simple computer usage by creating physical-object-based user interfaces. It does this using commercially available (and relatively cheap), standardized RFID technology in the form of small, simple USB connected contacted card/tag readers and small, cheap tags. The project was started based on products available from the "touchatag" company, which has clients for Windows and Mac, and run their own Web service to enable many interesting Web-based applications. However, no simple, lightweight Linux client was available, and the Web focus meant that some client-focused functionality was not possible. The software is currently a daemon that monitors the presence of one or more RFID tags on a connected reader and generates "system events" when tags are placed on it or removed from it.
JCatapult is a development platform written in Java. Built for modularization, JCatapult allows developers to build modules such as a blog, content-management system, wiki, or any other reusable set of features and use them across multiple applications. Built on top of open source technologies, JCatapult is a robust and scalable platform. However, it is also agile and lightweight because it uses a convention over configuration approach.
SlimWeb aims to replace Struts or JSF in your J2EE application, but is closer to Rails or TurboGears in its heavy use of convention-over-configuration, simplicity, and power. It aims to reduce (and most of the time completely eliminate) all boilerplate code, XML configuration files, and even deployment times.
Jaiwls is a component oriented framework with bundled a servlet Web server (Jetty) and HTML widget library. It is easy to integrate in existing applications with static compiled Java classes and supports dynamic websites using Groovy, a runtime injectable singelton instance, well formatted stack traces, a low memory footprint for compiled projects, powerful URL rewrites possible, a production mode (with no recompilation) for Groovy-based applications, and much more.
Simple Log is a small library that does logging very simply and requires you to do almost nothing (other than actually logging) to get log output to happen. It is much simpler to use than a logging framework, especially in terms of configuration. It doesn't attempt to solve every logging problem in one package, but contains enough features to be a viable alternative for most applications that need logging. This tool will handle the logging needs of most small- to large-sized projects, but with an almost non-existent learning curve.
OpenLaszlo Schema Generator provides methods to enhance LZX-Markup from the OpenLaszlo RIA with full schema/namespace support and validation. You can run it from the command line or from inside your project using ANT. The JAR contains tasks to generate an XSD from your project LZX files; by doing that, you have full Schema Validation in Eclipse, and it will show you all your XML schema errors. The validation is aware of ALL tags and attributes: the LZX base components (+incubator) and your project specific code. Further, you get content-sensitive drop down menus for Tags and Attributes.
