Purview is a simple, lightweight, easily extensible validation API using Java 5 annotations. It provides full support for internationalization (i18n) and interpolation of dynamic values from validation messages using pluggable expression engines. Purview is NOT a JSR 303 implementation and ... [More] provides several features that JSR 303 does not including: * Lots of already written validators. * Full support for i18n with dynamic interpolation * Rich typing of validation problems instead of simple booleans * Not just for JavaBeans: Full support for validating ALL java language constructs including fields, classes, methods, and method parameters. * Optional strict mode [Less]

Ferret is a class path scanning API for the Java platform. Unlike previous class path scanning APIs, Ferret does not restrict scanning to only certain types or force developers to learn a complicated and constricting query language. Instead, Ferret applies the Visitor pattern to allow developers to ... [More] quickly develop powerful filters that can scan for anything (e.g. properties files, xml, images, video, etc). Ferret even allows developers to modify files (including Java class files) on the fly. It can also scan for files and classes across the network. The fact that Ferret is lightweight, dynamic, fast and easy to use is just icing on the cake. ;-) [Less]

Jetpack is an API for marshalling and unmarhalling to JSON data. With a JAR file less than 13K, Jetpack is not only the world's fastest and most flexible JSON API, it is also the most lightweight. Jetpack also includes features that many other JSON APIs do not, such as: * A five second learning ... [More] curve. It's really simple!!! * Support for streaming JSON as well as creating JSON data in space * Flexible mechanisms that allow the developer to control what is JSON data and what is not. * 100% Unit test coverage * 100% Pure Java (No Native Code) * 100% Self-contained (No external dependencies) * Universal character set support * Well under 1K effective lines of code * A flat heap foot print. Jetpack can stream terabytes of data to JSON without even blinking. [Less]
