RestyGWT is a GWT generator for REST services and JSON encoded data transfer objects. RestyGWT Rest Services allow you to define an asynchronous service API which is then implemented via GWT deferred binding by RestyGWT. It features generation of asynchronous RESTful JSON based service proxies, encoding and decoding of Java objects to JSON, and an easy-to-use REST API.
Reverspring is a Java library that allows you to create Spring IoC XML files from POJO at runtime. CoI stands for Control of Inversion: Reverspring just inverts the inversion of control mechanism of Spring Framework, allowing you to (re)write Spring descriptors starting from your Java objects. With Reverspring, you can write process descriptors on XML files without reinventing a new DTD or XML schema, but just using the well known Spring IoC syntax.
Rivet CGI allows Rivet applications to run as a CGI, either automatically (i.e., no modifications to the applications themselves from "mod_rivet") from Apache, as a standalone CGI under any Web server, or as a standalone HTTP server itself. It can be used to build Web applications that can be distributed and executed as a single file in either CGI or Standalone HTTP mode.
Rome is a set of Atom/RSS Java utilities that make it easy to work in Java with most syndication formats. It accepts all current flavors of RSS (0.90, 0.91, 0.92, 0.93, 0.94, 1.0, and 2.0) and Atom 0.3 feeds. Rome includes a set of parsers and generators for the various flavors of feeds, as well as converters to convert from one format to another. The parsers can give you back Java objects that are either specific for the format you want to work with, or a generic normalized SyndFeed object that lets you work on with the data without bothering about the underlying format.
