CRest (Client REST) is a lightweight library that simplifies the integration of third party RESTful services into Java applications. CRest is mainly annotation-driven, allowing the developer to focus on the essential aspects of the integration of a REST service, such as the definition of the Java interface that maps the remote REST methods and the data model the interface will deal with. The rest is achieved by annotating a plain Java interface with the relevant information such as the service end-point, the desired timeouts, URL formats, etc. CRest will handle everything else, including HTTP request generation, auto marshalling of the response, and more.
Huxley is a set of classes that makes it trivial to produce legitimate output for queries made by the prevailing standard of REST queries. Instead of writing a network API with many methods, being run over RPC, you instead write only a couple of methods that are accessed by HTTP GET requests. You then return the results (in either XML, JSON, or text) for processing. XML and JSON are chosen because of the ease by which they can be parsed by most languages. In this way, you open up the scope of your network services to many more people than would otherwise have access to it.
SerfJ provides a very easy way of developing Java REST Web applications. It helps you to develop your application over an elegant MVC architecture, giving more importance to convention than configuration. This means, for example, you will not need configuration files or annotations in order to specify which view serves a controller's method. However, SerfJ is very flexible, so if you want to jump over those conventions, you can configure the behavior of your applications as you like. The framework tries to meet the JSR 311 specification, but it doesn't follow every point of the specification, because the purpose is to have a very intuitive library, and some some aspects of the specification are out of the scope of SerfJ.
Google Custom Search is a class that performs searches against a Google Custom Search engine, processing the response (search results and/or spelling suggestions) into properties of the object. It uses either cURL or the HTTP stream wrapper, depending on what is available on the server. The user can also specify the character encoding for the search query. Results are also made available in that encoding.
Fulworx is a REST framework that uses simple annotations of XWork "Action" implementations to expose restful interfaces. Similar to Struts, Fulworx sits as a controller on top of Restlet. Each action is attached as a resource using Restlets. Standard resources are represented by default as XML (or JSON) using JAXB, but any representation may be specified. Actions may be used in other frameworks such as Struts and Webwork, since they're just XWork implementations.
The UniversalContainer class is an attempt to provide a class which can act in a manner similar to the untyped variables, arrays, and hash-maps found in popular scripting languages such as Perl and PHP. The result is a class that can hold a wide variety of data and meta-data in a very flexible structure. UniversalContainers can hold integers, doubles, booleans, single characters, strings, and wide character strings. UniversalContainers may also be used as associative maps between strings and other UniversalContainers, or as arrays of UniversalContainers. Routines for database access and REST programming are included, including a JSON serialization engine.
