Zato is an Enterprise Service Bus (ESB) and app server written by pragmatists for pragmatists. It provides an HA load-balancer, hot-deployment, and hot-reconfiguration almost everywhere (forget server restarts). It has a browser-based GUI, CLI, and API (forget XML configuration). It supports many protocols, industry standards, and data formats, including HTTP, JSON, SOAP, REST, AMQP, JMS WebSphere MQ, ZeroMQ, Redis, SQL, and FTP.
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.
WSF Staff is Web Service Framework for C++, AJAX, and J2ME that is based on Apache Axis2/C. WSF Staff wraps Apache Axis2/C code into C++, and also provides many additional features: a stateful Web services implementation in C++ with instance support, a synchronous and asynchronous client implementation in C++, AJAX, and J2ME, a service-component architecture implementation, support for RESTful Web services and clients, WSDL support with xsd import and export, J2ME client support (based on ksoap), a flexible and extensible code generator to generate any sort of Web service related source code (not only in C++), security support (users, groups, sessions, ACLs, etc.), and a Web application toolkit (webapp) with widget support.
RestPose is a search engine. It is designed to take a set of documents and then, when given a query, to return ranked lists of documents which are a good match for that query. RestPose manages a set of internal indexes and provides an interface (over HTTP, in a fairly RESTful style, using JSON as the main transfer format) which allows documents to be submitted and removed from indexes, and which allows searches to be performed.
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.
RoboZombie allows easy integration with remote services by allowing you to replicate an endpoint contract and generate a proxy to access it. Contracts can be very flexible in terms of the resources they access. These could be vary from static HTML content or an RRS feed, to a RESTful web service endpoint. Each endpoint contract is specified on a single interface using annotations to provide the communication metadata. It is then wired into your code via an annotation, where it is created, cached, and injected at runtime.
