NanoHttpd is a lightweight HTTP server designed for embedding in other applications. It's only one Java file, in two "flavors", one strictly Java 1.1 compatible, and one at "current" standards. It supports GET, POST, PUT, HEAD and DELETE requests, and supports file uploading with very small memory overhead. Temp file usage and the threading model are easily customized.
]project-open[ is a Web-based enterprise project management application with a focus on finance and collaboration. Its main purpose is to coordinate the work of project managers, project members, and stake holders across multiple projects. Target organizations are companies or corporate departments that need to track finances, tasks, and resources for a large number of concurrently running projects. ]project-open[ consists of about 200 modules for resource management, time sheet management, HR, CRM, ITSM, collaboration, and financials. It is built on top of OpenACS.org, an open-source Web platform featuring role-based permissions, workflows, dynamically extensible objects, and full-text search.
PSX is a framework for developing dynamic Web sites in PHP. The goal of PSX is to help you develop RESTful APIs serving Web standard formats like JSON, XML, Atom, and RSS. It has a focus on social technologies and provides classes to use and implement OAuth, OpenID, Opengraph, Opensocial, Opensearch, PubSubHubbub, Atom, and RSS.
SOAP/REST Mock Service is a simple configurable framework to mock out SOAP or RESTful (or "REST-like") Web services. Its main goal is to support automated integration testing of applications that integrate with 3rd party Web services. Functionality and usage scenarios of the mock service are in a way analogous to unit testing mocking tools (like Mockito or EasyMock). Once properly configured, SOAP/REST Mock Service exposes Web service mocks that can be called from application code and controlled via a REST interface from integration test code (setup, verify, etc.).
Resty is a small, convenient API to talk to RESTful services from Java. Its focus is on simplicity and ease-of-use, often requiring only two lines of code to access RESTful Web services. It lets you use much less code than URLConnection, it's simpler than Apache HTTP client, and it's more reliable than Jersey client.
