XINS is a technology used to define, create, and invoke remote APIs. XINS is specification-oriented. When API specifications are written (in XML), XINS will transform them to HTML-based documentation and Java code for both the client-side and the server-side. The communication is based on HTTP. XINS competes with the complex SOAP technology. Main design goals include simplicity, scalability, and testability. XINS is not only a specification technology, but also an application development framework. It offers transaction logging, unique log documentation, and active code generation.
python-fedex is light wrapper for Fedex's Web Services SOAP API. The intent is to stay out of the way of the developer as much as possible, while handling some of the more repetitive and mundane portions of forming and sending SOAP requests. The module makes use of the excellent suds package along with Python versions 2.5 and up, but not yet Py3K.
Moose is a framework for getting XML into and out of Java software. It integrates easily with Spring, Spring Web Services, or plain Java applications. It will generate an XML schema which describes your mapping configuration. Spring Web Services can wrap Moose's schema generator, creating a nice stack for simple, rapid development of SOAP Web services in Java.
Ripcord is an PHP 5 XML-RPC server and client library with a very simple and easy to use API. You can create XML-RPC, (simplified) SOAP 1.1, and SimpleRPC clients with one call and then call RPC methods as if they were local methods of the client. You can create a server with one call, passing it any number of objects or classes whose methods it will publish and automatically document.
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.).
