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.
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.).
Azzyzt JEE Tools is a set of Eclipse plugins for creating a so-called "azzyzted" project, and for creating code from a model. Azzyzt uses Java JPA entities as a model, and from that model it creates an enterprise application, ready to be deployed in a Java EE 6 application server like GlassFish 3.1, ready to be accessed via CORBA, SOAP, and REST. Thus the generated application is a set of Web services, providing all that you need in a typical CRUD application. Generated enterprise applications have separate source folders for generated and developer-supplied content. You can add your own functionality to a well-engineered base project. Azzyzt JEE Tools is not about user interfaces. It is expected that the generated application is accessed by a RIA frontend or by a fat client.
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.
