REST APIs access a resource for data (a URI); SOAP APIs perform an operation. An API is designed to expose certain aspects of an application’s business logic on a server, and SOAP uses a service interface to do this while REST uses URIs. In SOA 12c additional feature provided for REST, REST bindings introduced which helps to create REST enable service and reference components. Note: The REST interfaces and BPEL component support end-to-end JSON. Not only does Oracle introduce the REST Adapter, but JSON support is also added in SOA Suite 12c. Service-oriented architecture (SOA) is an approach used to create an architecture based upon the use of services. Services (such as RESTful Web services) carry out some small function, such as producing data, validating a customer, or providing simple analytical services.
Publish or consume application data and logic from anywhere, to anywhere, on any platform using REST service APIs.
Includes all of the programming with web services concepts and architecture.
Exposing a RESTful service will be described in a later blog. These features will greatly increase the integration options and flexibility of Oracle SOA Suite. However, if you are using other service components, like the Mediator, you need to use the 12.1.3–style composite that internally maps REST resources and verbs to WSDL operations and XML schemas, and translates the incoming payload into XML.
Component Reuse: Once an organization built an application component, and offered it as a service, the rest of the organization can utilize that service.
In addition to using HTTP for simplicity, REST offers a number of other benefits over SOAP:
Click here to see how to create Restful service is SOA 11g. This video shows developers how to create a JSON/REST API to access existing SOA-based resources using drag-and-drop tools. Plus, it entered the scene as a way to access web services in a much simpler way than possible with SOAP by using HTTP. REST is an architectural style. The REST Web Service approach is an approach for using REST purely as a communication technology to build SOA. In this blog I’ll describe how a RESTful service can be called by using the REST adapter. For quite a while, we've all heard the buzz surrounding a "service-oriented architecture" (SOA).
Due to not having special file for definition, like WSDL, it is a manually job using the endpoint. In this post, we are going to cover What is REST in SOA 12c and Steps to Create REST in SOA 12c which is one of the new features in SOA 12c.For those who are new, REST stands for Representational State Transfer.
