What is the difference between abstract and concrete WSDL?

An abstract WSDL document defines: the operations provided by the web service. The input, output and fault messages used by each operation to communicate with the web service, and their format. A concrete WSDL document adds the information about how the web service communicates and where you can reach it.

Which WSDL element connects the abstract and concrete sections of a WSDL?

A WSDL document can be divided into “abstract” and “concrete” portions that by convention often are defined in two or more files (where the concrete file imports the abstract one). The abstract elements are , , and (or in 2.0); the concrete ones are and .

Where is concrete WSDL used?

If a WSDL has all the sections – including the concrete parts such as Bindings & Service then it is referred to as a concrete WSDL. This WSDL defnition can be used to connect to the actual service since it has the protocol and service endpoint information.

What does an abstract WSDL file contains?

Abstract WSDL contains two main components: The operations that form the interface definition. The data types of the input, output, and fault parameters of the operations.

Why we use abstract WSDL in MDS?

Utilizing abstract WSDLs and MDS will provide compile time isolation from other services that may or may not be deployed. An abstract WSDL is a standard WSDL that doesn’t contain the endpoint implementation details. The abstract WSDL for a SOA process can be found in the base composite directory.

What is a concrete WSDL?

● A concrete WSDL document adds the information about how the web service communicates and where you can reach it. A concrete WSDL document contains the abstract WSDL definitions, and also defines: the communication protocols and data encodings used by the web service.

What is difference between soap and rest?

SOAP stands for Simple Object Access Protocol whereas REST stands for Representational State Transfer. SOAP is a protocol whereas REST is an architectural pattern. Comparing SOAP vs REST API, SOAP only works with XML formats whereas REST work with plain text, XML, HTML and JSON.

What is abstract WSDL?

● An abstract WSDL document describes what the web service does, but not how it does it or how to contact it. An abstract WSDL document defines: the operations provided by the web service. the input, output and fault messages used by each operation to communicate with the web service, and their format.

Which is an abstract element in a WSDL document?

A WSDL document can be divided into “abstract” and “concrete” portions that by convention often are defined in two or more files (where the concrete file imports the abstract one). The abstract elements are , , and (or in 2.0); the concrete ones are and .

What’s the difference between an abstract message and a concrete message?

I am learning about WSDL from online documentation and came across definitions about abstract message and concrete message: Message definitions are always considered to be an abstract definition of the message content. A message binding describes how the abstract content is mapped into a concrete format.

How are endpoints and messages defined in WSDL?

In WSDL, the abstract definition of endpoints and messages is separated from their concrete network deployment or data format bindings. This allows the reuse of abstract definitions: messages, which are abstract descriptions of the data being exchanged, and port types which are abstract collections of operations.

What do you need to know about WSDL structure?

Binding – a concrete protocol and data format specification for a particular port type. Port – a single endpoint defined as a combination of a binding and a network address. Service – a collection of related endpoints. Describes the operations that can be performed and the messages involved. Sample XML WSDL Document.
