SOAP is a message format for exchanging messages with a server. WSDL is a language for describing web or network services. We’ve learned about WSDL files and how they’re related to SOAP. See this example in a Camel app on GitHub Wrapping up If you want to see this WSDL used in an Apache Camel (Java) application, then check out the file here: Which can be used to add or retrieve books from a collection. Definition for a web service called BookService, GetAllBooks - retrieves all books from the collection GetBook - gets information about a single book from the collection The service exposes three synchronous (input/output) operations: Here is an example WSDL file which describes an imaginary web service called BookService. Next, let’s take a look at an example WSDL file. īoomerang, an extension for Google Chrome for testing SOAP services.Postman, another desktop application for testing web services SoapUI, an open source desktop application for testing web services You can also use a desktop program to parse a WSDL and interact with the web service it describes.

In Python, you can use Zeep, which is a library that can parse a WSDL file, and generate code so you can call the remote web service. If you don’t want to configure CXF yourself, you can use an integration framework like Apache Camel, which indirectly uses CXF. CXF can read WSDL files and interact with SOAP services. In Java, you can use any library which implements the JAX-WS standard, like Apache CXF. Instead, you use a library for your programming language, like one of these: You can use a WSDL to create code that calls a web service.īut usually, you don’t write code yourself to read and parse a WSDL file.

It’s basically a manual or recipe that describes a web service. It’s a contract, which can be understood by machines. How do you use a WSDL file?Ī WSDL file is designed for computers to understand. Defines the physical location of the service (e.g. Defines exactly how each operation will take place over the network (we use SOAP, in the example below). Defines each operation in the web service, and the messages associated with each operation. Defines the messages that can be exchanged with the web service. Structure of a WSDL fileĪ WSDL document is written in XML and contains the following elements: Advertisements Element What it does Defines the data types (XML elements) that are used by the web service. So WSDL defines the operations and messages for a web service, and SOAP defines the concrete format for sending those messages to a server. Ī way to enhance messages with other features, like encryption.Ī way to return fault or error messages from the service.The messages themselves – an Envelope containing a Header and a Body The messages that you can exchange with a service

SOAP sits on top of an existing transport, like HTTP. SOAP is a standard for exchanging messages with a server, or making a remote procedure call (RPC). You’ve probably seen the term WSDL alongside SOAP.

MIME binding How is WSDL related to SOAP? This is where you give a concrete definition of how the service will be accessed, and what data format it will use. WSDL doesn’t insist that a service must have a certain message format, or must be accessed using a certain network protocol. WSDL isn’t often chosen for new web services anymore, but many legacy systems still use it.Ī valid WSDL file contains all the information you need to send a request to a web service. It’s an XML format, which defines the operations in a web service, its the messages used by each operation, and their XML elements, or data types. Web Services Description Language (WSDL) is a standard for describing web services.

One day you might be lucky enough to work with WSDL. WSDL has been around for a long time, but this old granddaddy of web services ain’t disappearing, just yet.
