This is so that when the client application calls the relevant port type, it will then be able to access the operations which are bound to this port type. Port types are just like interfaces.
So if a client application needs to use a web service they need to use the binding information to ensure that they can connect to the interface provided by that web service. Initially, when a client application makes a call to the web service, it will do by calling the name of the web service. A web service is an important component in building modern day web applications.
Their main purpose is to allow multiple applications built on various programming languages to talk to each other. For instance, we can have a. Net web application talks to a Java application via a Web service. The reason that it is in XML is so that the file can be read by any programming language.
So if the client application was written in. Net, it would understand the XML file. Similarly, if the client application was written in the Java programming language then also it would be able to interpret the WSDL file. The WSDL file is what binds everything together. From the above diagram, you can see that you can create a web service in the.
Net language. So this is where the service gets implemented. Asked 6 years, 2 months ago. Active 6 years, 2 months ago. Viewed 2k times. Why do we need the WSDL file? Improve this question.

Many questions, I guess you ask out of curiosity so I try to answer them "just" top-down and hopefully there are some hints that help you orient further: Can't the server determine which method to use and which response to send only by parsing the SOAP request?
Why do we need portType [ Improve this answer. I'm new to SOAP. I mean the client object has convertSpeed and we can use it as a normal, IDE suggestion enabled method. Viewed 2k times.

For example, consider the following web method signatures, from methods in two different web services:. The preceding example is taken from a WSDL for a web service that uses a class that contains the following property:. The isc:property attribute allows the property names to be the same in the generated client classes as in the service classes.
