‘Output Arguments’ allow us to enter a parameter name into which we want the response to be saved. We can enter the input value directly or choose to select it from a parameter file. For this operation, there is only one input required – Currency. ‘Input Arguments’ allow us to enter the data input required for this operation. ‘Custom SOAP Header’ allows us to enter the custom headers if any (do not enter anything for now). ‘Transport Layer Configuration’ allows us to specify transport options (leave it to the default options). Let’s select ‘GetCultureInfo’ operation here. On the ‘New Web Service Call’ window, we can see fields like ‘Service’, ‘Port Name’ and ‘Operation’. Now go to the ‘SOA Tools’ menu again and select ‘Add Service Call’.

Make sure the WSDL is imported successfully. Select URL (or File) and click on ‘Import’. On the ‘Manage Services’ window, click on ‘Import’ (to import a new service). Go to the ‘SOA Tools’ menu and select ‘Manage Services’. So let’s start by creating a new (blank) VuGen script with ‘Web Services’ protocol. This will be the corresponding WSDL link. This service provides the following operations (In general, a Web service can provide multiple operations):įor Example, we can invoke the ‘GetCultureInfo’ operation and see the response. WSDL (Web Services Description Language) is an XML-based file that gives details like what the web service does along with the information required to access the web service.įor our Example script, we will use a currency converter Web Service. There is one more thing that we need to understand – WSDL. Now let’s see how to do SOAP Web service scripting using VuGen.Īs already discussed, SOAP is an XML based protocol (it uses XML to send and receive messages). It permits multiple data formats like JSON, Text, XML etc. It’s getting popular because of its lightweight nature (consumes less bandwidth and resource in its implementation). REST: REST stands for Representational State Transfer and is an architectural style for developing web services.

As it is XML based, it is platform and language independent.

SOAP: SOAP stands for Simple Object Access Protocol and is an XML based industry standard protocol for designing and developing web services.

The underlying principle behind the successful implementation of Web Services is the standard way of integration and communication (between applications) using open standards. There are many services that are readily available and one can call and use in his/her application.įor Example, if we want a payment gateway in our application, we need not build one – we can use (may need to pay) the services of any of the already established payment gateway providers. In this modern era, a software system need not be built from scratch.
