WSDL (Web Service Description Language) is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint . Generally consuming a WSDL (Webservice Description Language) in Outsystems is an easy task but it might get trickier when the WSDL has unsupported use cases built into it. This article will help to understand the difficulties associated with such unsupported use case and attempts to provide a solution. Here is the list of unsupported SOAP use cases from Outystems: https://success.outsystems.com/Documentation/11/Extensibility_and_Integration/SOAP/Consuming_SOAP_Web_Services/Unsupporte d_SOAP_Use_Cases#list-attribute-in-a-single-list-attribute Workday WSDL: The following link provides the WWS (Workday Web Services) API Documentation f...

Typescript language is a wrapper around javascript language. Any javascript code can also be a typescript code, but typescript has additional features like Strong Typing, Object Oriented features, Catching errors during compile time.

There are various tools and dependencies which are available in Spring Starter project which are very useful in creating better spring based microservice architectures for developing mobile or web applications. Here is one such commonly used tools if you are using the springboot microservice architecture in designing your applications. Spring Cloud Config Server : This dependency is used for externalizing the configuration properties in various microservices present in your organization. The main advantage of using Spring Cloud Config Server is that you can get away from deploying or restarting your services if there is only configuration change made in your microservice. Generally, if you change any property in your microservice, you will have to restart the microservice to see that change. But if you configure your properties in the Spring Cloud Config Server, the changes will be affected automatically in the applications. Steps to activate this dependency: ·   ...
