If you work on a team offering data or services to clients, you'll likely need to build web services. The most widely adopted technologies for Java-based web services are SOAP and REST, as they allow standardized, scalable, and language-independent external application communication. Use this course shows to learn how to build a web service that adopts the SOAP protocol. Use Maven to create a web service project and the JAX-WS library to build a web service class and a method that remote client applications can invoke. Then, deploy this service to a URL endpoint where clients can access it. Next, explore the automatically generated JAX-WS artifacts, including the WSDL file. Then, use the WSDL file to build a client application and interact with the server-side web service. Bu the end of this course, you'll be able to build SOAP-based web services using JAX-WS and Maven.
