Kesha Williams explains SOAP Services, XML, and JAX-WS.
- [Instructor] SOAP stands for Simple Object Access Protocol…and is a messaging protocol that uses XML…to allow applications running on different systems…and platforms to communicate.…SOAP messages are complex.…The data being shared is placed…in what's called an envelope.…The envelope has a specific structure.…Rules for encoding, invocations, and responses…are often transmitted over HTTP.…Java API for XML web services,…shortened as JAX-WS, is a framework…that simplifies using SOAP…by hiding the complexities of SOAP…and provides a simple API for developing…and deploying web services.…
JAX-WS is a part of standard Java.…How does JAX-WS work?…A service class is exposed as a web service endpoint.…Step one, the JAX-WS runtime will publish…the web service and its functionality using a WSDL,…which stands for Web Services Description Language…and is used for describing the functionality…offered by a web service.…Step two, a proxy to the service is generated,…which allows a calling client to invoke the service.…
Step three, API calls are converted to SOAP messages…
