Kesha Williams explains the three main requirements for a JAX-WS endpoint.
- [Narrator] A simple POJO…can be turned into a soap based web service endpoint…by adding the @WebService annotation to the class.…The approach of starting with the pojo…is also called the code first approach,…which doesn't use a WSDL to generate the Java code.…Remember, WSDL stands for web services description language…and is used for describing the functionality offered…by a web service.…When starting with the WSDL,…the approach is called the Contract First Approach…the @WebService annotation…causes all public methods of the class…to be exposed as web service operations.…
This type of endpoint is considered…to be a surface endpoint interface…and declares the methods…that a client can invoke on the service.…There are several attributes…for the @WebService annotation.…I'm using the endpoint interface…because my implementation includes the use of an interface…and interface isn't a firm requirement,…but I'm using one in the implementation,…so end point interface is used to explicitly identify…the interface.…I'm also using the service name attribute,…
