Request-response family

SOAP REST
HTTP, SMTP, JMS, … HTTP only
Single URL per service Resources identified by URLs
POST only
operation encoded in the message		 HTTP methods have special meaning
XML only Typically JSON

WSDL: strict contract OpenAPI

SOAP today

Still crucial in

finance, travel, healthcare, government services, etc.

SOAP on Quarkus

The community had to self-organize:

  • One guy created a PoC
  • Another improved it
  • Another gave feedback from using it in production (!)

^ Not enough to support it as a RH product

Test coverage, documentation, productization

Build time class generation & wiring

@WebService(serviceName = "HelloService")
public class HelloServiceImpl implements HelloService {

    @WebMethod
    public String hello(String greeting, String person) {
        return greeting + " " + person + "!";
    }

}

Configuration

quarkus.cxf.client.myCalculator.wsdl = http://localhost:8082/calculator-ws/CalculatorService?wsdl
quarkus.cxf.client.myCalculator.client-endpoint-url = http://localhost:8082/calculator-ws/CalculatorService
quarkus.cxf.client.myCalculator.service-interface = com.acme.calculator.CalculatorService

Client beans

@ApplicationScoped
public class MyBean {
    @CXFClient("myCalculator")
    CalculatorService calculator;
    ...
    int result = calculator.add(2, 3);
}
