JAX-WS Providers

JAX-WS Providers are fully supported, and can be implemented as shown below.

Given the following sample Provider implementation:

import jakarta.xml.transform.stream.StreamSource;
import jakarta.xml.ws.BindingType;
import jakarta.xml.ws.Provider;
import jakarta.xml.ws.Service;
import jakarta.xml.ws.ServiceMode;
import jakarta.xml.ws.WebServiceProvider;
import java.io.StringReader;

@WebServiceProvider
@ServiceMode(value = Service.Mode.PAYLOAD)
public class StreamSourcePayloadProvider implements Provider<StreamSource> {

    public StreamSourcePayloadProvider() {
    }

    public StreamSource invoke(StreamSource request) {
        String payload = StaxUtils.toString(request);

        // Do some interesting things ...

        StreamSource response = new StreamSource(new StringReader(payload));
        return response;
    }
}

The application.properties can be configured as shown below.

# A web service endpoint with the Provider implementation class
quarkus.cxf.endpoint."/stream-source".implementor=org.acme.StreamSourcePayloadProvider

Class loading

Provider classes are loaded via CDI first..

If no CDI beans are available, the constructor without parameters will be invoked to instantiate each class.
