JAX-WS Handlers

As an alternative to the @HandlerChain annotation, JAX-WS Handlers can be added to both your client or server via application.properties:

application.properties

# A web service endpoint with multiple Handler classes
quarkus.cxf.endpoint."/greeting-service".handlers=org.acme.MySOAPHandler,org.acme.AnotherSOAPHandler

# A web service client with a single Handler
quarkus.cxf.client."greeting-client".handlers=org.acme.MySOAPHandler

Where MySOAPHandler could look like below:

import jakarta.xml.ws.handler.soap.SOAPHandler;
import jakarta.xml.ws.handler.soap.SOAPMessageContext;

public class MySOAPHandler implements SOAPHandler<SOAPMessageContext> {

    public boolean handleMessage(SOAPMessageContext messageContext) {
        SOAPMessage msg = messageContext.getMessage();
        return true;
    }
    // other methods
}

Class loading

The SOAPHandler classes are loaded via CDI first..

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