How to return different type of objects in quarkus-cxf

[uugan]

I need to return different types of objects, these object are implemented from interface but cxf does not support it.
for example:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {"defaultMessage", "customMessage", "code"})
@XmlRootElement(name = "PaypointsSoapFault")
public class PaypointsSoapFault  implements ISubtract{
...
}
// -----------------------------------------------------------------------------------------------
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="", propOrder = {"newBalance"})
@XmlRootElement(name = "SubtractResponse ")
public class SubtractResponse implements ISubtract{
...
}

and webservice function looks like below:

@WebService(serviceName = "TestService")
public class TestServiceImpl implements TestService {
    @Inject
    MainUtil mainutil;
    @Override
    public ISubtract subtractPoints(String uid, long points) {
         ISubtract subtractResp = null;
        try {
            subtractResp = mainutil.subPoints(uid, points); // here if error occurred it should return PaypointsSoapFault, otherwise SubtractResponse 
            
        } catch (Exception ex) {
            logger.error("", ex);
        }
        return subtractResp;
    }

How to do this?

Hi @uugan Perhaps this may be helpful for you...

Hi @uugan I'm not sure if you had a chance to explore the link shared previously, pls see the attached quarkus-cxf-interface.zip project that uses a HelloResponse interface as the @WebService return type.

The crux of the implementation is depicted below ...

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

    @Inject
    HelloUtil helloUtil;

    @WebMethod
    @Override
    public HelloResponse hello(String name) {
        return helloUtil.hello(name);
    }

}

Where HelloResponse is an interface with two implementations, HelloResponseQuarkusImpl and HelloResponseSimpleImpl.

@XmlTransient
@XmlSeeAlso({HelloResponseQuarkusImpl.class, HelloResponseSimpleImpl.class})
public interface HelloResponse {
    
}

You can invoke the service with something like below, each invocation should alternate between the HelloResponse implementations.

curl -v -X POST -H "Content-Type: text/xml;charset=UTF-8" \
    -d \
      '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
        <soap:Body><ns2:hello xmlns:ns2="http://acme.org/"><arg0>Shumon</arg0></ns2:hello></soap:Body>
       </soap:Envelope>' \
    http://localhost:8080/soap/hello

Keep us posted if you still have any issues.

Hi @shumonsharif I tried that code, but it gives that first object as second object with its parameters.

@XmlTransient
@XmlSeeAlso({SubtractPointsResponse.class,   PaypointsSoapFault.class})
public interface ISubtract{
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="SubtractPointsResponse")
public class SubtractPointsResponse implements ISubtract{
...
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name="PaypointsSoapFault", propOrder = {"defaultMessage", "customMessage", "code"})
public class PaypointsSoapFault implements  ISubtract{
...
}

mainUtil

        if (0 != outmsg) {
            return new PaypointsSoapFault("service error", outmsg, 1);
        }
        else {
            return  new SubtractPointsResponse(num);
        }

But when call it, response looks like:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <pay:SubtractPointsResponse xmlns:pay="http://******">
         <pay:return xsi:type="pay:PaypointsSoapFault" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <pay:defaultMessage>service error</pay:defaultMessage>
            <pay:customMessage>not found.</pay:customMessage>
            <pay:code>1</pay:code>
         </pay:return>
      </pay:SubtractPointsResponse>
   </soap:Body>
</soap:Envelope>

But i need response like below:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
      <pay:PaypointsSoapFault xmlns:pay="http://*******">
         <pay:defaultMessage>service error</pay:defaultMessage>
         <pay:customMessage>not found.</pay:customMessage>
         <pay:code>1</pay:code>
      </pay:PaypointsSoapFault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Hi @uugan Pls feel free to attach a reproducer that demonstrates what you're experiencing (you can update the sample project I provided earlier)!
