No adapter for endpoint Spring WS SOAP

Question

I have a very strange problem. I'm trying send request to my SOAP-app, and I get this logs (logging-level=trace):

2022-06-18 12:08:33.341 DEBUG 11612 --- [nio-8080-exec-1] yloadRootAnnotationMethodEndpointMapping : Looking up endpoint for [{localhost/soap}GetAllUser]

It turns out that the server finds the endpoint, but does not find the adapter? So, i written this:

    @Autowired
    List<EndpointAdapter> adapters;

    @PostConstruct
    public void a () {
        log.info("ADAPTERS:");
        adapters.forEach(System.out::println);
    }

And get this output:

2022-06-18 12:07:03.106  INFO 11612 --- [           main] c.d.u.endpoint.UserEndpoint              : ADAPTERS:
org.springframework.ws.server.endpoint.adapter.DefaultMethodEndpointAdapter@1f6f0fe2
org.springframework.ws.server.endpoint.adapter.PayloadEndpointAdapter@ab2009f

My XSD file contains this:

    <xs:element name="GetAllUserRequest">
        <xs:complexType>
            <xs:sequence>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="GetAllUserResponse">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="users" type="tns:UserWithoutRole" minOccurs="0" maxOccurs="unbounded"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

Generated classes look like this:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(
    name = ""
)
@XmlRootElement(
    name = "GetAllUserRequest"
)
public class GetAllUserRequest {
    public GetAllUserRequest() {
    }
}

My request:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
                  xmlns:gs="localhost/soap">
    <soapenv:Header/>
    <soapenv:Body>
        <gs:GetAllUser/>
    </soapenv:Body>
</soapenv:Envelope>

Endpoint class:

@Endpoint
@Slf4j
public class UserEndpoint {
    private static final String NAMESPACE_URI = "localhost/soap";

    private UserService userService;

    @Autowired
    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    @Autowired
    List<EndpointAdapter> adapters;

    @PostConstruct
    public void a () {
        log.info("ADAPTERS:");
        adapters.forEach(System.out::println);
    }

    @PayloadRoot(localPart = "GetAllUser", namespace = NAMESPACE_URI)
    @ResponsePayload
    public GetAllUserResponse getAllUsers(@RequestPayload GetAllUserRequest request) {
        log.info("GET ALL USERS");

        GetAllUserResponse response = new GetAllUserResponse();
        response.getUsers().addAll(userService.findAll());

        return response;
    }
}

WebServiceConfig:

@EnableWs
@Configuration
public class WebServiceConfig extends WsConfigurerAdapter {
    @Bean
    public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
        MessageDispatcherServlet servlet = new MessageDispatcherServlet();
        servlet.setApplicationContext(applicationContext);
        servlet.setTransformWsdlLocations(true);
        return new ServletRegistrationBean(servlet, "/ws/*");
    }

    @Bean(name = "soap")
    public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema countriesSchema) {
        DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
        wsdl11Definition.setPortTypeName("SoapPort");
        wsdl11Definition.setLocationUri("/ws");
        wsdl11Definition.setTargetNamespace("localhost/soap");
        wsdl11Definition.setSchema(countriesSchema);
        return wsdl11Definition;
    }

    @Bean
    public XsdSchema countriesSchema() {
        return new SimpleXsdSchema(new ClassPathResource("userServiceSOAP.xsd"));
    }

    @Bean
    public EndpointAdapter messageEndpointAdapter() {
        return new PayloadEndpointAdapter();
    }
}

Why does none of the adapters support my endpoint? Thanks!

I faced the same issue. In my case it was related to using Jakarta XML bind. When I change it to Javax instead of Jakarta everything works fine. So when you check imports in your generated sources, it should be smth like that:

import javax.xml.bind.annotation.XmlRootElement;

Additional dependencies for Java 8+ listed below:

<!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.1</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/javax.activation/activation -->
    <dependency>
        <groupId>javax.activation</groupId>
        <artifactId>activation</artifactId>
        <version>1.1</version>
    </dependency>

    <!-- https://mvnrepository.com/artifact/org.glassfish.jaxb/jaxb-runtime -->
    <dependency>
        <groupId>org.glassfish.jaxb</groupId>
        <artifactId>jaxb-runtime</artifactId>
        <version>2.3.1</version>
    </dependency>

Note if your Java version is 8 or less, this guide works fine w/o changes, because Java 8 is still shipped with JAXB implementation.

I saw that Spring 5 doesn't support Jakarta, they planned to add support in future 6 version.
