NoClassDefFoundError on org/apache/cxf/jaxb/JAXBToStringStyle

Question

Good day,

I am using apache cxf and spring boot to build a web service but when I try to call the endpoint, it gives me this error:

    WARN 15936 --- [nio-8080-exec-4] o.a.cxf.phase.PhaseInterceptorChain      : Application {
endpointMethod has thrown exception, unwinding now

        org.apache.cxf.interceptor.Fault: org/apache/cxf/jaxb/JAXBToStringStyle
                [...]
                at java.lang.Thread.run(Thread.java:748) [na:1.8.0_144]
        Caused by: java.lang.NoClassDefFoundError: org/apache/cxf/jaxb/JAXBToStringStyle

Here is my configuration for the webservice:

@Configuration
public class WebServiceConfig {

@Bean
public org.springframework.boot.web.servlet.ServletRegistrationBean cxfServlet() {
    return new org.springframework.boot.web.servlet.ServletRegistrationBean(new CXFServlet(), "/cxf-api/*");
}

@Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
    return new SpringBus();
}


@Bean
public Conc2MGPService conc2MGPService() {
    return new RegistrationServiceEndpoint();
}

@Bean
public Endpoint endpoint() {
    EndpointImpl endpoint = new EndpointImpl(springBus(), concessionario2MGPService());
    endpoint.publish("/registration_endpoint");
    return endpoint;
}

and here my POM:

            </plugin>
        </plugins>
    </build>
</project>

What am I missing? What I am doing here is a simple log on the object passed on the request.

@Override
    public RegisterContract(RegisterContractRequest registerContractRequest) {
        log.info("RegisterContract" + registerContractRequest);
        return null;
    }

I think that something is missing in my POM but I can't figure out what.

Answer 1

Add this dependency to your pom.

 <dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-bundle</artifactId>
    <version>2.7.18</version>
</dependency>

As a side note this jar is deprecated, try to update your dependencies. New version of the above jar is like below. ( But in order to use it, you have update your related dependencies)

<groupId>org.apache.cxf.xjc-utils</groupId>
<artifactId>cxf-xjc-runtime</artifactId>
<version>3.2.1</version>
