Hi I use: java: 13 Spring Boot 2.2.2
org.apache.cxf:cxf-spring-boot-starter-jaxws:3.3.4 org.apache.cxf:cxf-rt-features-clustering:3.3.4 My CXF client is defined as a Spring bean: @Bean public MyService createMyServiceClient(JaxWsProxyFactoryBean jaxWsProxyFactoryBean) { MyService service = (MyService) jaxWsProxyFactoryBean.create(); Client client = ClientProxy.getClient(service); client.getBus().getOutInterceptors().add(new HeaderInterceptor()); return service; } elsewhere I have it injected and use it like this: @Autowired private MyService myService; private void aMethod() { Client client = ClientProxy.getClient(myService); client.getRequestContext().put("messageId", messageId); myService.myMethod(); } I need to put the messageId into the request context so that the HeaderInterceptor can put the value into the http request header. Everything works just great, now I'd like to use Spring Cloud Config so that I could change the url of the remote server on the fly. In order to use this feature I needed to add @RefreshScope to my bean definition which creates a proxy object. With this configuration I receive this exception: java.lang.ClassCastException: class org.springframework.aop.framework.JdkDynamicAopProxy cannot be cast to class org.apache.cxf.frontend.ClientProxy When my code tries to get the client in order to set the message id, it fails. If I remove this bit, everything just works and I can change the url without restart but the messageId is missing from the http header which unfortunatelly is not optional. Any idea ? Thanks in advance Gabor
