Pass data from a SOAP handler to a webservice server Class

Question

I have a Spring boot SOAP services with cxf, and my Consumers are passing me SSO token in http header.. I am able to retrieve the SSO token using JAX-WS handler. I am saving that SSO token into handler class level variable, and after control going through various classes it reaches to a point where I have to make a request to another service and have to pass the same SSO token, but in my Connection class the SSO token value is NULL.

@Component
public class EndPointHandler implements SOAPHandler<SOAPMessageContext> {
    private List<String> ssoToken;
    private Map<String, List<String>> headers;

    @Override
    public boolean handleMessage(SOAPMessageContext context) {
        Boolean isResponse = (Boolean) context.get(SOAPMessageContext.MESSAGE_OUTBOUND_PROPERTY);
        if (!isResponse) {
            headers = ((Map<String, List<String>>) context.get(MessageContext.HTTP_REQUEST_HEADERS));
            if (headers != null) {
                if (!headers.get("SSOToken").get(0).isEmpty()) {
                    List<String> ssoToken = headers.get("SSOToken");
                    LOGGER.info(ssoToken.get(0));
                    this.ssoToken = ssoToken;
                } else {
                    LOGGER.error("SSO Token value cannot be empty");
                    return false;
                }
            }
        }
        return true;
    }

    public void setSSOToken() {
        headers.put("SSOToken", this.ssoToken);
    }
}

In my Connection class I have to set this SSO token as a header and make a call to another service but SSO token value is NULL.

Connection Class:

@Component
public class ConnectionManager {
    private static final Logger LOGGER = LoggerFactory.getLogger(ConnectionManager.class);

    @Autowired
    private EndPointHandler handler;

    private void establishConnection(String uri) throws FileNetIntegrationException {
        handler.ssoToken; //  --> I need SSO token here but the value is NULL;
    }
}

This is how I set the handler chain in my WebServiceConfig class:

@Bean
public Endpoint endpoint(Bus bus) {
    EndpointImpl endpoint = new EndpointImpl(bus, changeServiceEndpoint);
    WebService ws = AnnotationUtils.findAnnotation(endpoint.getImplementorClass(), WebService.class);
    endpoint.setAddress("/" + ws.serviceName());
    endpoint.publish();
    SOAPBinding binding = (SOAPBinding) endpoint.getBinding();
    ArrayList<Handler> handlerChain = new ArrayList<>();
    handlerChain.add(new EndPointHandler());
    binding.setHandlerChain(handlerChain);
    return endpoint;
}

I think, I got a solution right after posting the last piece of code here when I noticed that I used new EndPointHandler() while adding it into handler chain.. I tried using Autowired it and it worked for me.
