MessageContext of Webservice during Java Callout action

Question

Hello! I have a web service that accepts username in parameters and appends ws-security headers according to username parameter.
@HandlerChain(file = "handler-chain.xml")
@WebService(portName = "SecuritySignerPort", serviceName = "SecuritySignerWS", targetNamespace = "http://ru.a3.a3tv/")
public class SignerImpl {
@Resource
private WebServiceContext context;
@WebMethod(operationName = "addWsSecHeader")
public void addWsSecHeader(@WebParam(name = "username") String username) {
     MessageContext ctx = context.getMessageContext();
     ctx.put("username", username);
     return;
public class CustomSOAPHandler implements SOAPHandler<SOAPMessageContext> {
@Override
public boolean handleMessage(SOAPMessageContext context) {
     Boolean outbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
     if (!outbound) {/       
return true;
     SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
     SOAPHeader header = envelope.getHeader();
     SOAPElement security =
          header.addChildElement("Security", "wsse", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");
     SOAPElement usernameToken =
          security.addChildElement("UsernameToken", "wsse");
     usernameToken.addAttribute(new QName("xmlns:wsu"), "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd");
     SOAPElement username =
          usernameToken.addChildElement("Username", "wsse");
     username.addTextNode((String) context.get("username"));+
     return true;
Service works fine if i run it outside OSB. But if i invoke it via service callout action context.get("username") is always Null. Please help me. Thanks in advance.

It doesn't matter what the client of your web service is. Just compare the request message that works for you with the request message sent by OSB.
