<soap:header/> block in not coming in soap response

Question

I am writing a soap web service with apache-cxf. I am following code first approach. The issue is , i am not getting "soap:header" tag under in response.I have gone through other wsdl and java implementation classes and not able to find what needs to be added in wsdl or SEI to get soap:header block in response.Please let me know if any one can help me in this.I would share more details if required.

My webservice class looks like -

    import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.ParameterStyle;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;

/**

 */
@WebService(targetNamespace = "http://webservice.sample.com", name = "SampleWebService")
@XmlSeeAlso({ObjectFactory.class})

public interface SampleWebService {

    @WebResult(name = "Response", targetNamespace = "" )
    @RequestWrapper(localName = "requestWrapper", targetNamespace = "http://webservice.sample.com", className = "com.sample")
    @WebMethod
    @ResponseWrapper(localName = "responseWrapper", targetNamespace = "http://webservice.sample.com", className = "com.sample" )
    public com.sample.Response requestWrapper(
        @WebParam(name = "request", targetNamespace = "http://requests.webservice.sample.com")
        com.sample.Request request
    );
}

Soap Request -

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://webservice.sample.com" xmlns:ord="http://requests.webservice.sample.com">
   <soapenv:Header/>
   <soapenv:Body>
      <web:requestWrapper>
         <ord:Request>
            <ord:Name>Harry</ord:Name>
            <ord:CreationDate>2015-09-09T12:45:00</ord:CreationDate>                  
         </ord:Request>
      </web:requestWrapper>
   </soapenv:Body>
</soapenv:Envelope>

Expected Response -

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header/>
<soap:Body>
<ns2:responseWrapper xmlns:ns2="http://common.sample.com" xmlns="http://response.sample.com">
<ID>12345678910</ID>
</ns2:responseWrapper>
 </soap:Body>
</soap:Envelope>

Actual Response -

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ns2:responseWrapper xmlns:ns2="http://common.sample.com" xmlns="http://response.sample.com">
<ID>12345678910</ID>
</ns2:responseWrapper>
 </soap:Body>
</soap:Envelope>

Answer 1

An empty header element is not required. If you want to add a header, add for example the method parameter

@WebParam(partName = "bankHeader", mode = WebParam.Mode.OUT, name = "bankRequestHeader", targetNamespace = "http://example.bank.skjolber.github.com/v1", header = true)
        javax.xml.ws.Holder<BankRequestHeader> bankHeader

(The sample was generated by moving and input to output header in this sample .)
