Spring-Integration-DSL & Soap Service Soap header is not getting invoked - spring

Question

I am trying to call a soap service with spring integration DSL, have some custom header that needs to be added.
Constructed marshellingoutboundgateway. Trying to override DefaultSoapHeaderMapper but none of the overridden methods are getting called.
Trying to construct some thing like this.
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
<ObjectType34 >
</ObjectType34>
</soapenv:Header>
<soapenv:Body>
<ObjectType12 >
</ObjectType12>
</soapenv:Body>
</soapenv:Envelope>
There is a sample in : https://github.com/spring-projects/spring-integration/blob/master/src/reference/asciidoc/ws.adoc
looks like only available in 5.0
posted detail code.
Any insights will be helpful.
#Configuration
#SpringBootApplication
#IntegrationComponentScan
#EnableIntegration
public class Application {
public static void main(String[] args) {
ConfigurableApplicationContext ctx = SpringApplication.run(Application.class, args);
Info Info = ctx.getBean(Info.class);
//Constructing request Payload
ObjectType12 getInfoType = new ObjectFactory().ObjectType12();
JAXBElement<GetInfoType> getInfoTypeJAXBElement = new ObjectFactory().createGetInfo(getInfoType);
JAXBElement<GetInfoResponseType> getInfoResponseType = Info.getInfo(getInfoTypeJAXBElement);
System.out.println(getInfoResponseType.getName());
ctx.close();
}

gateway.setHeaderMapper(new DefaultSoapHeaderMapper() {

super.populateUserDefinedHeader("Content-Type", "application/soap+xml", target);
}
#Override

super.populateStandardHeaders(headers, target);
}
#Override
public void fromHeadersToRequest(MessageHeaders headers, SoapMessage target) {
SaajSoapMessage targetMessage = (SaajSoapMessage) target;
SoapHeader header = targetMessage.getEnvelope().getHeader();
//Constructing SOAP Header
JAXBElement<ObjectType34> trackingHdrTypeJAXBElement = ObjectFactory().createHdr(ObjectType34);
jaxb2Marshaller().marshal(trackingHdrTypeJAXBElement, header.getResult());
System.out.println(header.getResult());
}
#Override
public void setRequestHeaderNames(String... requestHeaderNames) {
super.setRequestHeaderNames("*");
}
});
gateway.setMessageFactory(new SaajSoapMessageFactory() {
#Override
public void setSoapVersion(SoapVersion version) {
super.setSoapVersion(SoapVersion.SOAP_11);
}
});
return gateway;
}
}

UPDATE: Modified the code
#Bean
public DefaultSoapHeaderMapper headerMapper11() {
return new DefaultSoapHeaderMapper() {
#Override
public void fromHeadersToRequest(MessageHeaders headers, SoapMessage target) {
SaajSoapMessage targetMessage = (SaajSoapMessage) target;
SoapHeader header = targetMessage.getEnvelope().getHeader();
//Constructing SOAP Header
JAXBElement<ObjectType34> trackingHdrTypeJAXBElement = ObjectFactory().createHdr(ObjectType34);
jaxb2Marshaller().marshal(trackingHdrTypeJAXBElement, header.getResult());
super.fromHeadersToRequest(headers, target);
}
};
}
and set the header using the method call:
gateway.setHeaderMapper(headerMapper11());
Now the overridden method is getting called and having the header as well.
Code is working as expected now.
