Hi Dihiansan, The code which you given is superb,and it is working fine. But i need to send the xml headers generated out of your code needs to send as a SOap headers  so i need to know how can i send that. Also your code contains static methods which is fine but in HCI to put i need to have only non-static methods, so i have changed my code as per your code reference . So kindly help me in setting the SOAP Headers in java. Thanks and Regards, Vijay

Commenting these out in your code

//

SoapHeader soapHeader = new SoapHeader(new QName(Envelope.getNamespaceURI(),Envelope.getLocalName()), Envelope); 


//

soapHeader.setMustUnderstand(true); 


//

List headersList = new ArrayList(); 


//

List headerList = new ArrayList();


//

headerList.add(xmlString); 




//System.out.println("Headers List is " +headerList); 


//

System.out.println(headerList); 

Already produces a SOAP Header without any values. If you want to set values, use the setTextContext method e.g adding this line

Would already set a value for majorNumber
