Basically you need to use SAAJ API, this is an API that use SOAPMessage and give you some objects and methods to create SOAP request programatically, you shouls see this link for further reference. Also review the documentation from Oracle, they give you some useful examples. For real example you could check this link

MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage soapMessage = messageFactory.createMessage();

// Retrieve different parts
SOAPPart soapPart = soapMessage.getSOAPPart();
SOAPEnvelope soapEnvelope = soapMessage.getSOAPPart().getEnvelope();

// Two ways to extract headers
SOAPHeader soapHeader = soapEnvelope.getHeader();
soapHeader = soapMessage.getSOAPHeader();

// Two ways to extract body
SOAPBody soapBody = soapEnvelope.getBody();
soapBody = soapMessage.getSOAPBody();

// To add some element
SOAPFactory soapFactory = SOAPFactory.newInstance();
Name bodyName  = soapFactory.createName("getEmployeeDetails","ns1","urn:MySoapServices");
SOAPBodyElement purchaseLineItems = soapBody.addBodyElement(bodyName);
Name childName = soapFactory.createName("param1");
SOAPElement order = purchaseLineItems.addChildElement(childName);
order.addTextNode("1016577");
