// Send the message 
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();

// Get the response
SOAPMessage responseMessage = connection.call(requestMessage, endpoint);

// Extracts a DOM Document and sets the first child of this SOAPBody as it's document element
Document responseDocument = responseBody.extractContentAsDocument();
...

// Finally
connection.close();
