Generating SOAP Requests from Java objects - soap

Question

I need to create a Soap request from a request object in Java. What is needed is below :
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<tem:tag1>
<tem:tag2>
<MyDataSet>
<!-- more elements within-->
</MyDataSet>
<tem:tag1>
<tem:tag2>
</SOAP-ENV:Body>
<atom/>
</SOAP-ENV:Envelope>
However, what I am getting is this :
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<MyDataSet>
<!-- more elements within-->
</MyDataSet>
</SOAP-ENV:Body>
<atom/>
</SOAP-ENV:Envelope>
Can someone please tell me how do I add <tem:tag1> and <tem:tag2> in the soap request ? This is the code that I have written so far:
public static void main(String[] args) throws Exception
{
MyRequest request = new MyRequest();
Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
Marshaller marshaller = JAXBContext.newInstance(MyRequest.class).createMarshaller();
marshaller.marshal(request, document);
SOAPMessage soapMessage = MessageFactory.newInstance().createMessage();
soapMessage.getSOAPPart().getEnvelope().addNamespaceDeclaration("tem", "http://tempuri.org/");
soapMessage.getSOAPBody().addDocument(document);
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
soapMessage.writeTo(outputStream);
String output = new String(outputStream.toByteArray());
System.out.println(output);
}

Assuming that the web service has published WSDL, I suggest that instead of rolling your own client code, you generate it using wsimport, a utility that is included in the Java JDK. One article on how to use it can be found here.
