You might want to give XStream a shot  it is not complicated  It basically does the heavy lifting

You can use Xembly  a small open source library that makes this XML creating process much more intuitive   String xml   new Xembler    new Directives        add  root        add  order        attr  id    553        set   140 00     xml      Xembly is a wrapper around native Java DOM  and is a very lightweight library

I liked the Xembly syntax  but it is not a statically typed API  You can get this with XMLBeam      Declare a projection public interface Projection         XBWrite   root order  id       Projection setID int id         XBWrite   root order       Projection setValue String value      public static void main String   args           create a projector     XBProjector projector   new XBProjector            use it to create a projection instance     Projection projection   projector projectEmptyDocument Projection class           You get a fluent API  with java types in parameters      projection setID 553  setValue   140 00            Use the projector again to do IO stuff or create an XML-string     projector toXMLString projection       My experience is that this works great even when the XML gets more complicated  You can just decouple the XML structure from your java code structure

You can use a DOM XML parser to create an XML file using Java  A good  example can be found on this site   try       DocumentBuilderFactory docFactory   DocumentBuilderFactory newInstance        DocumentBuilder docBuilder   docFactory newDocumentBuilder           root elements     Document doc   docBuilder newDocument         Element rootElement   doc createElement  company        doc appendChild rootElement          staff elements     Element staff   doc createElement  Staff        rootElement appendChild staff          set attribute to staff element     Attr attr   doc createAttribute  id        attr setValue  1        staff setAttributeNode attr          shorten way       staff setAttribute  id    1           firstname elements     Element firstname   doc createElement  firstname        firstname appendChild doc createTextNode  yong         staff appendChild firstname          lastname elements     Element lastname   doc createElement  lastname        lastname appendChild doc createTextNode  mook kim         staff appendChild lastname          nickname elements     Element nickname   doc createElement  nickname        nickname appendChild doc createTextNode  mkyong         staff appendChild nickname          salary elements     Element salary   doc createElement  salary        salary appendChild doc createTextNode  100000         staff appendChild salary          write the content into xml file     TransformerFactory transformerFactory    TransformerFactory newInstance        Transformer transformer   transformerFactory newTransformer        DOMSource source   new DOMSource doc        StreamResult result    new StreamResult new File  C   testing xml         transformer transform source  result        System out println  Done      catch ParserConfigurationException pce       pce printStackTrace     catch TransformerException tfe       tfe printStackTrace

Have look at dom4j or jdom  Both libraries allow creating a Document and allow printing the document as xml  Both are widly used  pretty easy to use and you ll find a lot of examples and snippets   dom4j - Quick start guide
