Use JAXB  http   www mkyong com java jaxb-hello-world-example   package com mkyong core   import javax xml bind annotation XmlAttribute  import javax xml bind annotation XmlElement  import javax xml bind annotation XmlRootElement    XmlRootElement public class Customer        String name      int age      int id       public String getName             return name              XmlElement     public void setName String name            this name   name             public int getAge             return age              XmlElement     public void setAge int age            this age   age             public int getId             return id              XmlAttribute     public void setId int id            this id   id               package com mkyong core   import java io File  import javax xml bind JAXBContext  import javax xml bind JAXBException  import javax xml bind Marshaller   public class JAXBExample       public static void main String   args           Customer customer   new Customer          customer setId 100         customer setName  mkyong          customer setAge 29          try            File file   new File  C   file xml            JAXBContext jaxbContext   JAXBContext newInstance Customer class           Marshaller jaxbMarshaller   jaxbContext createMarshaller                output pretty printed         jaxbMarshaller setProperty Marshaller JAXB FORMATTED OUTPUT  true            jaxbMarshaller marshal customer  file           jaxbMarshaller marshal customer  System out            catch  JAXBException e            e printStackTrace

There is no need for any External libraries  the JRE System libraries provide all you need   I am infering that you have a org w3c dom Document object you would like to write to a file  To do that  you use a javax xml transform Transformer   import org w3c dom Document import javax xml transform Transformer  import javax xml transform TransformerFactory  import javax xml transform TransformerException  import javax xml transform TransformerConfigurationException  import javax xml transform dom DOMSource   import javax xml transform stream StreamResult    public class XMLWriter       public static void writeDocumentToFile Document document  File file                Make a transformer factory to create the Transformer         TransformerFactory tFactory   TransformerFactory newInstance                Make the Transformer         Transformer transformer   tFactory newTransformer                Mark the document as a DOM  XML  source         DOMSource source   new DOMSource document               Say where we want the XML to go         StreamResult result   new StreamResult file               Write the XML to file         transformer transform source  result             Source  http   docs oracle com javaee 1 4 tutorial doc JAXPXSLT4 html

You can use the JDOM library in Java  Define your tags as Element objects  document your elements with Document Class  and build your xml file with SAXBuilder  Try this example     Root Element Element root new Element  CONFIGURATION    Document doc new Document      Element 1 Element child1 new Element  BROWSER      Element 1 Content child1 addContent  chrome      Element 2 Element child2 new Element  BASE      Element 2 Content child2 addContent  http fut      Element 3 Element child3 new Element  EMPLOYEE      Element 3 -- gt  In this case this element has another element with Content child3 addContent new Element  EMP NAME   addContent  Anhorn  Irene        Add it in the root Element root addContent child1   root addContent child2   root addContent child3     Define root element like root doc setRootElement root     Create the XML XMLOutputter outter new XMLOutputter    outter setFormat Format getPrettyFormat     outter output doc  new FileWriter new File  myxml xml
