        public class createFsaxml 
        {
        Element elcct = null;
        Element elpt = null;
        ResultSet rs = null;
        Document doc = null;
        PrintWriter pw = null;
        Element rootelem = null;

        public createFsaxml(){

        
        try{
        // register driver

        DriverManager.registerDriver(new

        Statement stmt = c.createStatement();

        ResultSet rs = stmt.executeQuery("Select * from GMISFAF1");

        createxml();    
        c.close();
             } catch(SQLException e){
                                System.out.println(e);
                                                     }
        }       



        public void createxml(){


        Document doc = new Document();

        Element rootelem = new Element("FSArootElement");

        doc.setRootElement(rootelem);

        
        try{
        
        PrintWriter pw = new PrintWriter(new BufferedWriter(new
FileWriter("/java/demo/fsa.xml")));

        while (rs.next()){
        Element elcct = new Element("CurrencyCodeType");
        elcct.addContent(rs.getString(12).trim());
//
        Element elpt = new Element("PriceType");
        elpt.addContent(rs.getString(13).trim());
//
                         }
//
        rootelem.addContent(elcct);
        rootelem.addContent(elpt);
//

        XMLOutputter outputter = new XMLOutputter();
        outputter.output(rootelem, pw);
        pw.flush();
        pw.close();
        }catch(IOException e){
                System.out.println(e);

        catch(SQLException e){
                System.out.println(e);
        }       
        
        }



        public static void main(String[] args){

        String sfile = args[0];

        String spath = args[1];

        if (args.length != 2){

        // report errors

        System.out.println("Error! ");
        System.out.println("Pls enter location of the schema");
        return;
        }
        createFsaxml cxml = new createFsaxml();

        System.exit(1);

        }
