Java Error. HELP NEEDED URGENTLY

["Anand, Rajesh" <Rajesh_Anand@xxxxxx>]

        Folks,
        
        This is the copy of the source that I ran on AS400.

        One thing I know for sure is that it gives error on the
highlighted statement below....

        import java.io.*;
        import java.sql.*;
        import java.text.*;
        import java.util.*;

        import org.jdom.output.*;
        import org.jdom.input.*;
        import org.jdom.*;
        import org.jdom.transform.*;
        import org.jdom.contrib.input.*;
        import com.ibm.as400.access.*;

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

        

        public createFsaxml() throws Exception{

        
        try{
        // register driver

        DriverManager.registerDriver(new
com.ibm.as400.access.AS400JDBCDriver());
                 
        Connection c =
DriverManager.getConnection("jdbc:as400://mldev400/SPANAND");

        System.out.println("Got connection.. processing");

        Statement stmt = c.createStatement();

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

        System.out.println("Got Query results");
        System.out.println("Trying to create XML file");

        createxml();    

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



        public void createxml() throws Exception{

        int cntr = 0;

        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());
        cntr++;
//
                         }
//
        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);
        }       
        System.out.println("total no of records: " +
String.valueOf(cntr));
        
}


        //public ValidateDoc(File f){

        //private String f;

        //try{ 

        //    }
        //}

        public static void main(String[] args) throws Exception{

//      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();

//Validate val = new ValidateDoc(File cxml);

//      System.exit(1);

}
}

        The Error is....

        java.lang.NullPointerException 

        Thanks for your help in advance.

        regards,
