I am writing a program to store stuff to xml using the storeToXML method
but I can;t get it to compile here it is; any ideas?

import java.io.*;

import java.util.*;

public class XmlWrite {

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

        try {

            Properties props = new Properties();

            props.setProperty("something", "bla");

            props.setProperty("stuff", "brown and black");

            props.setProperty("morestuff", "me");

            props.setProperty("enablepassword", "yes");

            props.setProperty("answer", "null");

            String OperatingSystem = System.getProperty("user.home") +"\\";

            FileOutputStream xmlwrite =
            new FileOutputStream(OperatingSystem + "config.xml");

            props.java.util.Properties.storeToXML(xmlwrite, "config");

            xmlwrite.close();
        }

        // if writing to the specified output stream results in an
IOException

        catch (IOException e) {

            //Print system error

            System.err.println("An Error Occured While Writing To The
File");
        }

        //  if os is null.

        catch (NullPointerException e) {

            //Print system error

            System.err.println("OS Value is Null");

        }

    }

}
