Just for completeness, here's the smaple code i've been given:

import java.util.HashMap;
import java.util.Iterator;
import java.util.Collection;
import java.util.Map;

import java.io.StringWriter;
import java.io.StringReader;

import org.exolab.castor.mapping.Mapping;

import java.io.IOException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.OutputStreamWriter;

import org.xml.sax.InputSource;

import java.util.HashMap;

public class HashTest {

    public static void main(String[] args) {

        Root root = new Root();

        HashMap map = new HashMap();
        map.put("key1", "value1");
        map.put("key2", "value2");

        root.setChildren(map);

        testRoot(root);
        Mapping      mapping = new Mapping();

        try {
            // 1. Load the mapping information from the file
            mapping.loadMapping( "mapping.xml" );

            FileWriter writer = new FileWriter("test.xml");
            // 4. marshal the data with and print the XML in the console
            Marshaller marshaller = new Marshaller(writer);
            marshaller.setMapping(mapping);
            marshaller.marshal(root);
            writer.close();

            FileReader reader = new FileReader("test.xml");
            // 2. Unmarshal the data
            Unmarshaller unmar = new Unmarshaller(mapping);
            Root newRoot = (Root)unmar.unmarshal(reader);

testRoot(newRoot);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static void testRoot(Root root) {
        Map kids = root.getChildren();
        for (Iterator itr = kids.keySet().iterator(); itr.hasNext();)
        {
            Object key = itr.next();
            System.out.println("Here is a key [" + key.toString() +
                "] value [" + kids.get(key) + "]");
        }

    }
}

and

import java.util.Map;
import java.util.HashMap;

public class Root {

HashMap _children = new HashMap();

public HashMap getChildren() {
    System.out.println("#getChildren!");
      return _children;
}
public void setChildren(HashMap m) {
    System.out.println("#setChildren!");
      _children = (HashMap)m;
}
}
