Using Apache's XmlRpcClient (http://ws.apache.org/xmlrpc/) it should 
work like this:


    public static void main(String[] args) throws IOException, 
XmlRpcException {
        XmlRpcClient  xmlRpcClient = new 
XmlRpcClient("http://myogoserver:8050/RPC2";);

        xmlRpcClient.setBasicAuthentication("root", "ogo");

        Hashtable fetchSpec = new Hashtable();
        String qualifier = "name = 'root'";
        fetchSpec.put("qualifier", qualifier);
        Vector sortOrdering = new Vector();
        sortOrdering.add("name");
        fetchSpec.put("sortOrdering", sortOrdering);

        Vector params = new Vector();
        params.add(fetchSpec);
        Object result = xmlRpcClient.execute("person.fetch", params);

        System.out.println("Result class: " + result.getClass());
        System.out.println("Result: " + result);
    }

The output should look like this:

Result class: class java.util.Vector
Result: [{isAccount=true, url=, name=root, 
id=skyrix://myogoserver/Sx_hampton/300750, phones={02_tel={type=02_tel, 
number=, info=, telephoneId=300810}, 03_tel_funk={type=03_tel_funk, 
number=, info=, telephoneId=300820}, 10_fax={type=10_fax, number=, 
info=, telephoneId=300840}, 15_fax_private={type=15_fax_private, 
number=, info=, telephoneId=300850}, 01_tel={type=01_tel, number=, 
info=, telephoneId=300800}, 05_tel_private={type=05_tel_private, 
number=, info=, telephoneId=300830}}, owner={}, phoneTypes=[01_tel, 
02_tel, 03_tel_funk, 05_tel_private, 10_fax, 15_fax_private], 
number=SKY300750, addresses={location={type=location, 
id=skyrix://myogoserver/Sx_hampton/300790}, private={type=private, 
id=skyrix://myogoserver/Sx_hampton/300770}, mailing={type=mailing, 
id=skyrix://myogoserver/Sx_hampton/300780}}, isPrivate=false, 
extendedKeys=[email1, email2, email3, job_title, other_title1, 
other_title2], login=root, extendedAttrs={}, objectVersion=2, 
isComplete=true}]

Apache's XmlRpcClient wants a list of parameters encoded in a 
java.util.Vector even if you only one parameter. The person.fetch 
XMLRPC needs a FetchSpecification as a 'struct' which is represented in 
Apache's XmlRpcClient as a java.util.Hashtable (see: 
http://ws.apache.org/xmlrpc/types.html). There you have to put a 
qualifier (String) and optional a sortordering.

If you use "name like 's*'" as qualifier you'll get all persons with a 
name starting with s sorted by name.

Hope this helps.
