Sub: Java API CreateObject Error

I get an error for following code. Object is hr.attendance. Can some one please guide me?

public static void main(String[] args) throws MalformedURLException, XmlRpcException {

    // TODO code application logic here

    Session openERPSession;

    openERPSession = new Session("localhost", 8069, "Demo", "admin", "demo");


    try {

           // startSession logs into the server and keeps the userid of the logged in user

           openERPSession.startSession();

           ObjectAdapter partnerAd = openERPSession.getObjectAdapter("hr.attendance");

            ////// 

            ////// Example code snippet goes here

            //////


            Object[] ids = new Object[] {0,1,2,3,4,5};
            RowCollection partners = partnerAd.readObject(ids, new String[]{"action","action_desc", "day", "employee_id", "sheet_id"});

            for (Row row : partners){
                 System.out.println("Row ID: " + row.getID()+"Action:" + row.get("action")+" day" + row.get("day")+" EmpName" + ((Object[])row.get("employee_id"))[1].toString()+" EmpId" + ((Object[])row.get("employee_id"))[0].toString()+"/ "+row.get("employee_id"));

            }

            Row newPartner = partnerAd.getNewRow(new String[]{"action", "day", "employee_id"});
            newPartner.put("action", "sign_out");
            newPartner.put("day", "2013-07-03");
            newPartner.put("employee_id", new Object[] {"2","Fabien Pinckaers"});
            partnerAd.createObject(newPartner);

            System.out.println("New Row ID: " + newPartner.getID());

} catch (Exception e) { System.out.println("Error while reading data from server:\n\n" + e.getMessage()); }

}

}
