[Wong Ho Kan]

hello everyone,

I would like to know how to code a Complex object properly for load a
multi primary key object from database.

for example, the mapping.xml for that object is "MarketData"
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
<class name="MarketData" identity="securityCode date time">
    <description>MarketData</description>
    <map-to table="tbl_marketdata" />
    <field name="securityCode" type="java.lang.String" >
      <sql name="md_securitycode" type="varchar"/>
    </field>
    <field name="date" type="long" >
      <sql name="md_date" type="integer"/>
    </field>
    <field name="time" type="long" >
      <sql name="md_time" type="integer"/>
    </field>
    ......
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

how load that MarketData from database and the MarketData bean is
already implemented Timestampable interface. but still failed to load
that object from database.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
MarketData data = getMarketData();
Database db = BasicDAO.getDatabase();
db.begin();
db.load(MarketData.class, new Complex(), data);  // how to load??
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
