Hello to all!

How can I map a DataObject to a Java object? My situation is:

1) From person.xsd was generated Person.java, PersonFactory.java, 
PersonImpl.java and PersonFactory.java. XSD2JavaGenerator was used for it.

Here is person.xsd:

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema" 
xmlns:tns="http://www.example.org/person" elementFormDefault="qualified">

    <complexType name="Person">
            <element name="Name" type="string"></element>
            <element name="Age" type="int"></element>
            <element name="id" type="int"></element>

2) I have a RDB with a table PERSON and columns ID:integer, 
NAME:varchar, AGE:integer.

Here is a part from Config.xml:

    <Table tableName="PERSON" typeName="Person">
        <Column columnName="ID" primaryKey="true"/>

    <Command name="getFirstPerson" SQL="select * from PERSON where ID=1" 

3) I do:

        HelperContext hc = HelperProvider.getDefaultContext();

        DAS das = DAS.FACTORY.createDAS(getConfig(configFile));

        Command getPerson = das.getCommand("getFirstPerson");
        DataObject root = getPerson.executeQuery();

        DataObject p1 =  root.getDataObject("Person[1]");

        Person p2 = PersonFactory.INSTANCE.createPerson();

        p2 = (Person) p1; // Here I have exception

Can somebody help me to solve this problem?

Best regards,
