I post my code once again:
HelperContext hc = HelperProvider.getDefaultContext();
PersonFactory.INSTANCE.register(hc);
DAS das = DAS.FACTORY.createDAS(getConfig(configFile));
Command readPerson = das.getCommand("getFirstPerson");
DataObject root = readPerson.executeQuery();
Person p = PersonFactory.INSTANCE.createPerson();
p = (Person)root.getDataObject("Person[1]");
The exception is:
java.lang.ClassCastException:
org.apache.tuscany.sdo.impl.DynamicDataObjectImpl cannot be cast to
sdo.Person

Could you please supply some detail of the exception.
I note that in some of the postings above the schema seems to have a
type of "erson" - Similarly there are element names of "ame", "ge" and
"d" - is this what you have or just a cut and paste error?

I'm guessing your exception is a ClassCastException because the actual
class is AnyTypeDataObjectImpl, and not PersonImpl. For the DAS to
create instances of your generated class it would a) have to be using
the default helper context, and b), understand that Person objects are
from the http://www.example.org/person namespace. Perhaps someone who
is familiar with DAS could take a look at this?

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=.0" encoding="UTF-8"?>
<schema xmlns=ttp://www.w3.org/2001/XMLSchema"
targetNamespace=ttp://www.example.org/person"
xmlns:tns=ttp://www.example.org/person" elementFormDefault="qualified">
<complexType name=erson">
<sequence>
<element name=ame" type="string"></element>
<element name=ge" type="int"></element>
<element name=d" type="int"></element>
</sequence>
</complexType>
</schema>
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=ERSON" typeName="Person">
<Column columnName=D" primaryKey="true"/>
</Table>
<Command name=etFirstPerson" SQL="select * from PERSON where ID=1"
kind=elect"/>
3) I do:
HelperContext hc = HelperProvider.getDefaultContext();
PersonFactory.INSTANCE.register(hc);
DAS das =AS.FACTORY.createDAS(getConfig(configFile));
Command getPerson =as.getCommand("getFirstPerson");
DataObject root =etPerson.executeQuery();
DataObject p1 =root.getDataObject("Person[1]");
Person p2 =ersonFactory.INSTANCE.createPerson();
p2 =Person) p1; // Here I have exception
Can somebody help me to solve this problem?

Actually I did the same thing from this example:
http://tuscany.apache.org/workingwithstaticdataobjects.html
Just
SDOUtil.registerStaticTypes(CustomerFactory.class);
was changed with
HelperContext hc = HelperProvider.getDefaultContext();
PersonFactory.INSTANCE.register(hc);
But unfortunately it's not working.
