SDO Static Object
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"
targetNamespace="http://www.example.org/person"
xmlns:tns="http://www.example.org/person" elementFormDefault="qualified">
<complexType name="Person">
<sequence>
<element name="Name" type="string"></element>
<element name="Age" type="int"></element>
<element name="id" 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="PERSON" typeName="Person">
<Column columnName="ID" primaryKey="true"/>
</Table>
<Command name="getFirstPerson" SQL="select * from PERSON where ID=1"
kind="Select"/>
3) I do:
HelperContext hc = HelperProvider.getDefaultContext();
PersonFactory.INSTANCE.register(hc);
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,
V.Kuravskiy

I'm no DAS expert. Your code assumes that DAS is using the default
helper context. From the evidence here it would seem that it is not.
I just loaded the DAS projects into my eclipse workspace to have a
little look around. I see there's a test class called
GeneratedCommandsTests with a method testReadCustomersStaticTypes that
seems to be doing what you want.
You can list the types in a given uri that a HelperContext knows about
using the tuscany specific API
org.apache.tuscany.sdo.api.SDOUtil#getTypes(HelperContext hc, String
uri)

OK, so I think you may have the metadata registered twice perhaps,
once dynamically and once statically. I say this because the class you
have an instance of is DynamicDataObjectImpl and not
AnyTypeDataObjectImpl. I wonder whether a dynamic registration of the
schema is masking the registration of the static classes?

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:

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?

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.

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?
