Error getting VARCHAR2 in a object using JCA DB Adapter.

Question

I am facing a problem with the JCA db Adapter and i am not able to solve.
I have created an Oracle Object like:
CREATE OR REPLACE TYPE FACTURAE AS OBJECT
( MODALIDAD VARCHAR2(1),--I
TipoEmisorfactura VARCHAR2(2),--EM
Then i have created a procedure which returns the mentioned type;
FUNCTION FUsorgen_obtenerdatosFactura (IDFACTURA IN NUMBER,strTipoFactura IN VARCHAR2)RETURN FACTURAE
IS
Then i have created a JCA db Adapter in Jdeveloper obtaining an wsdl and a xsd schema. Both files are valid
Finally i have created a business service based on this wsdl. When i have tested this y get an xml like:
<OutputParams>
<MODALIDAD>???</MODALIDAD>
<TipoEmisorfactura>12</TipoEmisorfactura>
</OutputParams>
I have checked that executing the procedure with the same parameters the field "MODALIDAD" has value "I" so it is not null nor "???".
Have anybody an idea what is happening? Is there a known bug with personaliced objects and DB Adapter?
Best Regards.

Answer 1

Perhaps you could post your XSD and the instance XML that you provide for the input parameters.
The generated XML for the output parameters should look something like the following.
<OutputParameters ...>
    <FUsorgen_obtenerdatosFactura>
        <MODALIDAD> ... </MODALIDAD>
        <TipoEmisorfactura> ... </TipoEmisorfactura>
    </FUsorgen_obtenerdatosFactura>
</OutputParameters>Notice that the function name is the name of pseudo-parameter encapsulating the attributes of your object type.
