Get object type attribute value

Question

1 am trying binding Oracle Object types to java object types using the ORAData interface.
I created a simple object type called att_mesg_type with the syntax
create type att_mesg_type as object (subject varchar2(200),Text varchar2(1000));
I then created a class called attMesgType using Jpublisher which implements the interface.
The getSubject() and getText() method return '???'.
Anybody has any insights? Any inputs are appreciated.

declare
attr_name varchar2(10) := 'ATTR1';
attr_value varchar2(50);
type_instance MyType := MyType('VALUE 1', 'VALUE 2');
begin
    execute immediate 'declare type_instance MyType := :1; begin :2 := type_instance.' || attr_name || '; end;'
      using type_instance,out attr_value;
    dbms_output.put_line(attr_value);
end;
VALUE 1
