Getting array of Oracle Objects

[Prashanth menon]

Hi
I am using CallableStatements . The Oracle object I have is testobjtype and the package is testpkg. How do I register the outParameter of a varray type? I am getting error when I create a ArrayDescriptor ...

The code is below.

OracleCallableStatement callableStatement = (OracleCallableStatement)
con.prepareCall ("{ ? = call TESTPKG.testf(?)}");

callableStatement.setString(2, "test");

Object elements[] = new Object[20];

ArrayDescriptor desc = ArrayDescriptor.createDescriptor("TYPE_VARRAY", con);
/*
I tried with this also
ArrayDescriptor desc = ArrayDescriptor.createDescriptor("testobjtype", con);
*/

ARRAY newArray = new ARRAY(desc, con, elements);
callableStatement.registerOutParameter(1, OracleTypes.ARRAY, "newArray");
callableStatement.execute();

ResultSet rs = (ResultSet)callableStatement.getObject (1);

ERROR:
