Execute a CallableStatemaent to an Oracle database?

Hello!

How (or is it impossible) should I execute a callable statment  to a Oracle database and retrive the resultset in the returned resultset like:
resultSet = callableStatement.executeQuery();

I have only manged to retrive the resultset like this:
callableStatement.registerOutParameter(1, OracleTypes.CURSOR);
callableStatement.executeQuery();
resultSet = (ResultSet) callableStatement.getObject(1);

With other databases the first line of code usally works.

Best regards
Fredrik
