passing a cursor to a stored procedure from Java

Hello all,
how can I pass a cursor as an in/out-parameter to a procedure from Java? I tried the following but it didn't work. When I call the procedure from commandline it works fine.

...

ResultSet refcur = null;
CallableStatement statement = conn.prepareCall("{ ? = call sp_CustomerVerify (?,?)}");

statement.registerOutParameter(1, OracleTypes.CURSOR);
statement.setObject(2, refcur);
statement.setString(3, custno);
statement.execute();
