使用游标Oracle插入数据

Question

Database: Oracle 11gr2; Web application : JSP(Java) I have two tables:

Cities(***Id***, Name); Id is the Primary Key
Persons(***IdPers***, Name, IdCity_FK); IdCity is Foreign Key

IdCity_FK reffers to column Id from Cities.

The question: how to insert data from a insert.jsp page which has the following fiels:Person's name, City.

I want the user to enter his name and to select a city from some ListBox dynamically generated (using Cursor Oracle or a other method).
For instance, one does not enter : Andrew, 12, but enters Andrew and select New York. I managed to do this by using Oracle REF CURSOR, but when clicking submit I get error. I think it does not pass an int value as parameter.

The code

 create or replace 
FUNCTION GET_CITIES
RETURN CITYPKG.ref_cursor
AS cities_cursor CityPkg.ref_cursor;
BEGIN
  OPEN cities_cursor FOR
  SELECT id, nume FROM CITY;
  RETURN CITIES_cursor;
END;

In the JSP page for editing I have a jspforward tag which sends me to a page which handles the form with request.getParameter... and calls a function which has 2 parameters: one is String the other one is int. The int one inserts the corresponding foreign key in the database. Thank you in advance.
