Getting a ResultSet from a stored function

Question

Hi everybody.
I don't know if it's possible but i would like call a stored function with JDBC, and that function returns not a single value (like a VARCHAR2 or a NUMBER) but the "equivallent of a Java ResultSet".
With JDBC, i can execute a query like "SELECT * FROM Emp" and fetch a set of row in a ResultSet.
Instead of preparing and executing a SQL query from my Java source, i would preferred calling a stored function.
But i don't know which data type my function should return.
I would like to know if such a thing is possible.
Maybe somebody have an sample source code ...
Thanks.

You can get values OUT of the procedure by (lines with registerOutParameter):
cstmt = conn.prepareCall("{call hrx_get_empl_benefit_cost(?,?,?,?,?,?,?)}");
cstmt.setInt(1,employee.getId());
cstmt.setInt(2,plan.getId());
cstmt.setString(3,cvgAmtOrLevel);
cstmt.setString(4,effDate);
cstmt.registerOutParameter(5,Types.VARCHAR);
cstmt.registerOutParameter(6,Types.VARCHAR);
cstmt.registerOutParameter(7,Types.VARCHAR);
cstmt.execute();
I do not think it returns a resultSet like you are thinking. I guess you are talking about getting values out and not a cursor of records or several records of values.
