Stored PL/SQL function that returns REF CURSOR type

Question

Hello everyone,
I've come through the following problem:
1.- I created an PL/SQL stored procedure which returns a REF CURSOR element, definition looks like this:
PACKAGE PKG_LISTADOS AS
TYPE tuplas IS REF CURSOR;
/* Procedimientos exportados por el paquete */
PROCEDURE inicializarModuloListados;
FUNCTION recaudacionUltimoMes(medioPago DEF_MEDIO_PAGO.MEDIO_PAGO%TYPE)
RETURN tuplas;
2.- Now I would like to call the stored procedure and retrieve the PL/SQL cursor as a ResultSet Java Object. The code I wrote is this:
Connection conn;
XmlDocument paramDef;
conn=poolMgr.getConnection str_poolDBConnection);
try
CallableStatement cstmt=conn.prepareCall("{?=call PKG_LISTADOS.recaudacionUltimoMes(?)}");
cstmt.registerOutParameter(1, java.sql.Types.OTHER);
cstmt.setString(2, "MONEDA");
cstmt.executeQuery();
ResultSet rs=(ResultSet)cstmt.getObject(1);
catch(SQLException sqlE)
3.- However, I can't make it OK, all the time I get the following error:
SQL Error(17004), java.sql.SQLException: Non valid column type
May anyone help me with this, thanks in advance:
Miguel-Angel

Do something like the following:
cstmt = conn.prepareCall("{call customer_proc(?, ?)}");
//Set the first parameter
cstmt.setInt(1, 40);
//Register to get the Cursor parameter back from the procedure
cstmt.registerOutParameter(2, OracleTypes.CURSOR);
cstmt.execute();
ResultSet cursor = ((OracleCallableStatement)cstmt).getCursor(2);
while(cursor.next())
System.out.println("CUSTOMER NAME: " + cursor.getString(1));
System.out.println("CUSTOMER AGE: " + cursor.getInt(2));
cursor.close();
null
