Problem with store ResultSet and show result in table

Question

Hi, I'm kind of new in ADF, I need to store ResultSet and show result in table-component. I have two problems:
1) I get my ResultSet by calling callStoredProcedure(...) and this returns actually ref_cursor as ResultSet.
When I try to println() contains of this result set in this method - it works OK (commented part),
but when I want to println() somewhere else (eg. in retrieveRefCursor() method) it doesn't work.
The problem is that the scrollability of the ResultSet is lost - it becomes a TYPE_FORWARD_ONLY ResultSet.
Is there any way to store data from ref_cursor for a long time?
2) My second problem is "store any result set and show this data in table". I have tried use method storeNewResultSet() but
without result (table contains only "No rows yet" and everything seems to be OK - no exception, no warning, no error...).
I have tried to call this method with ResultSet from select on dbs (without resultSet as ref_cursor ) - no result with createRowFromResultSet(),
storeNewResultSet(), setUserDataForCollection()...
I've tried a lot of ways to do this, but it doesn't work. I really don't know how to make it so it can work.
Thanks for your help.

Hi I have the same problem like you ...
My SQL Definition:
CREATE OR REPLACE TYPE RMSPRD.NB_TAB_STOREDATA is table of NB_STOREDATA_REC
CREATE OR REPLACE TYPE RMSPRD.NB_STOREDATA_REC AS OBJECT (
   v_title            VARCHAR2(100),
   v_store            VARCHAR2(50),
   v_sales            NUMBER(20,4),
   v_cost             NUMBER(20,4),
   v_units            NUMBER(12,4),
   v_margin           NUMBER(6,2),
   v_ly_sales         NUMBER(20,4),
   v_ly_cost          NUMBER(20,4),
   v_ly_units         NUMBER(12,4),
   v_ly_margin        NUMBER(6,2),
   v_sales_variance   NUMBER(6,2)
CREATE OR REPLACE PACKAGE RMSPRD.NB_SALES_DATA

      RETURN nb_tab_storedata;
I have a PLSQL function .. that will return table ..
when i use this in sql developer it is working fine....
select * from table (NB_SALES_DATA.sales_data_by_format_gen('TSC',
                                    '05-Aug-2012',
                                    '01-Aug-2012') )
it returning table format record.
I am not able to call from VO object. ...
Hope you can help me .. please tell me step by step process...
protected Object callStoredFunction(int sqlReturnType, String stmt,
Object[] bindVars) {
System.out.println("--> 1");
CallableStatement st = null;
try {
st = getDBTransaction().createCallableStatement("begin ? := " +"NB_SALES_DATA.sales_data_by_format_gen('TSC','05-Aug-2012','01-Aug-2012') ; end;", 0);
System.out.println("--> 2");
st.executeUpdate();
System.out.println("--> 3");
return st.getObject(1);
catch (SQLException e) {
e.printStackTrace();
throw new JboException(e);
