Result Set returned iteration.Please advise

Question

I am invoking a Stored Function from my Java code that returns back
a result set.
I have put a break point on my code.
The value of the rs = OracleResultSetImpl(id=59)
and when the cursor reaches while(rs.next()),it does not go in this loop
and exits out.
Does this mean that there are no records returned back ?
But then the rs should be null instead of showing :OracleResultSetImpl(id=59)
public synchronized ResultSet getAcctChgData(String OrderNo) throws SQLException {
           CallableStatement loadAcctChgStatement=null;
         ResultSet rs=null;
         try
              loadAcctChgStatement = con.prepareCall("{call ? := SF_ACCOUNTCHG(?)}"); //This is oracle function
              loadAcctChgStatement.registerOutParameter(1,OracleTypes.CURSOR);
              loadAcctChgStatement.setString(2,OrderNo);
              loadAcctChgStatement.execute();
              rs = (ResultSet)loadAcctChgStatement.getObject(1);
              while(rs.next()){
                   String f_OrderID  = rs.getString("FixOrderID");
                   String f_EffTs    = rs.getString("EffTs");
                   String f_ClrAcct  = rs.getString("ClrAcct");     
         }catch (SQLException e){
          logger.error("No record found for Order No " + OrderNo);
         return rs;
     }

Yes, and I'm suprised you don't get a classCastException, actually. I'd've expected you to get a return code through the output parameter.
