Download action listener maximum length

Question

Hi,
What should be the mzximum size of a file to be downloaded using a filedownload action listener
I am trying to download a file coming from bi publisher from adf and i have used filedownload action listener
But whenever the data is more than 200 kb or so it is failing and i am getting empty file. i have downloaded files of 156kb size or so...
What is the max size of it
Thanks,
Vinay

on click of download bt with download action listener the following method is called
    public void GenerateAirportAndAgent(FacesContext facesContext,
                                        OutputStream outputStream) {
        StringBuffer errorMessage = new StringBuffer();       
        ViewObjectImpl tripLocDetailsVO = (ViewObjectImpl) ADFUtils.findIterator("TripLocationDetailsIterator").getViewObject();
        String tripNumberString = null;
        BigDecimal tripNumber = null;
        Object tripNumberParam = tripLocDetailsVO.getNamedWhereClauseParam("bindTripNumber");
        if(tripNumberParam != null){
          tripNumber = (BigDecimal)tripNumberParam;
          tripNumberString = tripNumber.toString();
        String tripLocIDString = null;
        if(AdfFacesContext.getCurrentInstance().getPageFlowScope().get("AIRPORT_TRIP_LOCATION_ID") != null){
            tripLocIDString = (String)AdfFacesContext.getCurrentInstance().getPageFlowScope().get("AIRPORT_TRIP_LOCATION_ID");    
        String icao = null;
        Object icaoParam = tripLocDetailsVO.getNamedWhereClauseParam("bindIcao");
        if(icaoParam != null){
          icao = icaoParam.toString();
        tripLocDetailsVO.setRangeSize(-1);
        Row[] aircraftBriefVORows = tripLocDetailsVO.getAllRowsInRange();
          StringBuffer DST=new StringBuffer();
           StringBuffer STD=new StringBuffer();
        for (int i = 0; i < aircraftBriefVORows.length; i++) {
           ViewRowImpl tripLocationRow = (ViewRowImpl)aircraftBriefVORows;
//For each dept row, getting reference to empVO which contains all employees corresponding to current dept
RowIterator airPortLOcationVO = (RowIterator)tripLocationRow.getAttribute("AirportLocation");
while(airPortLOcationVO.hasNext()){
