PDF not displaying

Question

Hi,
I'm new to BSP's and seem to have a problem. When a form has to be displayed in a separate window the window comes up but with the error:
BSP Exception: Das Objekt 43701DE84054085702000000A3C401DA.pdf in der URL /sap(bD1lbiZjPTIxMCZkPW1pbiZ3PTk4MDM1ODAr)/bc/bsp/sap/zdi_spp_main/43701DE84054085702000000A3C401DA.pdf ist nicht gültig.
Here is the code also:
DATA: cached_response TYPE REF TO if_http_response.
CREATE OBJECT cached_response TYPE cl_http_response EXPORTING add_c_msg
= 1.
confirm->pdf_len = XSTRLEN( confirm->pdf_xstring ).
cached_response->set_data( data   = confirm->pdf_xstring
                      length = confirm->pdf_len ).
cached_response->set_header_field( name  =
if_http_header_fields=>content_type
                                     value = 'application/pdf' ).
  cached_response->set_status( code = 200 reason = 'OK' ).
  cached_response->server_cache_expire_rel( expires_rel = 180 ).
  CALL FUNCTION 'GUID_CREATE'
    IMPORTING
      ev_guid_32 = guid.
  CONCATENATE runtime->application_url '/' guid '.pdf'
                INTO l_display_url.
  cl_http_server=>server_cache_upload( url      = l_display_url
                                       response = cached_response ).
Any help would be greatly appreciated.
Thanks
Bradley

Hi Bradley,
   The following code i am using since long time we did not faced any problem till now you can check this code with your code.
   This code was return for to download the data inot excel and pdf format
Import parameters for this method are
DATA TYPE XSTRING
OPTION TYPE STRING
RESPONSE TYPE REF TO IF_HTTP_RESPONSE
NAVIGATION TYPE REF TO IF_BSP_NAVIGATION
data:  l_app_type  type string,
       l_filename  type string,
       l_xstring  type xstring,  "needed for HTTP response
       l_xlen       type i.
For Downloading into PDF format
if option eq 'PDF'.
setting Content Type
  move 'application/pdf' to l_app_type.
  move 'attachment; filename=webforms.pdf' to l_filename.
elseif option eq 'XLS'.
Setting Content Type
  move 'application/msexcel' to l_app_type.
  move 'attachment; filename=webforms.xls' to l_filename.
endif.
clear l_xstring.
l_xstring = data.
Fill HTTP request
response->set_header_field( name  = 'content-type'
                            value = l_app_type ).
response->delete_header_field(
                    name = if_http_header_fields=>cache_control ).
response->delete_header_field(
                    name = if_http_header_fields=>expires ).
response->delete_header_field(
                    name = if_http_header_fields=>pragma ).
response->set_header_field(
                     name  = 'content-disposition'
                     value = l_filename ).
finally display PDF format in Browser
l_xlen = xstrlen( l_xstring ).
response->set_data( data   = l_xstring
                    length = l_xlen ).
navigation->response_complete( ).
