Problem displaying PDF in BSP

Hi All,

With the help of Craigs Blog

/people/sap.user72/blog/2004/11/10/bsphowto-generate-pdf-output-from-a-bsp

I coded a BSP to display PDF from a spool number.

I did everything mentioned in the blog. When i execute, the pdf gets displayed, however the data is some unconverted junk data. Can any one suggest what i am doing wrong here.

Heres the coding in the Event handler (OnInputProcessing) :

DATA: radioButtonGroup TYPE REF TO CL_HTMLB_RADIOBUTTONGROUP.

DATA: fileUpload TYPE REF TO CL_HTMLB_FILEUPLOAD.

DATA: cached_response TYPE REF TO if_http_response.

DATA: response TYPE REF TO if_http_response.

DATA: guid TYPE guid_32.

fileUpload ?= CL_HTMLB_MANAGER=>GET_DATA(

request = request

id = 'myUpload'

name = 'fileUpload' ).

file_name = fileUpload->file_name.

file_mime_type = fileUpload->file_content_type.

file_length = fileUpload->file_length.

file_content = fileUpload->file_content.

radioButtonGroup ?= CL_HTMLB_MANAGER=>GET_DATA(

request = request

id = 'display_type'

name = 'radioButtonGroup' ).

display_type = radioButtonGroup->selection.

IF display_type = 'convertspool'.

DATA: itab TYPE TLINE,

witab TYPE TABLE OF TLINE,

output TYPE STRING,

outputx TYPE XSTRING.

call function 'CONVERT_ABAPSPOOLJOB_2_PDF'

EXPORTING

SRC_SPOOLID = 0002344365

NO_DIALOG = 'X'

TABLES

PDF = witab

EXCEPTIONS

ERR_NO_ABAP_SPOOLJOB = 1

ERR_NO_SPOOLJOB = 2

ERR_NO_PERMISSION = 3

ERR_CONV_NOT_POSSIBLE = 4

ERR_BAD_DESTDEVICE = 5

USER_CANCELLED = 6

ERR_SPOOLERROR = 7

ERR_TEMSEERROR = 8

ERR_BTCJOB_OPEN_FAILED = 8

ERR_BTCJOB_SUBMIT_FAILED = 9

ERR_BTCJOB_CLOSE_FAILED = 10

others = 11.

if sy-subrc EQ 0.

LOOP AT witab INTO itab.

CONCATENATE

output

itab-tdline

INTO output.

ENDLOOP.

****Convert the Character String to Binary String

data: r_string type string.

data: R_XSTRING type xstring.

call function 'SCMS_STRING_TO_XSTRING'

EXPORTING

text = output

IMPORTING

buffer = outputx.

CREATE OBJECT cached_response TYPE CL_HTTP_RESPONSE EXPORTING

add_c_msg = 1.

l_pdf_len = xstrlen( outputx ).

cached_response->set_data( data = outputx

length = l_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

display_url.

cl_http_server=>server_cache_upload( url = display_url

response = cached_response ).

ENDIF.

RETURN.

ENDIF.

Regards

Sri

    With the help of some other posts and blogs.. am able to display the pdf now.

    However, the default magnification(zoom) is always 44.5%. Any ideas as to how this can be increased or set to a default value.

    Done. Set the standard zoom in PDF settings.

    Thanks
