Display file in the desktop

[Former Member]

Hello Experts,

We have ESS Leave application built using Java web dynpro, but the leave records will be sent to SAP server using some custom function module.

Recently we got a requirement to attach files while creating a leave request. We implemented  GOS(Generic Object Services) functionality. So attached file from java webdynpro will be converted to a XSTRING and sent to the SAP server. I can save and retrieve the file content in the SAP server. Now the problem is i am unable to display the file content.I cannot use  cl_wd_runtime_services=>attach_file_to_response since it can only work with ABAP Webdynpro. So the function module dumps. Pls suggest.

Any suggestion is highly appreciated.

Thanks

Vivek

Hey Vivek,

I believe ı can help you.

1. Create a button and his action on webdynpro.

2. Then create a simple zcomponenet and call it like a popup

3. create z sicf service

4. In your zcomponenet in .htm part call this sicf serivce with header guid like

  lv_item_url = cl_crm_web_utility=>create_url( iv_path = '/sap/crm/zcrm_doc'

   iv_absolute = 'X'

   iv_query = lv_query

   iv_in_same_session = ''

   iv_no_cookie = 'X'

   "iv_server_object = server

   ).

5. in your webservice

method IF_HTTP_EXTENSION~HANDLE_REQUEST.

      DATA: lv_guid_s    TYPE string,

           lv_guid      TYPE comt_product_guid,

           lv_item_guid TYPE comt_product_guid,

           lt_content   TYPE zcrm_document_cont_tab,

           ls_content   TYPE zcrm_document_cont,

           lv_value     TYPE string,

           xstring      TYPE xstring,

           lv_size      TYPE i.

***************************************************************************************

***************************************************************************************

     CALL METHOD server->request->get_form_data

       EXPORTING

         name = 'guid'

       CHANGING

         data = lv_guid_s.

     lv_guid = lv_guid_s.

     clear lt_content.

     lt_content = zcrm_document_tools=>get_document_content(  iv_guid = lv_guid ).

     IF lt_content is not INITIAL.

     LOOP AT lt_content INTO ls_content WHERE mime_type = 'image/jpeg' OR mime_type = 'image/png'.

     ENDLOOP.

     CHECK sy-subrc EQ 0.

     DATA: lv_dummy     TYPE string,

           lv_ext       TYPE string,

           lv_mime_type TYPE string.

     SPLIT ls_content-mime_type AT '/' INTO lv_dummy lv_ext .

     CONCATENATE 'attachment; filename=export_' lv_guid_s '.' lv_ext  INTO lv_value.

     server->response->set_header_field( name  = 'Content-Disposition' "#EC NOTEXT

                                     value = lv_value ).

*     -> create response

     lv_mime_type = ls_content-mime_type.

     server->response->set_header_field( name  = 'Content-Type' "#EC NOTEXT

                                         value = lv_mime_type ).

     server->response->set_header_field( name  = 'expires'   "#EC NOTEXT

                                         value = '0' ).

     lv_size = ls_content-filesize.

     CALL FUNCTION 'SCMS_BINARY_TO_XSTRING'

       EXPORTING

         input_length = lv_size

*       FIRST_LINE   = 0

*       LAST_LINE    = 0

       IMPORTING

         buffer       = xstring

       TABLES

         binary_tab   = ls_content-content

*     EXCEPTIONS

*       FAILED       = 1

*       OTHERS       = 2

       .

     IF sy-subrc <> 0.

* Implement suitable error handling here

     ENDIF.

IF  xstring is not INITIAL .

     server->response->set_data( data = xstring ).

ENDIF.

     else.

       CLEAR xstring.

     ENDIF.

6. it will return you your file url and open it in your htm.

Simply you can display file with url of it. There is other ways to create url you can search.
