BSP FIle upload

Hi,
I searched but could not find an answer...I am working on a program that itseems worked till the last few days...not sure why it stopped working suddenly. I was able to fix it now, but am wondering how to retrieve the old attachments uploaded using this app.
This BSP app is used to store documents.
Step-1:Simple BSP form upload. In the event handler, the cData is read using cl_http_entity->get_cdata. This is stored in a table as a string along with filename, file type etc.
Step-2: To download the document from Step-1, the string from Step-1 is converted to xstring using SCMS-STRING-TO-XSTRING and then the response is set using:
runtime->server->response->set_data( data = lxstringdata length = xstrtlen ).
This no longer works - it gives garbage data...
I converted it to read binary data while uploading (cl_http_entity->get_cdata) and it works fine now - but any idea on how I can read the files that have been created so far? I was told that it was working atleast a few days back..
Thanks in advance.

Any help from the gurus?

File Upload in BSP Applications and store in Application server

Hi we have requirement to store the attachments from BSP application into the external/internal storage space connected to application server.
I search for weblogs and all talking about <a href="http://help.sap.com/saphelp_me21sp2/helpdata/en/eb/8c683c8de8a969e10000000a114084/content.htm">File Upload in BSP Applications and store in MIME Repository</a>.
But our requirement is upload and store(no need to read the file content) attachments from BSP page into file server, and then make a link back in BSP page to open.
I know we can handle documnets in R/3 using DMS, but our system is SRM.
Please give a suggestion and solution.

The archived document can then be displayed by inserting the (IXOS-web client-)link to the BSP page (e.g. http://193.228.208.78:4060/archive.dll/get?arc=2T&doc=44439F1B4F701E65E1000000C1E4D00A).

Hello Bharan,
the file upload must run in its own BSP application. Otherwise the header for the file content is not filled properly. You can use an iframe to embed the upload application into a BPS web interface for example.

Flat file Upload BSP page

Hi Marc,
I am following the July version of how-to. When generating the BSP page, I am told checkbrowser.htm and js.htm are not available. When I create a checkbrowser.htm and point the include to js3.htm, which is one of the page fragment available, there are a few other errors coming out. What am I missing?

Do you already know if the flat file upload is possible from a multi planning area? Because I get the error message that my multi planning area does not exist when executing the function.
Thnx.

How to modify the field lengh of file upload

Hi All,
   I am facing a problem with u201Cuploadu201D filed length in BSP application.
When we upload the file in BSP page, the path displayed should be the full path (i.e. from where the file is being upload the file)
Now this field is appearing 20 char length
Now I want to increase the length of the upload field (Input field) to be 100 char so that the path is visible.
In the current application the file upload is being done through a structure (attributes)
In this structure the fields are like this
PAGE_NAME
ID
FOR
TAGS
ROW_INDEX
COLUMN_INDEX
OTR_NAME
REQUIRED_NAME
MAXLENGTH
SIZE
TABLE_NAME
ON_SELECT
VALUE
DISABLED
ONCLICK
TEXT
TYPE
Using this method:
CALL METHOD cl_htmlb_fileupload=>factory
          EXPORTING
            Id      = ls_form_save-id
          RECEIVING
            Element = lv_fileup.
        bee_table->add ( level = 2 element = lv_fileup ).
This cl_htmlb_fileupload is named as class interface.
Which has the CLG_HTMLB_FILEUPLOAD (it is a class) it is defined in attributes.
In this class it has the attribute u201CSIZEu201D by default string 20.
Now I need to change this attribute length from 20 to 100
For this I copied the standard class CL_HTMLB_FILEUPLOAD into ZCL_HTMLB_FILEUPLOAD.
This ZCL_HTMLB_FILEUPLOAD contains all attributes of the standard class CL_HTMLB_FILEUPLOAD
Including the one class (CLG_HTMLB_FILEUPLOAD), this is defined as an attribute (ABOVE MENTIONED?)
This class is appearing in non editable mode, so   I have copied this class into zclass (ZCLG_HTMLB_FILEUPLOAD).but still I am not able to edit the attribute called u201Csizeu201D
And also I am not bale to add the zclass in place of the ZCLG_HTMLB_FILEUPLOAD
Kindly tell me how to modify the length of the field u201Csize u201Cand also how to add the zclass in the attributes of one class (syntax)
Thanks in advance
Rambabu.A

Hi,
Class CLG_HTMLB_FILEUPLOAD is a class automatically generated when a BSP Element is created. You should not change/create such a class, unless by creating your own BSP Element.
As per your requirement, you can use the SIZE parameter of method factory:
ls_form_save-size = '100'.
CALL METHOD cl_htmlb_fileupload=>factory
EXPORTING
Id = ls_form_save-id
Size = ls_form_save-size
RECEIVING
Element = lv_fileup.

BSP File Download - .TIF problems

Dear all!
I haven't been able to fix this problem,
please see my post for further information. I am using SAP.help coding to display files in BSPs (6.20, "BSP with flow logic" pages used). See the coding below.
Somehow .tif files can not be displayed. Every other mime type works fine.
Thanks,
Chris
Dear all!
In a quite complex file upload and download scenario which works fine we use the following coding to display files received from the backend in our page.
OnInitialization: receives file backend data such as filesize, content(xstring) and mimetype.
This works all fine. Mimetype is delivered correctly.
OnInputProcessing:
This has been taken from the help.sap.com documentation -
    runtime->server->response->set_data( mycontent ).
      runtime->server->response->set_header_field(
        name   = 'Content-Disposition'
        value = lv_downname ).
    runtime->server->response->set_header_field( name = 'Content-Type' value = mymimetype ).
    runtime->server->response->set_header_field( name = 'Content-Length' value = myfilesize ).
    runtime->server->response->delete_header_field( name = 'Cache-Control' ).
    runtime->server->response->delete_header_field( name = 'Expires' ).
    navigation->response_complete( ).
RESULT:
the file is displayed fine. When trying to save the displayed file locally on the hard disc, the mimetype is not available. The system (Windows XP) provides only .bmp as file type. Also the context menu entry "Properties" of the displayed file shows NOT AVAILABLE as mimetype.
Is this a common problem? How can I achieve to have the mimetype information available for a save?
Thankx,
Christoph

Hi,
I am getting an error, when I try to download the document from the bsp-page.
I have uploaded the document to the server-cache as mentioned above. If I test it on the standalone machine, everything works fine. But when I have to connect to the BSP-Application through an EP I am getting the error:

Can you please help me?
Points will be assigned
Thank you
Ramona L.

Dear Ramona,
to find out what is going wrong you can try to debug the application.
Therefore please open the application Z_KPI_LOG in SE80 (BSP-Application) and go to page Z_KPI_LOG2.HTM. Here you need to set an external-Breakpoint. Now start the application. During debugging of the page look out for objects which are not instantiated (= initial). As soon as a method should be called for and inital object you get your error message.
Please note: if you have many objects (e.g. textitems) on the page, it way take some time for you to find out in the debugger which object is initial (= not instantiated).
The typical reasons for this kind of error in WebInterfaces is:
- a method for an object should be called, but the object is not instantiated
The reason why the object is not instantiated could be (in your case):
- a text for an text element is missing
- there is an error in the transport (So please compare page Z_KPI_LOG2.HTM in your development system and your system where you are getting the error) or try to transport the application again. Also checked if parts of the application are locked in another transport request.
Hope this helps.

BASIC: Flat File Uploads to Web Reports - Notification Status

Hi,
I have excel based Notifications (Some legal cases) with their status in text format.
I would like to show them on a WAD based report.
Kindly suggest how I can do the same.
Thanks in advance
Pranab

Pranab,
you could upload them as documents if required and display the same.
Otherwise - you can upload the same into MIME repository and use the template to display the same using the document Web Item.
Otherwise you can have a BSP that uploads the data into MIME - the user could do this and then display the same in a BSP page instead.
If security is not a big concern then you could upload the same into sites like zohocreator and expose the links on the web template - here the user can also update the status / change the excel files if required - something like Google spreadsheets..

File Upload on Visual Composer

Dear colleagues,
I need to build the functionality to do a File upload on Visual Composer. The user should be able to select a file from his local PC and upload it into a table or DSO.
I have created a function module that uses the function 'GUI_UPLOAD' to do the upload. If I execute the FM from transaction SE37 it works fine, selects the file and loads the data into the table. However, if I embed that FM into Visual Composer it does not work anymore.
Is it because it uses GUI technology that cannot be called from java environment of VC?
Anybody has a hint on how to solve this? Is there any standard functionality to do it?
Thanks,
Salvador Gimeno

Yes, the GUI_UPLOAD relies on the "SAP Gui connection" which is not possible in a Web environnement like the Visual Composer.
In languages such as Web Dynpro (Java or ABAP) or BSP, you can upload file to the server.
You might have to "mix" technologies to provide upload and still keep using VC.

I think this upload functionality is about to be released with Ehp1

How to popup file upload tag when we click on a button?

Hi All,

Please help me on this.

if you're using a document class ascircle, that should something like:
package{
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class ascircle extends MovieClip{
public function ascircle(){
init();
private function init():void{
stage.addEventListener(MouseEvent.CLICK,clickF);
function clickF(e:MouseEvent):void{
Circle.play();
// if you're adding code to the main timeline, you would use:
stage.addEventListener(MouseEvent.CLICK,clickF);
function clickF(e:MouseEvent):void{
Circle.play();

Error "A web exception has occurred during file upload" when trying to import ESXi image file into Update Manager

I'm encountering this error and not sure how to fix, I'm quite new to vCenter so please bear with me.
I'm trying out vCenter 5.1 with Update Manager 5.1 right now. No license key has been entered and I still have 50 odd days to try it out.
2 ESXi hosts are being managed by this vCenter, and they're both running ESXi 4.0
I'm looking to use Update Manager to try to upgrade the ESXi 4.0 hosts to ESXi 5.1
I downloaded the image file VMware-VIMSetup-all-5.1.0-799735.iso from VMWare website, and is looking to import it using the Update Manager so I can update the ESXi hosts, but I keep on getting the error:
File name: VMware-VIMSetup-all-5.1.0-799735.iso
Failed to transfer data
Error was: A web exception has occurred during file upload
I tried importing it by using vSphere client to connect to vCenter server both remotely and locally, with firewall disabled.
I've read http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1026602
I've disabled firewall, and there is no anti-virus program on the server. I've also restarted the machine several times, to no avail, I didn't reinstall update manager because the whole Windows and VCenter installations are clean from scratch.
I logged into the vSphere Client using Active Directory credentials, and I've made all Domain Admins (which my account is a member of) part of the administrator group on the vCenter server. I can't log in using admin@System-Domain because it tells me I don't have permissions for it, I still haven't really had the chance to figure out why that is and not sure if that makes a difference.
Also, I'm fairly certain I'm using the right image file, as I've burned some DVD's used that image file to upgrade some other ESXi hosts. Unless there's a special image file I need to download?
I'm at lost on what I can do to make it work. Please advise.
Thanks.

The ISO file you mentioned is the one for vCenter Server. What you need is the "VMware-VMvisor-Installer-5.1.0-799733.x86_64.iso" (or VMware-VMvisor-Installer-201210001-838463.x86_64.iso) for the ESXi host.
