How to Save a file uploaded in WebDynpro Java to Windows server

Hi Guys,
I need to save a file uploaded in WebDynpro Java to a location on one of my companys many internal Window servers but I cannot get it to work. I do not get any errors with the following code, but NOTHING happens... And when I check the folder it is still emply... Please advise. I am particularly not sure about specifying the Path syntax. Also, I do have permission to write to this server. Is it even possible to save to a Windows server from WebDynpro??
//uploaded document already in context...
byte[] file = element.getFileResource();
            //    get the size of the uploaded file
            element.setFileSize(this.getFileSize(file));
            wdContext.currentContextElement().setFSize(this.getFSize(file));
            //    get the extension of the uploaded file
            element.setFileExtension(binaryType.getMimeType().getFileExtension());
            String fName = wdContext.currentContextElement().getFName();
            String fExt = wdContext.currentContextElement().getFileExtension();
            String foName1 = "
server01.w9\Files\P
HRP_Attachments\" + fName + ".pdf";
            File f1 = new File(foName1);
            DataOutputStream dos1;
            dos1 = new DataOutputStream(new FileOutputStream(f1));
            dos1.write(file);
            dos1.flush();
            dos1.close();

Hi Christiaan,
When specifying the path, make sure you escape the slashes
So, when you would normally use something like
\\server\path\file.txt
in your code you must use it in the form:
String fileName = "\\\\server\\path\\file.txt";
Hope this helps!

File Upload Using WebDynpro

Hi All,
I want to upload single or multiple CSV files using a user interface written in WebDynpros. The files will then be parsed and converted to XML.
I did something similar with jsps earlier but am not sure how to go about it with WebDynpros.
If anyone has already done something similar then please share your views.
Thanks in advance.

Hi Sathya,
         I guess you are trying to upload data from excel file(XLS format).
         If it is correct then you cannot do this in webdynpro, first you save the excel file as tab delimited.
         Open your excel file->save as->other formats->give file type as TEXT(Tab delemited).
         Now use this file to upload. It should work perfectly.

Flat File Upload from WebDynpro ABAP

Hi,
I am struggling to find a solution for this requirement and I hope I get some help from the Gurus here.
I have to upload a ".csv" file from the WebDynpro application, and then store the data in the flat file in a Z# table.
Can some one explain me how to go ahead with this requirement??
Regards,
Nadh

Hi Nrisimhanadh Yandamuri ,
After reading the csv file using file up load you can use the following code to tranfer the same to an itab of your required format
    DATA : loc_conv TYPE REF TO cl_abap_conv_in_ce,
      var_string TYPE string.
Convert XString to String
    CALL METHOD cl_abap_conv_in_ce=>create
      EXPORTING
        input       = item_content
        encoding    = 'UTF-8'
        replacement = '?'
        ignore_cerr = abap_true
      RECEIVING
        conv        = loc_conv.
*Read the file contents
    TRY.
        CALL METHOD loc_conv->read
          IMPORTING
            data = var_string.
      CATCH cx_sy_conversion_codepage.

File upload in webdynpro java

Hi, I have a reqirement where I have to upload the file ino server, and later user can down load the same from server.
i have seen file upload and down load example in SDN /docs/DOC-8061#15
but here they are just displaying the name and other details of the file that is trying upload but they are not really uploading the file in to the server. can any one guide me how to upload the file and where does the uploaded file resides in the server once it is succeefully uploded.
Regards,
Venki.

Hi Venki,
The following is the Procedure to DownLoad File from the Server Path.
1.) Take One Context Attribute named as "Texts" with Cardinality 0..n & Selection 0..1 & singleton = true .
2.) Take Two Context Attributes named " FileName " & " urlValue " of type String Under above Node "Texts".
3.) Bind Table UI Element & bind it's dataSource Property to the taken Context Node. Here it is "Texts".
4.) Insert One Column to The Table UI Element.
5.) Insert TableCellEditor( Take LinkToURL UI Element ).
6.) Bind " Texts.urlValue " to the references Property of the LinkToURL UI Element.
7.) Bind " Texts.FileName " to the text Property of the LinkToURL UI Element.
8.) All The UpLoaded Files in the Folder "FolderXYZ" are appeared as rows in the Table.
9.) Write the following code In the wdDoInit() Method of DownLoad View/After Upload Operation Performed.
     int count=0;
     WDWebResourceType obj=null;
     File folder=null;
     IWDMessageManager objMessageManager=wdComponentAPI.getMessageManager();

File Upload from Webdynpro to R/3 Server

Hi all
We have a scenario. In that we want to upload any type of file (can be .txt, .pdf, .doc, .xls, .jpg, .gif etc.) to the R/3 server. We r using a FileUpload UI Element.
The problem is we want to pass the contents of the file (any type of file) to the rfc.
If anybody knows the solution for this please help us.
(It will be of great help if u give the code)
Thanks & Regards
Aparnna

Hi Aparna,
It happens becuse u r trying to access the byte array of the file in a loop.
For small file it will not make any pblm, but for for big files, the loop may have to iterate millions of times which result in server hang.
So dont try to access the byte array in loop in ur code. Try to pass the byte array u r getting as whole to RFC.

Creating Progress Bar for File Upload

Hi, I'm trying to implement a progress bar indicator for a file upload in WebDynpro, without very good results.
I'm using a fileupload UI element, a TimerTrigger and a ProgressIndicator UI elements for this purpose.
It seems that using the fileupload UI element the iview is locked during the file upload, and therefore it prevents for the timer triggered action to be performed (this action updates the progress bar).
Additionally I havent been able to capture the transfered bytes from the upload. Maybe I'm using the wrong elements?
How could I achieve this. Has anyone done it?
I would really appreciate all the help I could get.
Homer Vargas

Hi,
Can anyone please tell me the way to upload file from client system to server.

     document.saveImageForm.method="post";
     document.saveImageForm.submit();

How to upload multiple files in Webdynpro using File upload Screen Element

Hi Experts,
Can anybody tell me how to upload multiple files/pdfs in webdynpro using file upload screen element, and also please tell me what is the maximum storage limit of RAWSTRING data type,Advance Thanks.
Regards,
Sandesh

Hi Sandesh,
this is simply not supported, not in WebDynpro nor in standard HTML.
A workaround is to upload a ZIP with all files and on server side unpack the ZIP and operate on the single files.
I hope it will help u..
----------------------OR-------------------------
As you know using File upload UI element we can upload only one file at a time. There may be a scenario where user may want to upload any no of files at a time which is not determined at design time. This can be acheived using the ACF UpDownload UI element which requires a security whiltelist to be created
http://scn.sap.com/docs/DOC-2270
----------------------OR-------------------------
You can use Table UI element.

Reg File Upload Object in abap Webdynpro

Hi Friends,
Would like to enquire one doubt in the file upload object in abap webdynpro.
By default when we press the browse button, near to the file name there is a button which shows the the file types like:
., *.html, ,gif,.jpeg etc.
Is there any way we can control that, as i have an requirement where in to upload only certain extension types.
thankyou.

HI,
I would suggest you to follow this approach :
1. Create a Table in your View in which FileUpload is there.
2. Populate this value with valid file extension.
3. Make it invisible by default.
4. Now when you have entered value in Fileupload and click on Ok button.
5. Check whether Mimetype matches any value in Table.
6. If it is invalid, Throw an error message and mke Table of Valid extension Visible.
Sample code to have Table with Valid entries.
types : begin of str,
             valid_ext type string,
         end of str.
data : wa type str,
          itab type table of str.
wa-valid_Ext = 'EXL'.
append wa to itab.
wa-valid_ext = 'DOC'.
append wa to itab.
lo_nd->bind_Table( itab ).
here lo_nd is your ref to node of Table having valid extensions.
7. Bind this Table's Visible property wiht wdui_visiblity .
8. Set it Visible - 02 , Inviisible - 01.
I hope it is clear.

IMP:ClassCastException while using File upload UI in Webdynpro for java

Hi All,
I have used a FileUpload UI element in my screen , which is working fine for only the first time we upload a file. If we try to upload any file with out refreshing the application , a ClassCastException is being thrown. Please help me in resolving the issue.
Thanks in advance.
Srikanth

Thank you!!
1. But when i use the File Upload UI and try to use the 'data' property to retrieve the bytes i am getting a null pointer exception meaning the data is not being picked up by the UI even though browsed file has data.
2. How I am I supposed to set the 'Resource' property while downloading a PDF which has UTF-16 text and picture??
Note: I have done the same scenario using WD04 java without any trouble.
