How to upload excel file in Webdynpro application using ABAP

Hi Experts,
Am developing a webdynpro application in which it will take an excel file as input and display the contents in the form of a table in output. I am able to upload tab delimited text file and populate the table using the below code but not able to do the same with .xls file. Pls let me know if I need to use a different function module for upload excel file.
get single attribute
wd_context->get_attribute(
    EXPORTING
      name = `DATASOURCE`
    IMPORTING
      value = l_xstring ).
CALL FUNCTION 'HR_KR_XSTRING_TO_STRING'
    EXPORTING
      in_xstring = l_xstring
    IMPORTING
      out_string = l_string.
SPLIT l_string AT cl_abap_char_utilities=>newline INTO TABLE i_data.
Bind With table Element.
LOOP AT i_data INTO l_string.
    SPLIT l_string AT cl_abap_char_utilities=>horizontal_tab INTO TABLE fields.
    READ TABLE fields INTO lv_field INDEX 1.
    fs_table-name = lv_field.
    READ TABLE fields INTO lv_field INDEX 2.
    fs_table-age = lv_field.
    APPEND fs_table TO t_table1.
ENDLOOP.
lo_nd_data = wd_context->get_child_node( 'DATA_TAB' ).
lo_nd_data->bind_table( T_TABLE1 ).
Thanks,

How to upload Excel file in BI using function module in abap program

How to upload Excel file in BI using function module in abap program?

Hi Anuj,
To upload the file , you can try a standard program "RSEPSFTP" .
while you execute the program , a selection screen appears in which the inputs should be give as
RFC destination - The target server name
FTP command- PUT
local file - your file name
local directory - path of your local file
remote file - your target file name
remote directory - where it has to be stored
Hope this is useful for you
Thanks & regards

Help Required:How Upload Excel file Into Oracle Table Using PLSQL Procedure

Please Help , Urgent Help Needed.
Requirement is to Upload Excel file Into Oracle Table Using PLSQL Procedure/Package.
Case's are :
1. Excel File is On Users/ Client PC.
2. Application is on Remote Server(Oracle Forms D2k).
3. User Is Using Application Using Terminal Server LogIn.
4. So If User Will Use to GET_FILE_NAME() function of D2K to Get Excel File , D2k Will Try to pick File from That Remote Server(Bcs User Logind from Terminal Server Option).
5. Cannot Use Util_File Package Or Oracle Directory to Place That File on Server.
6. we are Using Oracle 8.7
So Need Some PL/SQL Package or Fuction/ Procedure to Upload Excel file on User's Pc to Oracle Table.
Please Guide me wd some Code. or with Some Pl/SQL Package, or With SOme Hint. Or any Link ....
Jus help to Sort This Issue ........
you can also write me on :
[email protected], [email protected]

TEXT_IO is a PL/SQL package available only in Forms (you'll want to post in the Forms forum for more information). It is not available in a stored procedure in the database (where the equivalent package is UTL_FILE).
If the Terminal Server machine and the database machine do not have access to the file system on the client machine, no application running on either machine will have access to the file. Barring exceptional setups (like the FTP server on the client machine), your applications are not going to have more access to the client machine than the operating system does.
If you map the client drives from the Terminal Server box, there is the potential for your Forms application to access those files. If you want the files to be accessible to a stored procedure in the database, you'll need to move the files somewhere the database can access them.

How to upload a file in BPEL Console Using JSP in JDeveloper, please help..

Please I am new to Jdeveloper and to BPEL Process of OASuite,I want to know , how to upload a file in BPEL process using JSP in Jdeveloper IDE.
The main aim is first we need to upload a file in JSP , it has to go to BPEL Process & it has to read the file & write the respective file in return to JSP through BPEL Process. Please I am in Urgent need of the Query , please help me ASAP.
Send to me response Please.....................................

Hi,
I thin that you asked the same question before and I premember that I ointed you to the ADF BC developer guide and the SRDemo if your application uses JSF. For plain JSP - if you Google for: JSP and file upload then you find plenty of sources for JSP and Struts.
The remaining part is how to stiff the file into a BPEL service on the middle tier. For this I recommended to ask your question on the BPEL forum
BPEL
Note that the BPEL integration would be easier if it was done on the middle tier and not onthe client

Hi,
ADF Faces provides you with the file upload component
http://download-uk.oracle.com/docs/html/B25947_01/web_complex006.htm#CEGCEDHF
http://download-uk.oracle.com/docs/html/B25947_01/appendixa007.htm#CHDEDCFA
This gives you a handle to the file content. However, uploading files through a service is different and I suggest to consult teh BPEL forum for this BPEL

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.

How do upload a file to the application server into a directory?

hi to all,
i want to upload file into the database..i need upload the file into the application server and save it to a directory..is there any way?where i can read about this?any information?
ashwiny

Hello,
First, we need to determine the terms we are using, in order to avoid confusion. We (including the documentation) are using "upload" to describe storing the file on the server, and "download" to pull it from the server into local machine.
You can use the "File Browse" item to upload any file you need from your local machine and into a database table. The default APEX configuration (in the dads.conf file) stored the uploaded file in a table called wwv_flow_file_objects$. In your application, you can access this table using a view called APEX_APPLICATION_FILES.
After you uploaded a file, any user can access it, using the download procedure described in the reference I gave you. The download procedure gives you an option to store the download file anywhere you need, using the "Open/Save" dialog box.
I believe this is covering everything you need. If you still having problems, please consider posting the relevant application pages on apex.oracle.com. It will be easier to understand and help you.

Arie.

Simply use GUI_UPLOAD function to get data from excel, txt etc.., into internal table in program.
Try this program.. It performs downloading and uploading functions in both excel and .txt format.

How to upload company logo in webdynpro application

Hi,
I need to upload the company logo in the View of a Webdynpro application.
Can someone give me the steps for the same to be done?
Thanks,
Kundan

Hi kundan,
Store the images in the MIME Directory.
-> Declare a simple type data type in the Java Dictionary.
->Give values and description in the enumeration type.
-> Declare a value attribute of Simple type in View Controller.
-> Add a image UI Element and bind it with two attributes(Ctx1 and Ctx2).
Use the code below to get the name of image and further set it :
String vehicleType = wdThis.wdGetContext().currentContextElement().getCtx1();
wdThis.wdGetContext().currentContextElement().setCtx2(vehicleType+ ".jpg");
Go through the [link|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d0e599cc-2862-2b10-54a9-dcf1376b52d7]

How to Upload a File in Bpel Process using JSP

I am trying to upload file in bpel process using front end as a Jsp.
i create the jsp page and i am able to pass the value from jsp to bpel process.
In bpel process i don't know how to pass or assign the specified file name into file adapter for reading the files.
Please help me...
Saravanan

You don't assign the url of the file to it.
To either get the data from the file into the bpel process you could use the url-parameter together with the ora:readFile function....or you could let your web-application upload the file to some location on the server...and on this location you could use the file-adapter together with the polling, to start your bpel process.
