Upload and Reading Excel File in Web Dynpro

Hi all,
I have a requirement in my application( in 04s), where in, i need to upload an excel from a client through a web dynpro application(using fileupload UI) and read each and every the content of that excel file in web dynpro and process the data accordingly.
The format of the excel is fixed and pre-defined.
I went through a lot of blogs, but could not find a direct and exact solution to this requirement.
Please help me.
Looking forward to your contribution
Thank you,

Error While uplaoding a EXCEL file in Web dynpro - HR_KR_XSTRING_TO_STRING

Hi,
I am getting an error while uploading an excel file in web Dynpro application. i am using the HR_KR_XSTRING_TO_STRING this function. I am getting the following error message 'Unable to interpret as a number'.

First of all, are you sure you know what you are working with here. If this is standard Excel file in the Microsoft binary/propriatery format there is not function module or class in ABAP that can magically just transform this to a character string. You should search the forums as this has been discussed extensively. On that topic, please also do not post duplicate threads. I have already locked your other thread with the same basic question.
Instead of the binary/propriatery format of Excel, the file should be saved on the client as a text based format - like XML or Text Tab Delimited. You can then use several different options on the server to convert the XSTRING to STRING and process the content (becuase it was text based to begin with). You could use CL_BCS_CONVERT, the function modules in the function group SCMS_CONV, or the class CL_ABAP_CONV_IN_CE.

Reading contents of uploaded excel file in web dynpro java

Hi All.
I am aware how to provide facility to upload files in web dynpro java. But my requirement is that on uploading a particular file (for eg. an excel file having 10 columns), I need to read the contents of that file and store it in a table in R/3.Can anyone suggest a way how I can read the contents of the uploaded file?
Thanks and Regards,
Saurabh.

Hi.
I am having the following requirement : I have a FileUpload UI element where user clicks Browse button, selects a file from the local system and presses a Upload button. Upon pressing Upload, the name of the selected file and the contents of the file should be shown.
In the View context, I have two value attributes: FileName of type String and FileResource of type binary.
This is the code that I have in the Upload button action handler :
public void onActionUpload(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionUpload(ServerEvent)
    IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(
             IPrivateReadExcelView.IContextElement.FILE_RESOURCE);
    IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType)attributeInfo.
             getModifiableSimpleType();
    IPrivateReadExcelView.IContextElement element = wdContext.createContextElement();
    String fname = binaryType.getFileName();
    wdComponentAPI.getMessageManager().reportSuccess("File selected - "+fname); //Statement 1
     try {
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    // Statement 2
          InputStream in = new FileInputStream(fname);
          HSSFWorkbook wb = new HSSFWorkbook(in);
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    //Statement 3
          int sheetsNo = wb.getNumberOfSheets();
          for (int i=0;i<sheetsNo;i++) {
               HSSFSheet sheet = wb.getSheetAt(i);
               Iterator rowsNo = sheet.rowIterator();
               while(rowsNo.hasNext()) {
                    HSSFRow rows = (HSSFRow)rowsNo.next();
                    Iterator colsNo = rows.cellIterator();
                    while(colsNo.hasNext()) {
                         HSSFCell cell = (HSSFCell)colsNo.next();
                         wdComponentAPI.getMessageManager().reportSuccess("File uploaded" +
                              "successfully");
                         if(cell.getCellType()==1) {
                              wdComponentAPI.getMessageManager().reportSuccess("00000"+
                                   cell.getStringCellValue());
                         else if(cell.getCellType()==0) {
                              String str=""+cell.getNumericCellValue();
                              wdComponentAPI.getMessageManager().reportSuccess("11111"+str);
     catch(Exception e) { wdComponentAPI.getMessageManager().raisePendingException();
    //@@end
On pressing Upload button, name of selected file is being shown(Statement 1). I am also getting Statement 2 in the output. However I am not getting Statement 3 onwards.
Where am I going wrong? Can anyone shed some light on this?

Regarding Copying of Data From Excel file to Web Dynpro Java Table

Hi
Can any body give Suggestions that is how to copy or import Row and Column Values in the Excel file to the Java Web Dynpro Table
Regards
Chandran S

Hi,
First u should include jxl.jar API in ur classpath.
ind a Resource variable to FileUpload UI. Then from the Fileupload UI, u can get the Sheet variable as
InputStream fis=wdContext.currentFileUploadElement().getResource().read(true);
Workbook wb=Workbook.getWorkbook(fis);
Sheet sh=wb.getSheet(0);
This can be easily read to a table by
for(int i=14;i<34;i++)
     String bId=sh.getCell(2,i).getContents();
     String cId=sh.getCell(3,i).getContents();
     String subj=sh.getCell(4,i).getContents();
                IPrivate<View>.I<Table>Element el=wdContext.node<Table>().create<Table>Element();
                wdContext.node<Table>().addElement(el);
                el.setBID(bid);
                el.setCID(cid);
                el.setSUB(subj);
This example reads the excel from row 13 to 32 and column 3 to 5 and uploaded to a table

Download Excel file through Web dynpro with no windows open?

Can we have a web dynpro application that just returns an Excel file in the response with no open windows? Similar to a java servlet that is used to download a Excel file?
This basically means that I cannot use wdComponentAPI.getWindowManager().createNonModalExternalWindow()
Java Servlet Code
HttpSession session = request.getSession();      // get a handle on the session id
response.setContentType("application/download");
response.setHeader("Content-Disposition", "filename=RTIS_Report.xls");
PrintWriter out = null;
out = response.getWriter();
String report = request.getParameter("REPORT");
JCO.Table lines = download(request, session, report);
for (int i = 0; i < lines.getNumRows(); i++) {
     lines.setRow(i);
     String content = lines.getString("LINES") + "\n";
     out.write(content);
     out.flush();
out.flush();
out.close();

Hi,
I think you can use IWD Cached Web Resource to achieve this..
See the below code FYI..
public void downloadToExcel( )
    String fileName = "Customer" + ".xls";
     IWDCachedWebResource cachedExcelResource = null;
     try
          File f = new File("Customer.xls");
          WritableWorkbook workbook =   Workbook.createWorkbook(f);
          WritableFont black = new WritableFont(WritableFont.createFont("Trebuchet MS"),WritableFont.DEFAULT_POINT_SIZE,WritableFont.BOLD,false,UnderlineStyle.SINGLE,Colour.BLACK);
          WritableCellFormat blackFormat = new WritableCellFormat(black);
          WritableFont blue = new WritableFont(WritableFont.createFont("Trebuchet MS"),WritableFont.DEFAULT_POINT_SIZE,WritableFont.NO_BOLD,false,UnderlineStyle.NO_UNDERLINE,Colour.BLUE);
          WritableCellFormat blueFormat = new WritableCellFormat(blue);
          WritableSheet sheet = workbook.createSheet("Customer", 0);
               Label label;
               String[] header={"Corporate Code","Batch ID"};
               for (int i=0;i<2;i++)
                    label = new Label(i,0,header<i>.toString(),blackFormat);
                    sheet.addCell(label);
               WritableCellFormat integerFormat = new WritableCellFormat(NumberFormats.INTEGER);
               jxl.write.Number number;
               // Reading the contents
               for(int i=0;i<wdContext.nodeVn_DownloadToExcel().size();i++)
                    String strCorpName = wdContext.currentContextElement().getVa_CorpCode();
                    String strBatchID =     wdContext.nodeVn_DownloadToExcel().getVn_DownloadToExcelElementAt(i).getVa_BatchID();
                    label = new Label(0,i+1,strCorpName,blueFormat);
                    sheet.addCell(label);
                    label = new Label(1,i+1,strBatchID,blueFormat);
                    sheet.addCell(label);
               workbook.setColourRGB(Colour.LIME, 0xff, 0, 0);
               workbook.write();
               FileInputStream excelCSVFile = new FileInputStream(f);
               IWDCachedWebResource cachedWebResource = null;
               if (excelCSVFile!= null)
                    cachedWebResource = WDWebResource.getWebResource(excelCSVFile, WDWebResourceType.getWebResourceType("xls","application/ms-excel"));
               cachedWebResource.setResourceName(fileName);
          cachedExcelResource = cachedWebResource;
          wdContext.currentContextElement().setVa_DownloadToExcel(cachedExcelResource.getURL());
          workbook.close();
     catch (Exception ex)
          wdComponentAPI.getMessageManager().reportException("Error in Excel Download"+ex.getMessage(),false);

Upload and read binary files

I have created ADF form with input file item for initiator human task ( to upload a binary file)
In the second form, I want see link of the file uploaded and I want open the file in other window ( to see the content of the binary file)
How can I do?
Thanks Elena

Azazel,
Looks like you are just being an over achiever. There are VI's specifically written for reading and writing binaries. I would guess that the VISA timeout is caused by the way you are calculating the size of the file. Since it is too big the VISA session will time out. See attached example for the easy way to do this.

File upload and download in server through web Dynpro

Hai all,
         i want to store one document in SQL Server 2000 through Webdyn pro. I inserted
one document through java into SQL Server 2000 using the following method which name is
insertFile(...).
void insertFile(FileDBTransfer fdb, Connection cn, String FileName)throws IOException, FileNotFoundException, SQLException
          int FileLength;
          FileInputStream fis;
          PreparedStatement pstmt;
          int last=FileName.lastIndexOf("/");
          String docname=FileName.substring(last+1,FileName.length());
          fis = fdb.getFileInputStream(FileName);
          FileLength= fdb.getFileLength(FileName);
          pstmt = cn.prepareStatement("insert into ReportArchive values(?,?)");
          pstmt.setString(1,docname);
          pstmt.setBinaryStream(2, fis, FileLength); //method to insert a stream of bytes
          pstmt.executeUpdate();
     }// end insertZipFile
     Here i have given file name like "c:\test\test.pdf" it's work fine.
     My J2EE server is running different machine and my Netweaver is another machine.
If both server and IDE in same machine it's work fine. But both are in different machine,
i have some problems.
     If i try like this server always go and check his own path, not client machine
so it will error like "given source not found". So if i get client machine's path
then i will store easily into SQL Server 2000.
     Whenever i run, it should check the client machine path instead of server path.
Thanks in advance,
K.Saravanan.

Hi Saravan,
Data
Determines the data drain, that is, the location of the data, of the file to be uploaded in the context. The system can only read this data value.
fileName
Gives exact filename
Refer IWDFileUpload also

Upload file in Web Dynpro and add to Workflow container as SOFM object

Hi!
I have a Web Dynpro for ABAP application that should send attachments of uploaded files to a workflow container. I have already managed to do this, and it works fine for TXT files, but when I try to attach a WORD (.DOC) file the file looks corrput when I open it from the SAP inbox.
When uploading files in Web Dynpro it is as an XSTRING. I have tried out the following alternatives regarding convertion of the XSTRING before it is inserted in the SOFM object:
1) Convert from XSTRING to STRING using codepage 4110.
Then it is split into a string table of 255 chars
2) Convert from XSTRING to STRING using codepage 4102
Then it is split into a string table of 255 chars
3) Convert from XSTRING to BINARY format
I use function module 'SWL_SOFM_CREATE_WITH_TABLE'
and then swf_create_object lr_sofm 'SOFM' ls_sofm_key.
before I call some macros to fill the container.
Anyone else who have tried to do this with success? I'm greatful for any help.
Regards, Tine

Hi,
I had the same problem in the last days and finally I got a quite simple solution:
I had a look at the FM SWL_SOFM_CREATE_WITH_TABLE an noticed that it calls another FM (SO_DOCUMENT_INSERT_API1) which has a tables parameter for HEX data and is actually able to create a SOFM object from HEX data.
I simply copied SWL_SOFM_CREATE_WITH_TABLE as a customer FM and applied a few changes to make it accept HEX data:
First I added a new table parameter in the interface which gets the HEX data from the calling application (uploaded data using BIN format):
OBJECT_CONTENT_HEX     LIKE     SOLIX
Here is the code of the FM (I marked all additional and changed lines with a comment):
function z_test_sofm_create_with_table .

The returned SOFM key I added to a container element. The element refers to event parameter of type OBJ_RECORD in my ABAP OO Class
Using this function I was able to raise an event by using Method cl_swf_evt_event=>raise
that invoked a workitem containing an Excel-File i had uploaded as binary file and passed to the FM z_test_sofm_create_with_table as document type 'XLS'.
In the woritem preview when clicking on the attachment the file was opened directly in Excel.
Actually the new lines for calculation the file size is not yet quite correct. At first glance it does not seem to cause any trouble, but I will stll check that. In FM SO_OBJECT_INSERT the size is again checked and calculated if initial, so leaving size initial might also be an option.
I hope this helps anyone having a similar issue.

Import data from excel/csv file in web dynpro

Hi All,
I need to populate a WD table by first importing a excel/CSV file thru web dynpro screen and then reading thru the file.Am using FileUpload element from NW04s.
How can I read/import data from excel / csv file in web dynpro table context?
Any help is appreciated.
Thanks a lot

Hi,
Here are the basic steps needed to read data from excel spreadsheet using the Java Excel API(jExcel API).
jExcel API can read a spreadsheet from a file stored on the local file system or from some input stream, ideally the following should be the steps while reading:
Create a workbook from a file on the local file system, as illustrated in the following code fragment:
          import java.io.File;
          import java.util.Date;
          import jxl.*;
         Workbook workbook = Workbook.getWorkbook(new File("test.xls"));
On getting access to the worksheet, once can use the following code piece to access individual sheets. These are zero indexed - the first sheet being 0, the second sheet being 1, and so on. (You can also use the API to retrieve a sheet by name).
          Sheet sheet = workbook.getSheet(0);
After getting the sheet, you can retrieve the cell's contents as a string by using the convenience method getContents(). In the example code below, A1 is a text cell, B2 is numerical value and C2 is a date. The contents of these cells may be accessed as follows
Cell a1 = sheet.getCell(0,0);
Cell b2 = sheet.getCell(1,1);
Cell c2 = sheet.getCell(2,1);
String a1 = a1.getContents();
String b2 = b2.getContents();
String c2 = c2.getContents();
// perform operations on strings
However in case we need to access the cell's contents as the exact data type ie. as a numerical value or as a date, then the retrieved Cell must be cast to the correct type and the appropriate methods called. The code piece given below illustrates how JExcelApi may be used to retrieve a genuine java double and java.util.Date object from an Excel spreadsheet. For completeness the label is also cast to it's correct type. The code snippet also illustrates how to verify that cell is of the expected type - this can be useful when performing validations on the spreadsheet for presence of correct datatypes in the spreadsheet.
String a1 = null;
Double b2 = 0;
Date c2 = null;
                    Cell a1 = sheet.getCell(0,0);
                    Cell b2 = sheet.getCell(1,1);
                    Cell c2 = sheet.getCell(2,1);
                    if (a1.getType() == CellType.LABEL)
                       LabelCell lc = (LabelCell) a1;
                       stringa1 = lc.getString();
                     if (b2.getType() == CellType.NUMBER)
                       NumberCell nc = (NumberCell) b2;
                       numberb2 = nc.getValue();
                      if (c2.getType() == CellType.DATE)
                        DateCell dc = (DateCell) c2;
                        datec2 = dc.getDate();
                       // operate on dates and doubles
It is recommended to, use the close() method (as in the code piece below)   when you are done with processing all the cells.This frees up any allocated memory used when reading spreadsheets and is particularly important when reading large spreadsheets.
          // Finished - close the workbook and free up memory
          workbook.close();
The API class files are availble in the 'jxl.jar', which is available for download.

Uploading excel files into Web UI

We are following the blog http://wiki.sdn.sap.com/wiki/display/CRM/CRMWebUI-UploadingdatafromExcelfiles
to upload excel files into Web UI.
The problem which we are facing is that the values are not getting populated in the text are and in the
event handler EH_ONSERVEREVENT, no values are being populated in lt_items table.
It would be great if someone could help us with this.

Hi Nidhi,
I have tried the blog but due to some reason, could not get it worked out.
But, If U are ok to use CSV input files, instead of excel, U can use the standard component "GS_FILE_UPLOAD" as a popup and upload the files into the required assignment blocks.

File Visibility in uploading the file using web DynPro java

hello,
i have gone through the tutorial " uploading & downloading the file using web DynPro java".
the upload functionalty is working fine. but i need to know thw path where these files are getting uploaded ??
Waiting for the reply..

Viren Gupta

Hi Viren,
Are you are refering to the below tutorial for upload and download:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b0e10426-77ca-2910-7eb5-d7d8982cb83f?QuickLink=index&overridelayout=true
If yes, then answer is that the file is stored in the context of the application only as "com.sap.ide.webdynpro.uielement-definitions.Resource" object. Please read through the tutorial to understand the full process.
WD doesn't really upload to server automatically unless there is any explicit code written. All it does is to store the file in a temp context which you can access and write your own code to store it in a particular location.
