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?

Hi,
You are trying to read file wrong way. In the tutorial of Java Excel Api: "JExcelApi can read an Excel spreadsheet from a file stored on the local filesystem or from some input stream.". You are trying to read from file system. So you must get file input stream then you can read it. Please search forums KM file read.

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);

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

ADF 11g : Live messages about status/errors while uploading a Excel file

Hi,
Im using ADF 11.1.1.2. In the ADF application, there is a module where the user will upload a excel sheet with lot of data(50,000 lines) in multi sheets. We are validating the data against certain business validations and inserting this data into Database tables once all the validations are successful. In case any validation errors are there we write them into a log file and send it to the user.
Now the requirement we are stuck with is to show the validation messages/errors on a screen while the upload is in progress. The messages are to be live i.e in case now the code is validating row 10 and there is a error then that error message with row number is to be displayed on the screen and when the validation process continues with row 11, we need to show message saying 'Row 11 validation in process...'.
thanks,
Manasa.

For this you can use a progress bar together with an DefaultBoundedRangeModel where you run the validation in a thread. This thread put the messages somewhere where the UI picks them up.
On the other side, your requirement is hard to do. I did some math: 50,000 records to validate and you want to show a message for each row; If each message need only a second you end up with more then 12 hours of work. Nobody will stare at the screen for that long. If the validation takes longer then a second it gets worse. If you show the message for less then a second, the user can read it anyway, so you don't need to show a message for every row.
We do this kind of work in the background. The user has to ask for the progress of the process and can look at errors reported so far. This way the user can do something else even if the job runs for a long time.

Error while opening an excel file via labview

i don't know why i get this message,then the excel won't open at all

It appears that the New Report .vi only accepts the .xlt template format and not .xltx as one would commonly expect. I am currently working to determine for sure that this is the case, but it does run (mostly) properly on my end if you make that change.
When I say mostly, I mean there are a couple other minor issues with your code. First the first frame of your sequence structure is really accomplishing anything. If your intent is to open a reference to the excel template, there is no need because the New Report .vi does it automatically.
Second, you will need a file path of some sort wired in to your Save Report to File .vi or else you will get a different error message after fixing the .xlt issue. I am currently researching whether this should be marked as a required terminal instead of recommended so that it not being wired would result in a broken run arrow rather than an error.
Let me know if these suggestions resolve your issue, or if I can provide further input on what you are doing in your first frame. I will touch base again once I determine whether these are expected behaviors or bugs.

Firstly, Thanks for Your quick Response, Thomas.
Even though what ever may be the file name I am passing either info.xml or Info.xls , In error info.xls is coming.
Kindly provide me an alternative on this XML doesn't seem like it would match the 'application/vnd.ms-excel'.

Similarly, It is not considering the UTF-8 / UTF-16 for xml.........same result is appearing in the output.

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
Aakash

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.
Regards
Raghu
