Upload the Excel shet through BPM

Question

Hi,
I have a kind of functionality that client user can upload a excel sheet and create the instance based on the excel sheet records. So from the JSP side I am uploading the file and I have given the file type as a BINARY, then I am able to check the file. Length(). But if I am using Java.Io.File or Fueog.Io.File then this value is assigned to NULL
So I have done coding like this.
Binary io = adhocCreation.attachment;
logMessage("file length is = " + Binary(data : io).length());
ByteArrayInputStream bis = ByteArrayInputStream(arg1 : io);
logMessage("bis is = " + bis);
InputStream s = bis;
FileOutputStream outStream = FileOutputStream(arg1 : Fuego.Server.homeDir + "check.xls");
outStream.write(arg1 : io);
outStream.flush();
logMessage("outStream is = " + outStream);
ExternalClasses.Jxl.Write.WritableWorkbook workBook = Workbook.createWorkbook(os : outStream);
logMessage("numberOfSheets are " + workBook.numberOfSheets);
ExternalClasses.Jxl.Write.WritableSheet writableSheet = workBook.getSheet(arg1 : 0);
logMessage("writableSheet = " + writableSheet);
Cell[] cells = writableSheet.getRow(arg1 : 0);
if (cells != null || cells.length() == 0) {
logMessage("result2 = " + cells[0].contents);
And getting the output like this:
file length is = 30208
bis is = java.io.ByteArrayInputStream@35834c
outStream is = java.io.FileOutputStream@13efefe
numberOfSheets are 0
but what ever the file I am uploading that is having 3 sheets on excel sheet
any idea why it is not able to read that.
Thanks

Answer 1

I'm trying to move data from excel into an Oracle forms field. This involves coping 2 columns of data cells in excel and pasting it into an Oracle forms field. I can get the date pasted into the Oracle forms field but there is a invisible character that separates the 2 columns of data coming from Excel. I do not know what this character is but it is causing the error 'Line 1 is invalid. Check forms'.
Any ideas how to get pass this?
Thank you
