Hello All...

I have problem with JSF file uploading.

I have uploaded excel file with ' inputFileUpload' tag of JSF and given value using BEANS as #{myBeans.myFile} to the tag. Now in backbean java file I can't able to get that file so that I can process or parse excel file. I declared it as follows
String inputFile= " #{myBeans.myFile}". But its not working. I don't know whether its right??. I also given getters & setters for 'inputFile' . But when i give direct path of the file like- String inputFile="c:/upload/test.xls" I am able to process that excel file file successfully. I have used POI to parse excel file.

Also I am able to display contents of xls from JSf form in the browser. Although I am getting it on the tomact console. I used following code to parse and display xls file contents.


Can anybody suggest solution to this. Also how to display xls file contents to browser with JSF form.

public String fileSubmit() throws IOException
{

inputFile= "c:/upload/test.xls";


//inputFile="#{attend.inputFile}";

List cellDataList = new ArrayList();



try
{
/*
* Create a new instance for FileInputStream class
*/
FileInputStream fileInputStream = new FileInputStream(inputFile);

/*
* Create a new instance for POIFSFileSystem class
*/

POIFSFileSystem fsFileSystem = new POIFSFileSystem(fileInputStream);

/*
* Create a new instance for HSSFWorkBook Class
*/

HSSFWorkbook workBook = new HSSFWorkbook(fsFileSystem);
HSSFSheet hssfSheet = workBook.getSheetAt(0);

/*
* Iterate the rows and cells of the spreadsheet to get all the data.
*/

Iterator rowIterator = hssfSheet.rowIterator();

while (rowIterator.hasNext())
{
HSSFRow hssfRow = (HSSFRow) rowIterator.next();
Iterator iterator = hssfRow.cellIterator();
List cellTempList = new ArrayList();

while (iterator.hasNext())
{
HSSFCell hssfCell = (HSSFCell) iterator.next();
cellTempList.add(hssfCell);
}
cellDataList.add(cellTempList);
}
}
catch (Exception e)
{
e.printStackTrace();
}


printToConsole(cellDataList);
// List retList=printToConsole(cellDataList);

return "upLoaded";
}

private List printToConsole(List cellDataList)
{
for (int i = 0; i < cellDataList.size(); i++)
{
List cellTempList = (List) cellDataList.get(i);
for (int j = 0; j < cellTempList.size(); j++)
{
HSSFCell hssfCell = (HSSFCell) cellTempList.get(j);

String stringCellValue = hssfCell.toString();
System.out.print(stringCellValue + "\t");




}
System.out.println();


}


return cellDataList;



}





Thanks...
