hssf upload file issue

["Narasimhan, Shyamala" <Sh...@owens-minor.com>]

Hi

I am trying to convert (to hssf) an xls file uploaded through struts on a
weblogic server.. the file gets converted if I use a standalone java
application but fails when uploaded through the web. The file contains more
than 2000 rows. This is the code that converts the file

 

      // get the file from form

        FormFile prodFile = uploadForm.getFile();

        String fileName = prodFile.getFileName();

        log__.info("file name = " + fileName + "... fileSize = " +
prodFile.getFileSize());

        POIFSFileSystem fs = new POIFSFileSystem(prodFile.getInputStream());

 

        HSSFWorkbook wb = null;

        try {

          wb = new HSSFWorkbook(fs);

        }

        catch (Exception e){

          e.printStackTrace();

        }

 

This is the error that I am getting

java.lang.NegativeArraySizeException
