I should add that I think the determining factor is not the file size, it is the
number of rows. I can easily load a file with more total kb but fewer rows.
The file that will not load has over 1000 rows.

> HSSFWorkbook workbook;
> File inputFile = new File("big_test.xls");
> try {
> InputStream fileIn = new FileInputStream(inputFile);
> fileIn = new BufferedInputStream(fileIn);
> workbook = new HSSFWorkbook(fileIn);
> fileIn.close();
> } catch (FileNotFoundException ex) {
> } catch (IOException ex) { }
> }
>
> }
>
> And for the eventmodel, I am using the example from the HSSF howto homepage.
> It gets this far:
>
> Encountered workbook
> New sheet named: Sheet1
> New sheet named: Sheet2
> New sheet named: Sheet3
>
> And then it hangs the same way the usermodel did.
> I have also had this problem on a Windows XP box, and I've tried it with what
> appears to be a recent CVS build (poi-2.1-20050221). It never works. What is
> going on here?
