the excel file

Error occur when i deal excel 2003 files with poi.
(btw: the hssf.xls file is created by ms office 2003 directly.

and i use FileFormatConverters.exe Compatibility Pack for opening office2007 files.

now i see FileFormatConverters.exe is the right reason why this error occur.
please see the picture attached.

The code like this: (hssf.xls as attached.)
import java.io.FileInputStream;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;

public class PoiTest {
	public static void main(String[] args) {
		FileInputStream in;
		try {

			in = new FileInputStream("e:/hssf.xls");

			POIFSFileSystem f = new POIFSFileSystem(in);
			HSSFWorkbook wb = new HSSFWorkbook(f);


		} catch (Exception e) {




The exception as bellow:
