My client requirement is to upload an Excel File (which is generated from another system). To upload this generated Excel File, I am using Apache POI api. The following jar files are in the classpath of my application.
dom4j-1.6.1
ooxml-schemas-1.0
poi-3.5-FINAL
poi-ooxml-3.5-FINAL
xmlbeans-2.3.0
openxml4j-1.0-beta.jar
I am getting the following exception(using Apache POI3.5)
Exception in thread "main" java.lang.IllegalArgumentException: Your InputStream was neither an OLE2 stream, nor an OOXML stream
at org.apache.poi.ss.usermodel.WorkbookFactory.create(WorkbookFactory.java:65)
at PoiExcelRead.main(PoiExcelRead.java:22)
when my code is
17 public static void main(String[] args) throws IOException, InvalidFormatException {
18 // TODO Auto-generated method stub
19
20 String xlsPath = "d://BOM70914831.xls";
21 InputStream myxls = new FileInputStream(xlsPath);
22 Workbook workBook = WorkbookFactory.create(myxls);
23 }
and I am getting the following exception(using Apache POI3.0)
Exception in thread "main" java.io.IOException: Invalid header signature; read 0x6D78206C6D74683C, expected 0xE11AB1A1E011CFD0

when my code is
17 public static void main(String[] args) throws IOException {

20 String xlsPath = "d://BOM70914831.xls";
21 InputStream myxls = new FileInputStream(xlsPath);
22 HSSFWorkbook wb = new HSSFWorkbook(myxls);
23 }
Please find the sample excel file(

Note: It is working when I open the file using Microsoft Excel and saving it as another file(using File>Save As option from Microsoft Excel Menu)
