Read data from read only xlsm file using Java Apache POI

Question

I'm trying to read data from a read only xlsm using java apache poi, but when I use XSSF workbook it doesn't seem to be able to access the file and HSSF workbooks only work for xls files. My code looks like this:

try {
                FileInputStream file = new FileInputStream(new File("file.xlsm"));
                System.out.println("found file");
                XSSFWorkbook workbook = new XSSFWorkbook(file);
                System.out.println("in workbook");
                XSSFSheet sheet = workbook.getSheet("Shipments");
                System.out.println("got sheet");

The code never reaches the "in workbook" print line and I'm not sure why. Please help!

Answer 1

I copied your code and gave the absolute path of the file, and I was able to get the expected result.

FileInputStream file = new FileInputStream(new File("C:\\Users\\user\\Desktop\\filet.xlsm"));
System.out.println("found file");
XSSFWorkbook workbook = new XSSFWorkbook(file);
System.out.println("in workbook");
XSSFSheet sheet = workbook.getSheet("Shipments");
System.out.println("got sheet");

It seems like a problem with your referencing. Therefore check the way you refer to the files when you try to create the file resource.
