XSSFWorkbook to InputStream










0















To create an excel the examples are as follows:



XSSFWorkbook workbook = new XSSFWorkbook();
...
FileOutputStream output_file =new FileOutputStream(new File("C:\XXX.xls"));
wb.write(output_file);


I need an InputStream, since I am going to directly send the processed file as an attachment to an email and the mail api asks me for an ImputStream.



How can I get it?

    write to a ByteArrayOutputStream call toByteArray on it - you can then use this in a ByteArrayInputStream - you could also try PipedOuputStream/PipedInputStream - stackoverflow.com/questions/5778658/…
