The file appears twice on your computer, because your servlet code saves the *.xlsx file to disk before sending it to your browser. That's the behavior your chose in your code.

Remark however, that file in your code is a relative path, so the folder you write it is the working directory (according to the OS) of your server. The value of the working directory is not defined in the Servlet Specification and may vary from system to system.

A better solution would be:

  • either don't write any file at all and write your data directly to ServletResponse#getOutputStream(),
  • or write the file to the Servlet's temporary directory, which you can obtain through (File) servletContext.getAttribute(ServletContext.TEMPDIR). E.g. you can replace your file variable with:
final File file = new File((File) servletContext.getAttribute(ServletContext.TEMPDIR), filename);

i think the this problem can be sovled, just by fixing the place you want to created the file

String FILE_EXTENSION = ".xlsx"; DateFormat df = new SimpleDateFormat("yyyyMMddhhmmss"); filename = "SearchPayment_Transactions_" + df.format(new Date()) + FILE_EXTENSION; File file = new File(path any fixed directory like temp\filename);

As long as you specify the path where you want to generate the file then it will generating only in tht directory. PLease make proper permission is given to path to generate file, and this will solve your issue.
