How to fill in Excel file using java

Question

I have the following code to fill in the Excel file, with information that I get from the Internet using Jsoup.

package knvbj;

import java.io.FileInputStrea         


        

Answer 1

For me this appears to have been caused by a timeout in AWS, closing the output stream. the error message is not helpful and misleading. That's the best I could come up with so far from available info.
