title: How to set Jasper to use XSSF?
body: <p>In a existing system already use jasper 5.0 and as I know it use poi <strong>HSSF</strong> to generate xls data, but now as the application grow up, the report have a problem with a big count transaction to generate. </p>
  
  <p>I have search for the solution and found POI with <strong>XSSF</strong>. Because jasper use POI HSSF too, I thinking about to use XSSF inside of JASPER. </p>
  
  <p>Is that possible? and how I could do that? I need to use jasper because it's not possible for now to change the existing app.</p>
