title: Which jar files do I need to read and write values from a Excel File using POI from Java?
body: <p>I want to read values and write values from an Excel file or .xls file using POI from Java. I don't need the source code; I can write that.</p>
  
  <p>I have already looked around on the <a href="http://poi.apache.org" rel="nofollow noreferrer">developers site</a>, but there were lots of files. Which jar file(s) do I need to download so that <code>import org.apache.poi.hssf.usermodel.*;</code> will work?</p>
