title: import .xls files to mysql in java servlet
body: <p>I have a folder of 300+ xls files. The structure of this files is the same, but data is different. So I need to import this data to mysql table using servlets.
  I think there are few stages:</p>
  
  <ol>
  <li>Load a folder with files to server</li>
  <li>Convert files to .csv</li>
  <li>Import files one by one to mysql</li>
  </ol>
  
  <p>But how can I implement this mechanism technically using servlets?</p>
  
  <p>Thanks</p>
