title: save file on server, java web application
body: <p>from my web application (vaadin) I generate XML files and want to store these files on the server. I did:</p>
  
  <pre><code>context.getHttpSession().getServletContext().getRealPath("/");
  </code></pre>
  
  <p>I run the web app on tomcat and managed to save the file to the app folder under</p>
  
  <pre><code>.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/my_app_folder/
  </code></pre>
  
  <p>on the same level with META-INF, WEB-INF and VAADIN folder. If I want to save the file on server storage and save the path of the file on the database, where should I save the files? Thank you</p>
