title: Convert JSP to HTML
body: <p>Is there any way to convert a jsp file to html?
  The goal is that the jsp files have a lots of tags, and the real time parsing is too slow, so we want to generate simple statis html files that easy and fast to serve. </p>
  
  <p>In my mind, when the server starts, something generates the static html files, and we only refer to these files in the browser.</p>
