title: JSP Expression Language get parameter
body: <p>I am trying to get a <code>String</code> parameter <code>"username"</code> from the <code>request</code> with <strong>Expression Language</strong>.
  I've done some research, but couldn't find a way to do so, I would like something similar to <code>${pageContext.request.parameter.username}</code></p>
  
  <p>How get a specific request parameter, using only expression language?</p>
