title: Why there is an error in import javax.servlet.*?
body: <p>I am using JavaSE6 and Eclipse, there is an error in the line </p>
  
  <pre><code>import javax.servlet.*
  </code></pre>
  
  <p>It seems there is no jar for this import.</p>
  
  <p>How to fix it? Install anything, use Eclipse EE or add some dependency in Maven?</p>
