title: The type java.util.Map$Entry cannot be resolved
body: <p>I've a JSP file which needs the class <code>Map</code>, which belongs to <code>javax.script</code> (if I'm not wrong).</p>
  
  <p>I've imported it, but I'm getting the following error:</p>
  
  <pre><code>The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files
  </code></pre>
  
  <p>After doing a bit of research, I think it's because I need to have a jar file which contains it, but I don't <strong>know how can I find it</strong> (neither to which jar, nor the place to download it).</p>
  
  <p>Could you explain me <strong>how to find it</strong> (as it would be useful for future cases) or provide a link?</p>
  
  <p>Thank you so much</p>
