title: Using JSTL how to "put" a value into a HashMap
body: <p>I'm looking to set the key value pairing of a HashMap using JSTL only. Is this possible?</p>
  
  <p>I know how to retrieve the key value pairs, but I haven't found a way to set them. </p>
  
  <p>Any help would be appreciated. </p>
  
  <p>Example of retrieving HashMap key/value pairs using JSTL:</p>
  
  <pre><code>&lt;c:forEach var="hash" items="${myHashMap}"&gt;             
      &lt;c:out value="${hash.key}" /&gt;
      &lt;c:out value="${hash.value}" /&gt;
  ...
  </code></pre>
