    copied!<p>Just the same way as you would do in normal Java code.</p> <pre><code>for (Map.Entry&lt;String, String&gt; entry : countries.entrySet()) { String key = entry.getKey(); String value = entry.getValue(); // ... } </code></pre> <hr> <p><strong>However</strong>, <em>scriptlets</em> (raw Java code in JSP files, those <code>&lt;% %&gt;</code> things) are considered a <a href="https://stackoverflow.com/questions/3177733/howto-avoid-java-code-in-jsp-files/3180202#3180202">poor practice</a>. I recommend to install <a href="http://download.java.net/maven/1/jstl/jars/jstl-1.2.jar" rel="noreferrer">JSTL</a> (just drop the JAR file in <code>/WEB-INF/lib</code> and declare the needed <a href="http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/" rel="noreferrer">taglibs</a> in top of JSP). It has a <a href="http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/c/forEach.html" rel="noreferrer"><code>&lt;c:forEach&gt;</code></a> tag which can iterate over among others <code>Map</code>s. Every iteration will give you a <a href="http://java.sun.com/javase/6/docs/api/java/util/Map.Entry.html" rel="noreferrer"><code>Map.Entry</code></a> back which in turn has <code>getKey()</code> and <code>getValue()</code> methods.</p> <p>Here's a basic example:</p> <pre class="lang-xml prettyprint-override"><code>&lt;%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %&gt; &lt;c:forEach items="${map}" var="entry"&gt; Key = ${entry.key}, value = ${entry.value}&lt;br&gt; &lt;/c:forEach&gt; </code></pre> <p>Thus your particular issue can be solved as follows:</p> <pre class="lang-xml prettyprint-override"><code>&lt;%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %&gt; &lt;select name="country"&gt; &lt;c:forEach items="${countries}" var="country"&gt; &lt;option value="${country.key}"&gt;${country.value}&lt;/option&gt; &lt;/c:forEach&gt; &lt;/select&gt; </code></pre> <p>You need a <code>Servlet</code> or a <code>ServletContextListener</code> to place the <code>${countries}</code> in the desired scope. If this list is supposed to be request-based, then use the <code>Servlet</code>'s <code>doGet()</code>:</p> <pre><code>protected void doGet(HttpServletRequest request, HttpServletResponse response) { Map&lt;String, String&gt; countries = MainUtils.getCountries(); request.setAttribute("countries", countries); request.getRequestDispatcher("/WEB-INF/page.jsp").forward(request, response); } </code></pre> <p>Or if this list is supposed to be an application-wide constant, then use <code>ServletContextListener</code>'s <code>contextInitialized()</code> so that it will be loaded only once and kept in memory:</p> <pre><code>public void contextInitialized(ServletContextEvent event) { Map&lt;String, String&gt; countries = MainUtils.getCountries(); event.getServletContext().setAttribute("countries", countries); } </code></pre> <p>In both cases the <code>countries</code> will be available in <a href="http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSPIntro7.html" rel="noreferrer">EL</a> by <code>${countries}</code>.</p> <p>Hope this helps.</p> <h3>See also:</h3> <ul> <li><a href="https://stackoverflow.com/questions/2148658/iterate-over-elements-of-list-and-map-using-jstl-cforeach-tag/">Iterate over elements of List and Map using JSTL &lt;c:forEach&gt; tag</a></li> <li><a href="https://stackoverflow.com/questions/2141464/how-to-iterate-over-a-nested-map-in-cforeach/">How to iterate over a nested map in &lt;c:forEach&gt;</a></li> <li><a href="https://stackoverflow.com/questions/2117557/how-to-iterate-an-arraylist-inside-a-hashmap-using-jstl/">How to iterate an ArrayList inside a HashMap using JSTL?</a></li> <li><a href="https://stackoverflow.com/questions/3468150/using-special-auto-start-servlet-to-initialize-on-startup-and-share-application">Using special auto start servlet to initialize on startup and share application data</a></li> </ul>
