    copied!<p>I have a Hashtable&lt;Integer, Sport> called sportMap and a list of sportIds (List&lt;Integer> sportIds) from my backing bean. The Sport object has a List&lt;String> equipmentList. Can I do the following using the unified EL to get the list of equipment for each sport?</p> <pre><code>&lt;h:dataTable value="#{bean.sportIds}" var="_sportId" &gt; &lt;c:forEach items="#{bean.sportMap[_sportId].equipmentList}" var="_eqp"&gt; &lt;h:outputText value="#{_eqp}"&gt;&lt;/h:outputText&gt; &lt;br/&gt; &lt;/c:forEach&gt; &lt;/h:dataTable&gt; </code></pre> <p>I get the following exception when trying to run this JSP code.</p> <pre> 15:57:59,438 ERROR [ExceptionFilter] exception root cause javax.servlet.ServletException: javax.servlet.jsp.JspTagException: Don't know how to iterate over supplied "items" in &amp;lt;forEach&amp;gt;</pre> <p>Here's a print out of my environment</p> <pre> Server: JBossWeb/2.0.1.GA Servlet Specification: 2.5 JSP version: 2.1 JSTL version: 1.2 Java Version: 1.5.0_14 </pre> <p>Note: The following does work using a JSF tag. It prints out the list of equipment for each sport specified in the list of sportIds. </p> <pre><code>&lt;h:dataTable value="#{bean.sportIds}" var="_sportId" &gt; &lt;h:outputText value="#{bean.sportMap[_sportId].equipmentList}"&gt; &lt;/h:outputText&gt; &lt;/h:dataTable&gt; </code></pre> <p>I would like to use the c:forEach tag. Does anyone know if this is possible? If not, anyone have suggestions? In the end I want a stacked list instead of the comma seperated list provided by equipmentList.toString(); (Also, don't want to override toString()).</p>
