EL will fail in JSTL tags in a JSF2 webapp when you're using the ancient and EOL'ed JSTL 1.0 for some reason.

Make sure that you've installed at least JSTL 1.1 or 1.2. JSTL 1.2 is recommended. First remove jstl.jar and standard.jar from your /WEB-INF/lib, then download jstl-1.2.jar and drop it in /WEB-INF/lib. Finally make sure that you set the XML namespace as follows (with the /jsp path in the URI!):

xmlns:c="http://java.sun.com/jsp/jstl/core"

Use $ instead of #

<c:forEach var="i" begin="1" end="20" step="1" varStatus ="status">
        <c:out value="${i}" /> 
</c:forEach>

<c:forEach> is from JSTL, with JSF you should use <ui:repeat> as Luiggi commented

you are not specifying what exactly does not work when you use it with your map... did you try setting the items of your map/table within the foreach:

<c:forEach items="#{myMap}" var="item">             
  <h:outputText value="#{item.key}" />
  <h:outputText value="#{item.value}" />
</c:forEach>
