* I get an "Couldn't find template: /home/mats/myapp/metadata/templates/struts_form.xdt" when I run "ant setup test-all" after specifying "jsf" as web framework when running "ant new".

* Why is the JSTL keyword 'empty' not working all the time?

;:''The empty keyword (pre JSP 2.0), only worked on java.util.List, java.util.Map, on Strings and arrays. Collections like java.util.Set were not supported. If you are using pre JSP 2.0 and want to test whether a Set is empty or not use: {{{

<c:if test="${mycollection['empty']}">.

}}}

The most reliable workaround to this problem I have found, is to use this notation:

{{{

<c:forEach items="${mycollection}" var="element" varStatus="rowNum">

<c:if test="${rowNum.count==1}">

<table>

<tr> <th> Value Header </th> </tr>

</c:if>

<tr>

<th>

<c:out value="${element.value}"/>

</th>

</tr>

<c:if test="${rowNum.last}">

</table>

</c:if>

</c:forEach>

}}}

This [article|http://weblogs.java.net/blog/mister__m/archive/2003/11/crazy_jstl_when.html] explains this in more detail. If you are using tomcat 5, this supports JSP 2.0 so you will not experience

this problem.
