I made a simple jsp that tests the JSTL tag fmt:formatDate:
<jsp:useBean id="now" class="java.util.Date"/>
<fmt:formatDate value="${now}" pattern="dd/MM/yyyy"/>
When access directly through JBoss and struts, it works. When tested through
the JBoss portal, with the struts bridge, it gives this exception:
Error Type java.lang.NullPointerException

Is there something special I have to do in order to use this JSTL? I believe I
have the latest versions of all the relevent JARs.
