What is the cleanest way to display a java.util.Calendar object in JSF?

For others and @seangates: You CAN apply a pattern if using the Calendar object. E.g.

<h:outputText value="#{bean.calendar.time}" styleClass="date">
    <f:convertDateTime pattern="EEEE, MMMM d yyyy" />
</h:outputText>
&nbsp;
<h:outputText value="#{bean.calendar.time}" styleClass="time">
    <f:convertDateTime pattern="hh:mm" />
</h:outputText>

Use Calendar's own getter Calendar#getTime(). It returns a Date. Then you can use <f:convertDateTime> the usual way.

<h:outputText value="#{bean.calendar.time}">
    <f:convertDateTime type="both" dateStyle="long" />
</h:outputText>
