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

We开发者_如何学JAVA have an object with java.util.Calendar objects. We would like to display the data on a JSF page (preferably in the same format we have for java.util.Date objects). It seems like there should be some clean way to do this other than creating a wrapper class just to convert the Calendar to a Date.

What is the cleanest way to display the date/time held in a java.util.Calendar in a JSF page?

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>

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>

If you need futher Text:

<h:outputFormat
    value="#This my date: {0,date,long}">
    <f:param value="#{bean.calendar.time}" />
</h:outputFormat>
