Format decimal and date fields

[Michael Mok <mi...@consultech.net.au>]

Hi

Is it possible to use STRUTS to format the display of decimal and date
fields? If so how can I get about doing it.

I have a Order bean which a contain a date field (eg orderdate of type
Calendar) and a decimal field (eg orderamount BigDecimal)

I managed to create an arraylist of orders (Order bean) and use the iterate
tag to loop through to show each order details however, how do I use it to
format the date and decimal field?

TIA

Eg

<jsp:useBean id="orderlist" scope="session" type="java.util.ArrayList"/>

<table>
<!-- process the result set -->
   <struts:iterate id="orderlist" name="orderlist">
   <tr>
   	<td>
   		<struts:htmlProperty name="orderlist" property="orderDescription"/>
   	</td>
   	<td>
   		<struts:htmlProperty name="orderlist" property="orderDate"/>
   	</td>
   	<td>
   		<struts:htmlProperty name="orderlist" property="orderAmount"/>
   	</td>
 </tr>
 </struts:iterate>
</table>

Current versions of the Struts form tags do not do any "smart" conversions like this
for you.  However, upcoming enhancements will let you use a JavaBeans-style
PropertyEditor class to define conversions to and from a text string format for your
bean properties.  Using this, you'd be able to specify the sorts of Locale-sensitive
conversions that you describe here.
