Format number in Struts 2 <s:property/> tag

The way more fast

<s:property value="getText('{0,number,#,##0.00}',{summary.total})"/>

Lucky!!

You need to use <s:text/> with <s:param/>.

Property file:

summary.cost= € {0,number,##0.00}

JSP:

<s:text name="summary.cost"> 
    <s:param name="value" value="summary.total"/> 
</s:text>

This answer explains how to use # and 0 in the format mask.

This one is quicker:

<s:property value="getText('struts.money.format', {summary.cost})" />

And in your properties file this:

struts.money.format= {0,number,\u00A4##0.00}

Hope this help
