I've never used the Struts Adapter, so I can't offer much advice. I
typically use JSTL and with the displaytag. Since this is the
default, it's easy to setup. Just add the following to your web.xml.
<context-param>
<param-name>javax.servlet.jsp.jstl.fmt.localizationContext</param-name>
<param-value>ApplicationResources</param-value>
</context-param>
