12.2. Sharing Message Resources with JSTL

Problem

You want the JSTL formatting tags (fmt) tags to use the same MessageResources properties file used by Struts.

Solution

        <param-value>path.to.MessageResources
        </param-value>

You define this default resource bundle for your JSTL tags with a web application context parameter. Set the param-name to javax.servlet.jsp.jstl.fmt.localizationContext and the param-value to the same value as the parameter of the message-resources element in your struts-config.xml file.
