Problemas de codificación usando tiles

Puede ser útil añadir el siguiente código al web.xml, en el caso de que tengamos problemas con los acentos, para corregir problemas u obtener información de ellos:

<web-app>
    ...
    <jsp-config>
        <jsp-property-group>
            <url-pattern>*.jsp</url-pattern>
            <page-encoding>UTF-8</page-encoding>
            <trim-directive-whitespaces>true</trim-directive-whitespaces>
        </jsp-property-group>
    </jsp-config>    
</web-app>
