change theme on a per-page basis
The default theme is passed to the page through a theme variable. To change the theme for a page, use the set tag to change the theme variable. The variable can be changed using a static value or property.
Change to the "simple" theme.
<s:set name="theme" value="'simple'" scope="page" />
Change to the theme name indicated by the myTheme property.
<s:set name="theme" value="%{myTheme}" scope="page" />
Themes can be selected using several different rules, in this order:
1. The theme attribute on the specific tag
2. The theme attribute on a tag's surrounding form tag
3. The page-scoped attribute named "theme"
4. The request-scoped attribute named "theme"
5. The session-scoped attribute named "theme"
6. The application-scoped attribute named "theme"
7. The struts.ui.theme property in struts.properties (defaults to xhtml)
