Selecting Themes

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.xml (defaults to xhtml)

See Can I change theme on a per-page basis page for using scoped theme attribute.

Tips

• To override an entire form’s theme, change the “theme” attribute of the form. (Convenient for using the ajax theme for specific forms, for example.)
• To support user-selected themes, set the theme in the user’s session.
• To change the theme for the entire application, modify the struts.xml.
