JSTL functions is not found in JSF

Question

I am trying to add an active class on the page the user is currently viewing but I can't manage to use the JSTL functions. What am I doing wrong? ``` xmlns:fn="http://java.sun.com/jstl/functions" ``` Using this in a `h:link` ``` styleClass="#{fn:containsIgnoreCase(request.requestURI,'index') ? 'active' : ''}" ``` causes this error: ``` styleClass="#{fn:containsIgnoreCase(request.requestURI,'index')}" Function 'fn:containsIgnoreCase' not found ```

Accepted Answer

You've got wrong import, it should be :

```
xmlns:fn="http://java.sun.com/jsp/jstl/functions"
```

You forgot about /jsp
