RichFaces rich:isUserInRole function

I blogged earlier about four built-in RichFaces functions that come in very handy, especially the rich:component(id) one. Many rich components (from rich;* tag library) provide client-side JavaScript API. To access this API, you need to use rich:component(id) and add the JavaScript method name, such as: #{rich:component(‘id’)}.someMethod(). For example, go to rich:listShuttle component in RichFaces Developers Guide and scroll to ReferenceData/JavaScript API section. That’s the JavaScript API you can call on this component.

There is one more, less known function available in RichFaces. It’s called rich:isUserInRole(role). It lets you define security roles in web.xml file and then use the role on a page. For example, suppose only the administrator should see some part of a page:


  Very sensitive information



   General information

In the above example, unless you were authenticated as ‘amdin’, you will not see the top panel. Of course you need the security role in web.xml file. It’s a nice and handy feature to have available.

    Do you Know why I doesn’t work?

    Is this possible to take the user role dynamically?

    like rendered=”#{rich:isUserInRole(bean.getRole())}” instead of
    rendered=”#{rich:isUserInRole(‘admin’)}”

    This will work:

    #{rich:isUserInRole(bean.role)}

    inside the bean you need to have getRole(). Calling a method might only be possible with JBoss EL extension (or in JSF 2).
