How can I redirect in JSF 2.0

Question

I want to redirect from a link in a JSF page, how can I do it?

In HTML I can use <a> tag for this. But in JSF I use <h:outputLink> or <h:commandLink> as they can be conditionally rendered. I want redirect link to other page in same application or to an external URL. How can I do it with JSF? How can I use action in <h:commandLink> for this?

Assuming that you'd like to redirect to some.xhtml which is placed in web root folder:

1. You can just continue using plain HTML.

   <a href="#{request.contextPath}/some.xhtml">go to some page</a>
   

   For conditional rendering, just wrap it in an <ui:fragment>.

2. Or use <h:link> with implicit navigation.

   <h:link outcome="/some" value="go to some page" />
   

   Note: no need to prepend context path nor to include FacesServlet mapping.

3. Or use <h:commandLink> with ?faces-redirect=true.

   <h:commandLink action="/some?faces-redirect=true" value="go to some page" />
   

   Note: no need to prepend context path nor to include FacesServlet mapping.

4. Or use <h:outputLink>, but you need to specify context path.

   <h:outputLink value="#{request.contextPath}/some.xhtml" value="go to some page" />

Redirecting to an external URL is already answered in this duplicate: Redirect to external URL in JSF.
