This is just a quick reminder for myself how to implement programmatic redirects with JBoss Seam and JSF.
I will describe three different techniques:
- Redirecting to a 404 Error Page from a JSF Backing Bean
- Redirecting to an external Website
- Redirecting to a JSF view in a Seam Application
Redirecting to a 404 Error Page from a JSF Backing Bean
1 2 | final HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse(); response.sendError(HttpServletResponse.SC_NOT_FOUND); |
Redirecting to an external Website
1 2 | ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext(); ((HttpServletRequest) ec.redirect("http://example.com/"); |
Redirecting to a JSF view in a Seam Application
Thanks to Jeremiah Orr from Stackoverflow for this tip! (see: Stackoverflow Thread)
1 2 3 4 5 6 7 8 9 10 11 12 13 | @Name("yourBean") public class YourBean { @In Redirect redirect; public void yourMethod() { redirect.setViewId("/someView.xhtml"); redirect.setParameter("someParam", "someValue"); redirect.execute(); } } |
OR
1 | FacesManager.instance().redirect("/someView.xhtml", paramMap, conversationPropagationEnabled, includePageParams); |
