I was trying to create a secure login page with jsf, and I used these code snippets as the solution, found in this question. My problem is, that I can access the /restricted/secret.xhtml without logging in, there is no redirect it's like the filter is not applied, because if I go directly to the /restricted/secret.xhtml the #{user.loggedIn} evaluates to false and I still can view the page. Here is my code:
AuthFilter.java
public class AuthFilter implements Filter {
private FilterConfig config;
@Override
public void destroy() {
this.config = null;
}
@Override
public void doFilter(ServletRequest req, ServletResponse resp,
FilterChain ch) throws IOException, ServletException {
HttpSession s = ((HttpServletRequest) req).getSession();
if (s.getAttribute(UserBean.CREDENTIAL)==null)
{
((HttpServletResponse) resp).sendRedirect("/login.faces");
}else
{
ch.doFilter(req, resp);
}
}
@Override
public void init(FilterConfig config) throws ServletException {
this.config = config;
}
}
UserBean.java
@ManagedBean(name="user")
@SessionScoped
public class UserBean implements Serializable {
private String name;
private String password;
protected static final String CREDENTIAL = "ontherun";
private static final long serialVersionUID = 1L;
public String getName()
{
return this.name;
}
public void setName(String newName)
{
this.name = newName;
}
public String getPassword()
{
return this.password;
}
public void setPassword(String newPassword)
{
this.password = newPassword;
}
public boolean isLoggedIn()
{
return FacesContext.getCurrentInstance().getExternalContext()
.getSessionMap().get(CREDENTIAL) != null;
}
public String logout() {
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove(CREDENTIAL);
return null;
}
public String login()
{
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put(CREDENTIAL, this.name);
return "secret";
}
}
Here is my login.xhtml ; the page works correctly, so there is no problem with the template file.

Here is the secret.xhtml which is supposed to be restricted:

You've mapped FacesServlet on /faces/* instead of *.xhtml. So all JSF requests will have the /faces prefix in the URL. But you've mapped the AuthFilter on /restricted/* instead of /faces/restricted/*, so it will never kick in on /faces/* URLs.
You can solve this in 2 ways:
Map FacesServlet on *.xhtml instead of on /faces/*. This has the additional advantage that the enduser won't ever be able to see the raw JSF source code when the enduser purposefully removes the /faces path from the URL in browser address bar.
Map AuthFilter on /faces/restricted/* instead of on /restricted/*.
I personally recommend the first way. You end up with a shorter and nicer URL and you immediately also prevent the JSF source code leak.
