Goal: I wan to decelerate logout button in template.
Scenario: I am building j2ee 6 application with jsf 2.0 for web part.

SecurityBacking.java :
@Named("securityBacking")
@RequestScoped
public class SecurityBacking {
public String logout() {
String result = "/login?faces-redirect=true";
FacesContext context = FacesContext.getCurrentInstance();
HttpServletRequest request = (HttpServletRequest) context.
getExternalContext().getRequest();
try {
System.out.println("calling logout");
request.logout();
System.out.println("called logout");
} catch (ServletException ex) {
Logger.getLogger(SecurityBacking.class.getName()).
log(Level.SEVERE, null, ex);
result = "/loginError?faces-redirect=true";
}
return result;
}
public boolean isInRole(String role) {
ExternalContext external = FacesContext.getCurrentInstance().getExternalContext();
HttpServletRequest request = (HttpServletRequest) external.getRequest();
String user = request.getRemoteUser();
return request.isUserInRole("partner");
}
public void invalidate() {
try {
HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
request.getSession(false).invalidate();
response.sendRedirect(request.getContextPath());
} catch (IOException e) {
e.printStackTrace();
}
}
}
As you see :
<h:commandButton value="log out" action="#{securityBacking.logout}" />
and
<h:commandButton value="Do log out" action="#{securityBacking.invalidate}" />
are decelerated in layout/template.xhtml & index.xhtml, but buttons decelerated in layout/template.xhtml not working in the sam time, they working in index.xhtml.
When i looking to Safari web inspector i see :
for decelerated in index.xhtml
<input xmlns="http://www.w3.org/1999/xhtml" type="submit" name="j_idt12:j_idt29" value="log out" />
and for layout/template.xhtml
<input xmlns="http://www.w3.org/1999/xhtml" type="submit" name="j_idt32" value="log out" />
As I understand bean not injecting daclets template inside tag, but I haven`t find anything about this in j2ee 6 tutorials & spec, or maybe рфмут'е notice such information.
Q1: Am I right about injection?
Q2: Why It is not injecting through templating ?
Q3: What is the different way to templating in this case?
Q4: What is the best practice for this case?
(I am using glassfish v3 web server)
Thank you !
