I try to create login form in web application. in JSP page I can use
<%
String name = request.getParameter( "username" );
session.setAttribute( "theName", name );
%>
but now I am using JSF /Facelets for web application I don't know how to create session in JSF Backing bean for client and check if user is logged in or not so it will redirect into login page. who can help me give me link tutorial for these problem ? thank you before
Now I have little problem with mapping into web.xml code snipped of class Filter
@Override
public void init(FilterConfig filterConfig) throws ServletException {
this.config = filterConfig;
}
@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
LoginController controller = (LoginController) req.getSession()
.getAttribute("loginController");
if (controller == null || !controller.isLoggedIn()) {
res.sendRedirect("../admin/login.xhtml");
} else {
chain.doFilter(request, response);
}
}
and in web.xml
I map with <fitler>
tag
<filter>
<filter-name>userLoginFilter</filter-name>
<filter-class>com.mcgraw.controller.UserLoginFilter</filter-class>
<init-param>
<param-name>loginPage</param-name>
<param-value>/login.xhtml</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>userLoginFilter</filter-name>
<url-pattern>/admin/*</url-pattern>
</filter-mapping>
I have one folder admin in web project and I check if the user is not logged in with admin permission to not access page (I can do the permission check) but when I use the filter the browser doesn't understand url ?? no StackTrace show when the browser doesn't understand url
Error shown on Firefox
The page isn't redirecting properly
on IE it loading ... loading . .. non-stop
now I change condition which check if req.getPathInfo.startsWith("/login.xhtml") it will do chain
I have 2 idea but it response 500 HTTP STATUS
if (controller == null || !controller.isLoggedIn()) {
res.sendRedirect("../admin/login.xhtml");
if(req.getPathInfo().startsWith("/login.xhtml")){
chain.doFilter(request, response);
}
} else {
chain.doFilter(request, response);
}
===============
if (controller == null || !controller.isLoggedIn()) {
if (!req.getPathInfo().startsWith("/login.xhtml")) {
res.sendRedirect("../admin/login.xhtml");
} else {
chain.doFilter(request, response);
}
} else {
chain.doFilter(request, response);
}
====================== update Class loginController
package com.mcgraw.controller;
import com.DAO.UserBean;
import com.entity.IUser;
import java.io.Serializable;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
/**

*/
@ManagedBean
@SessionScoped
public class LoginController implements Serializable {
@EJB
private UserBean userBean;
private IUser user;
private boolean admin;
private boolean mod;
private PasswordService md5;
/** Creates a new instance of LoginController */
public LoginController() {
user = new IUser();
md5 = new PasswordService();
}
// getter / setter
public boolean isMod() {
return mod;
}
public void setMod(boolean mod) {
this.mod = mod;
}
public IUser getUser() {
return user;
}
public void setUser(IUser user) {
this.user = user;
}
public boolean isAdmin() {
return admin;
}
public void setAdmin(boolean admin) {
this.admin = admin;
}
public String cplogin() {
String md5Password = md5.md5Password(user.getPassword());
if (userBean.userLogin(user.getUsername(), md5Password) != null) {
if (user.getUsername() != null || md5Password != null) {
user = userBean.userLogin(user.getUsername(), md5Password);
if (user.getGroups().getAdmin() != null) {
setAdmin(user.getGroups().getAdmin());
}
if (user.getGroups().getMods() != null) {
setMod(user.getGroups().getMods());
}
if (isAdmin() == true || isMod() == true) {
return "home";
} else {
return "login";
}
} else {
return "login";
}
} else {
return "login";
}
}
public String logout() {
user = null;
return "login";
}
public boolean isLoggedIn() {
return user != null;
}
}
I have new problem if render JSF taglib with method loggedIn, in index page (not in admin folder) user doesn't login can see what I render example, <== this like if user doesn't login user can't see but why can he see it?
