Redirecto to another page with a filled form in JSF? - facebook

Question

I'm trying to do a 'login with facebook' button, which works ok, but I would like to redirect to another page with the user data filled in a form.
SocialFacebook Controller
public void login(){
try {
//Create an instance of SocialAuthConfig object
SocialAuthConfig config = SocialAuthConfig.getDefault();
//load configuration. By default load the configuration from oauth_consumer.properties.
//You can also pass input stream, properties object or properties file name.
config.load();
//Create an instance of SocialAuthManager and set config
SocialAuthManager manager = new SocialAuthManager();
manager.setSocialAuthConfig(config);
//URL of YOUR application which will be called after authentication
String successUrl = "http://localhost:8080/cc/pages/system/register.xhtml";
// get Provider URL to which you should redirect for authentication.
// id can have values "facebook", "twitter", "yahoo" etc. or the OpenID URL
String url = manager.getAuthenticationUrl("facebook", successUrl);
// Store in session
HttpSession session = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(false);
session.setAttribute("authManager", manager);
//after check out in facebook, redirect to the proper page
logged();
//redirect to the successful login page
FacesContext.getCurrentInstance().getExternalContext().redirect(url);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
So when the user hit the button, 'log in with facebook' in my index.xhtml:
<h:body>
<h:form id="login-facebook">
<h:commandButton id="login" action="#{socialFacebook.login}" value="Login"/>
</h:form>
</h:body>
It redirects to register.xhtml page with the URL like this:
http://localhost:8080/cc/pages/system/register.xhtml?code=AQC_3oCPjlyvZ51dpzxVdBNS1JfgwwZluBSduU7FG01esgVQT6Qxq8gWYRUsGz64aXDvXB1195m0CHZGmdvsmjLxtmbuUSSSqH7i49pcb6g9Begt4Yol1rqWFQGGGGGGGGGGGJ9mlWiEq4Aknlh1J2su2a9l0GzyLB21J4BgNgfBw3DUtwn-RkT00E7BsFpISiXKE7EVsT5NgxPBtOWIUY#_=_
The thing is now, I would like to get this code in my bean and do the checking and fill the form in register.xhtml
So I create this method at the same bean :
private void logged(){
FacesContext facesContext = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(false);
SocialAuthManager manager = (SocialAuthManager) session.getAttribute("authManager");
try {
// get the auth provider manager from session
if (manager != null){
// call connect method of manager which returns the provider object.
// Pass request parameter map while calling connect method.
HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);
AuthProvider provider = manager.connect(paramsMap);
// get profile
Profile p = provider.getUserProfile();
session.setAttribute("profile", p);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
But it I'm not able to get the parameter code from my request.
How can I get this code, do the checking and fill the form after that ?

I solve my problem creating a webfilter which gets the request and responde then I could fill the user date in my url and get then in my form page:
#WebFilter("/facebook/*")
public class LoginFilter implements Filter {
#EJB UserEAO userEAO;
#Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws ServletException, IOException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
HttpSession session = request.getSession();
FacesContext facesContext = FacesContext.getCurrentInstance();
try {
SocialAuthManager manager = (SocialAuthManager) session.getAttribute("authManager");
Map<String, String> paramsMap = SocialAuthUtil.getRequestParametersMap(request);
AuthProvider provider = manager.connect(paramsMap);
// get profile
Profile p = provider.getUserProfile();
if (userEAO.find(p.getEmail()) == null){
response.sendRedirect
(
request.getContextPath() +
"/pages/system/register.xhtml?" +
"firstName=" + p.getFirstName()
);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
This is my register page:
<ui:composition template="/resources/jsf/include/default.xhtml">
<ui:define name="title">
</ui:define>
<ui:define name="header">
</ui:define>
<ui:define name="content">
<h:form id="register_form">
<f:metadata>
<f:viewParam name="firstName" value="#{userc.userb.user.firstName}" />
</f:metadata>
Name: <h:message id="m_name" for="name" styleClass="red" />
<h:inputText id="name" value="#{userc.userb.user.firstName}">
<f:validateLength minimum="1" maximum="20" />
<f:ajax event="blur" render="m_name" />
</h:inputText>
