JSF - spring - hibernate and session

Question

Hi,
I'm currently using hibernate spring and JSF
1/ the first problem
In the JSF common header page I try to test if a bean is in the session scope in order to show login or logout link, and the test always fails : the logout link is always displayed.
the JSF page :
<f:subview id="header" >
    <h:form id="headerForm">
        <table cellspacing="0" width="100%">
    <tr>
        <td align="left" valign="middle">
              <a href="front.jsf"><img border="0" src="images/logo1.jpg"/></a>
        </td>
    <td align="right" valign="middle"> <br>
   <!--<a href="front.jsf" rendered="#"> Accueil<</a> -->
    <c:choose>
                <c:when test="${empty sessionScope.accountBean}">
                    <h:commandLink action="Sign on">
                        <h:outputText value="Sign on"/>
                    </h:commandLink>  
                </c:when>
                <c:otherwise>
                    <h:commandLink id ="logout" action="#{accountBean.logoutAction}" >
                         <h:outputText value="log out"/>
                    </h:commandLink>
               </c:otherwise>
            </c:choose>
        </td>
    </tr>
</table>
<table cellspacing="0" width="100%">
    <tr>
        <td>
            <hr color="#99ca3c"  size="5" noShade SIZE=1>
        </td>
    </tr>
</table>
     </h:form>
</f:subview>The accountBean code :
public class AccountBean extends BaseBean{
//private Logger log = Log.getLog(this);
    private String uid;
    private String password;
    private boolean loggedIn;
    private AdminService adminService;
    private Admin admin;
    public AccountBean() {
        this.logger.debug("Authentication");
        this.loggedIn = false;
        uid=null;
        password=null;
       // admin=new Admin();
public String loginAction() {
          try {
                    this.logger.debug("loginAction");
                     admin = adminService.login(this.uid, this.password);
                                //this.serviceLocator.getUserService().login(this.username, this.password);
               if (admin != null) {
                            if("".equals(admin.getUid())|| "".equals(admin.getPassword())){
                             this.loggedIn=false;
                                String msg = "Le mot de passe et l'identifiant doivent etre saisis ";
                    addErrorMessage(msg + ", saississez un mot de passe et un identifiant corrects");
                             return NavigationResults.RETRY;
                            else{
                    this.loggedIn = true;
                                HttpSession session = SessionUtil.getSession();
                                session.setAttribute("Admin", this.uid);
                    return NavigationResults.SUCCESS;
               else {
                    this.loggedIn = false;
                    String msg = "Le mot de passe est incorrect ";
                    addErrorMessage(msg + ", saississez un mot de passe correct");
                    this.logger.debug(msg);
                    return NavigationResults.RETRY;
          catch (UsernameNotExistException ue) {
               String msg = "L'identifiant (login) est incorrect";
               this.logger.info(msg);
               addErrorMessage(msg + ", ressaysissez votre identifiant.");
               return NavigationResults.RETRY;
          catch (Exception e) {
               this.logger.error("Could not log in user.", e);
               addInfoMessage("Could not log in user: Internal Error");
               return NavigationResults.FAILURE;
      * The backing bean action to logout a user.
      * @return the navigation result
     public String logoutAction() {
          //this.clear();
           FacesContext fc = FacesContext.getCurrentInstance();
           HttpSession session = (HttpSession) fc.getExternalContext().getSession(false);
           session.invalidate();
          this.logger.debug("Logout successfully.");
          return NavigationResults.MAIN;
    public String getPassword() {
        return password;
    public void setPassword(String password) {
        this.password = password;
    public String getUid() {
        return uid;
    public void setUid(String uid) {
        this.uid = uid;
    public Admin getAdmin() {
        return admin;
    public boolean getLoggedIn() {
        return loggedIn;
    public void setLoggedIn(boolean loggedIn) {
        this.loggedIn = loggedIn;
    public void setAdminService(AdminService adminService) {
        this.adminService = adminService;
}the faces managed bean configuration
<managed-bean-name>accountBean</managed-bean-name>
    <managed-bean-class>fr.cbmjadmin.views.bean.AccountBean</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
     <property-name>adminService</property-name>
            <value>#{adminService}</value>
    </managed-property>2/ the second problem :
my application shows a list of datas.
I log on the application , i update this list outside the application ( by using sql command) , i try to list my data using the application : the application does not reflect the modifications. I logout using the log out link, then i log on and the application does not reflect the modifications.
what happens?
How could I resove these problems.
How can i logout properly?
how can i show logout link when the user is logged in? and hide the log out link when the user is logout
Thanks.

Answer 1

It depends on how you want to reprecate the session btwn instances or cluters
there are three kinds File System, Memory to Memory, HA
You can configure it from this property in the admin console
Configuration on a cluster -> Availability Service -> Web Container Availability -> Persistence Type:
