Spring Security Logout

I ran into trouble with Spring Security. I´m able to login but not to logout (at least not as expected).

After login, I will be redirected to /secure/home.xhtml <- this works fine and as expected. But I´m not able to logout through #{request.contextPath}/logout. (I have changed the logout url in the spring security config, but I also tried it with the default one) There is always a 404.

Here the code so far:

index.xhtm <- works fine

<form method="POST" id="loginForm" action="#{request.contextPath}/j_spring_security_check" class="form-signin" autocomplete="off">
            <div class="form-group">
                <label for="username" class="control-label">#{bundle["login.username"]}</label>
                <input type="text" name="username" id="username" class="input-block-level form-control"
                       placeholder="#{bundle['label.username']}" required="true" tabindex="1" />
                <span class="help-block"></span>
            </div>
            <div class="form-group">
                <label for="password" class="control-label">#{bundle["login.password"]}</label>
                <input type="password" class="input-block-level form-control" name="password" id="password" tabindex="2"
                       placeholder="#{bundle['label.password']}" required="true" />
                <span class="help-block"></span>
            </div>
            <button type="submit" tabindex="3" class="btn btn-success btn-block">#{bundle["login.action"]}</button>
            <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" />
        </form>

spring-security.xhtml, http conf

<security:http use-expressions="true" >
        <security:intercept-url pattern="/secure/**" access="hasAnyRole('USER','ADMIN')" />
        <security:intercept-url pattern="/admin/**" access="hasRole('ADMIN')" />
        <!--<security:access-denied-handler error-page="/404.xhtml" />-->
        <security:form-login 
            login-page="/index.xhtml" 
            default-target-url="/secure/home.xhtml" 
            authentication-failure-url="/index.xhtml?error"
            username-parameter="username" 
            password-parameter="password" />
        <security:logout logout-url="/logout" logout-success-url="/index.xhtml?logout" invalidate-session="true" delete-cookies="JSESSIONID" />
        <security:csrf />
    </security:http>

This is the way I tried to implement the logout regarding to other answers here on stackoverflow:

<a href="#{request.contextPath}/logout">logout</a>
                    <h:outputLink value="#{request.contextPath}/logout">Logout</h:outputLink>

But both links doesn´t work. I get the 404. I also read that you should replace request.contextPath with pageContext.request.contextPath but that did not work too. (instead of localhost:8080/myContext/logout the link will redirect me to localhost:8080/logout)

A tutorial showed me, that logging out can be also implemented with this:

<form method="POST" id="loginForm" action="#{request.contextPath}/logout" class="form-signin" autocomplete="off">
                        <button type="submit" tabindex="3" class="btn btn-success btn-block">#{bundle["logout.action"]}</button>
                        <input type="hidden" name="#{_csrf.parameterName}" value="#{_csrf.token}" />
                    </form>

At beginning it seemed to solve my problem, but after adding more pages to the secure section, for example "profile.xhtml", I came accross the undesireable behaviour that I get logged out after the page is loaded. So if I add the logout-form as above in my home.xhtml, it seems that I get logged out even if I do not click on logout. If I refresh the page, I will be redirected to index.xhtml (login) even if I did NOT click on Logout. So If I click on the link to profile.xhtml I will naturally be redirected to index.xhtml as spring thinks I logged out. Without this form, I stay logged in, but not able to logout! It´s a mess!

Ah and if I click on the logout button on the form, I get the following error:

HTTP Status 403 - Expected CSRF token not found. Has your session expired?

type Status report

messageExpected CSRF token not found. Has your session expired?

descriptionAccess to the specified resource has been forbidden.

I have really no idea whats wrong with my config :(!

Using GlassFish 4.1, spring framework version 4.1.2.RELEASE, and spring security version 3.2.5.RELEASE.

I would appreciate every answer. This error already took two days without any solutions :(
