我正在尝试为我的Java EE/JSF2应用程序实现正确的注销.

它需要两件事:

1. 我需要从JAAS注销并使会话无效
2. 然后,我必须导航到外部URL以触发Siteminder注销

Siteminder注销URL(在策略服务器上配置 - >我无法更改它)在我的应用程序上下文之外.例如.如果我的webapp URL是https:// localhost:8080/sm/MyWebApp,那么注销URL是https:// localhost:8080/anotherwebapp/logout.html.

这是当前的本地注销代码:

public void logout() {
    System.out.println("Logging out...");
    HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
    try {
        request.logout();
    } catch (ServletException e) {
        e.printStackTrace();
    }
    HttpSession session = (HttpSession)FacesContext.getCurrentInstance().getExternalContext().getSession(false);
    if (session != null) {
        session.invalidate();
    }
}

以下是生成注销URL的属性:

public String getLogoutUrl() {
    HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
    String requestServer = request.getServerName();
    String requestScheme = request.getScheme();
    int serverPort = request.getServerPort();
    String logoutUrl = requestScheme + "://" + requestServer + ":" + …

我尝试使用prime faces库设置JSF项目当我运行此设置时,它显示跟随错误

org.apache.jasper.JasperException: javax.servlet.ServletException: null source
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:54
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:417)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:320)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)

我无法找到背后的原因.
以下是设置

Folloing是我在web-inf/lib中包含的库
1. jsf-api-2.0.3.jar
2. jsf-impl-2.0.3.jar
3. jstl-1.0.2.jar
4. primefaces-3.4.jar
