Controller Bean没有拿起用户名

Question

我真的遇到了严重的问题。突然间，我正常工作的代码停止了工作。我不知道为什么这么做!!!!最糟糕的是，我今天必须部署我的项目:(。不知道是否说得对，但所有这一切都是在构建路径中添加PrimeFaces后2天开始的。有人可以指引我到正确的方向会很有帮助！

我有以下配置：

1. Glassfish v3
2. Mojara 2.1.6-FCS
3. JPA Eclipselink

控制器Bean

public List<Usergroupdetail> getUsergroupdetail_list() {
        List<Usergroupdetail> myUserGroupDetail = new ArrayList<Usergroupdetail>(
                lODBN.listUserGroupDetail(loginBean.getUsername()));
        System.out.println("username found is:" + loginBean.getUsername());
        return myUserGroupDetail;
    }

从JPA PoJO UserGroupReport获取完整的数据列表

public List<Usergroupreport> getGroupId_list() {
    List<Usergroupreport> myAllgroupIds = new ArrayList<Usergroupreport>(
            lODBN.findAllGroupIdByUser(loginBean.getUsername()));
    return myAllgroupIds;
}

堆栈跟踪

用于登录身份验证的EJB代码段

public boolean validateUser(String username, String password) {
        try {
            Query myQuery = entityManager.createNamedQuery("userverification")
                    .setParameter("username", username)
                    .setParameter("password", password);
            User result = (User) myQuery.getSingleResult();

            if (result != null) {
                System.out.println("Loggin sucessful!");
                return true;

            } else {
                System.out.println("User does not exists in the system");
                return false;
            }
        } catch (NoResultException e) {

            return false;
        }

    }

我尝试将用户名用于我的其他会话bean，直到两天后它才能正常工作。这是我尝试调用从登录bean中选择的用户名的bean的代码
