我正在尝试在Eclipse上设置Web应用程序.我使用的是Tomcat 6.0和jdk 1.6.0_23.出于某种原因,我收到此错误:

我遇到了HibernateTemplate的问题,我不知道我哪里出错了.我正在使用Hibernate3和Tomcat6.在我的DAO中,我有一些函数试图使用字符串查询数据库,它们似乎工作正常.像这样

public AppUser getUserByUserName(String username){
    HibernateTemplate template=new HibernateTemplate(sessionFactory);
    try{
        List<AppUser> appList = template.find(" from AppUser as au where au.username=?", username);
        tempUser = appList.get(0);  
        return tempUser;
    } catch(Exception e){
        System.out.println("Problem in AppUserDao--get byUsername: " + e.toString());
        return null;
    }
}

然而,当我尝试使用整数查询时.喜欢:

public List<AppUser> getAllMerchants(){
    HibernateTemplate template=new HibernateTemplate(sessionFactory);
    try{
        List<AppUser> appList = template.find(" from appuser as au where au.securityLevel!=?", 112);
        if(appList.size() > 0)
            return appList;
        else
            return null;
    } catch(Exception e){
        System.out.println("Problem in AppUserDao--getAllMerchants: " + e.toString());
        return null;
    }
}
