Hibernate4遇到的一个问题

以下代码中company可以从数据库中正常查找到
但是当保存group时，会报以下问题，

好像是从group表查找最大ID时报错，找不到结果

具体代码：
ApplicationContext ac = new FileSystemXmlApplicationContext("src/resources/applicationContext.xml");

SessionFactory sf = (SessionFactory) ac.getBean("sessionFactory");
Session s = sf.openSession();
Transaction tx = s.beginTransaction();


Company company = (Company) s.get(Company.class, 1L);
System.out.println(company.getComanyAddress()+company.getCompanyName());

Group group = new Group();

group.setNo("8100001");
group.setGroupName("TestZu");
group.setColor("red");
group.setCount(3);
group.setRegistTime(new Date());
group.setCompany(company);

s.save(group);
        tx.commit();
s.close();

根据这个报错是SQL语法错误，group是SQL的关键字，不能作为实体名(表名)。当然实体名可以不改表名可以改。
