问题： myeclipse下开发JAX-RS + Hibernate时报javaxservletServletException: NoClassDefFound
描述:本帖最后由 shisjj11 于 2012-11-15 13:13:00 编辑
在添加了Hibernate3.3 和 JAX-RS1.0后，编写测试代码如下：
@GET
@Path("p)
@Produces("application/json")
@Consumes("text/html")
public String ff() String password) {
Session s = null;
Transaction ts = null;
Users tUsers = new Users();
tUsers.setEmail("1");
tUsers.setPassword("2");
s = HibernateSessionFactory.getSession();
ts = s.beginTransaction();
......
在运行到
s = HibernateSessionFactory.getSession(); 一句（倒数第2句）的时候报错。
错误信息如下：

org.hibernate.Session 这个类是在hibernate.jar中的，难道像JAX-RS之类的REST框架不能加入其他jar包吗？
是不是还需要配置其他的servlet？
