        （省略...）然后是有问题的源码：
package actions;import beans.Dao;import com.opensymphony.xwork2.ActionSupport;public class LoginAction extends ActionSupport{
    private String name;
    private String pwd;
    Dao dao=new Dao();
    
    public String execute(){  
     System.out.println(name+"  "+pwd);
     if(dao.validate(name, pwd)){
     System.out.println("success");
     return SUCCESS;
     }
     System.out.println("error");
     return ERROR; 
    }
这是ACTIONS 错误就在这里 后台HIBERNATE还有MYSQL什么的都配置好了  求高手教我

Answer 1

java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I看看你的源码， 是不是多了个I

Answer 2

这是操作类
public class Dao {
public boolean validate(String name,String pwd) {
Session session = HibernateSessionFactory.getSession();
Query q = session.createQuery("from User u where u.user=:name and u.pwd=:pwd");
q.setParameter("name", name);
q.setParameter("pwd", pwd);
List list=q.list();
if(!list.isEmpty()){
return true;
}
return false;
}

Answer 3

解决了 是altlr 2.7.2的jar包版本太低 换了2.7.6的版本就OK了
