LoginAction 文件里面什么都还没做就了几句就这样了具体讲是Session s = HibernateUtil.currentSession();执行后就出问题

package ems_sh.struts.action;

import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForward;
import ems_sh.struts.form.LoginActionForm;
import org.apache.struts.action.Action;

import javax.servlet.http.HttpSession;
import ems_sh.hibernate.HibernateUtil;
import net.sf.hibernate.Session;

public class LoginAction
extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
HttpSession session = request.getSession();
Session s = HibernateUtil.currentSession();
LoginActionForm loginActionForm = (LoginActionForm) form;

/*
String utype =loginActionForm.getUtype();
String uname =loginActionForm.getUname();

String pwd =loginActionForm.getPwd();
String[] userlist = new String[2];
*/

return mapping.findForward( "home ");
}
}
等待高手指点

[解决办法]

<mapping resource= "ems_sh/hibernate/mapping_files/User.hbm.xml "/>
这样写是没问题的~

检查你的hibernate.cfg.xml加载路劲对不对；

你是用myeclipse生成的hbm的么？
删掉之前生成的，全部重新生成一次~

[解决办法]

<classpath>
<classpathentry kind= "src " path= "src "/>
<classpathentry kind= "con " path= "org.eclipse.jdt.launching.JRE_CONTAINER "/>
<classpathentry kind= "con " path= "org.eclipse.jdt.USER_LIBRARY/lib_pms "/>
<classpathentry kind= "output " path= "web/WEB-INF/classes "/>
</classpath>

这是我的配置~

[解决办法]
学习中
[解决办法]
<mapping resource= "classpath:ems_sh/hibernate/mapping_files/User.hbm.xml "/>
改为
<mapping resource= "User.hbm.xml "/>
然后
User.hbm.xml跟hibernate.cfg.xml放同一地方
试一下吧

再有错的话，你就往电脑里面灌水，看他还错不错
[解决办法]

HibernateUtil.java的第13行就是这个吧？
sessionFactory = new Configuration().configure()
.buildSessionFactory();
报的建立sessionfactory出错，就是因为你的hibernate.cfg.xml--> User.hbm.xml--> User.java
这3个关联关系在哪一层出错了~因为不能加载User.hbm.xml；
其实，最先检查调用hibernate.cfg.xml的文件，我不知道你是怎么配置的，因为我是用spring代理的，所以在applicationContext.xml中

<bean id= "sessionFactory " class= "org.springframework.orm.hibernate3.LocalSessionFactoryBean ">
<property name= "configLocation ">
<value> /WEB-INF/hibernate.cfg.xml </value>
</property>
</bean>
先仔细检查hibernate.cfg.xml，User.hbm.xml，User.java单个文件，然后再对应其关联关系；
