这些是提示

这些是 *.hbm.xml

这些是*cfg.xml
-- Table: user

这些是SQL语句
package com.iustice;

public class User implements Serializable {

this.password = password;

this.username = username;
}
public String getUsername() {
return username;
}
public long getId(){
return id;
}
public void setId(int id){
this.id=id;
}
}
这些是实体类
package com.iustice.user;

Session s=HibernateUtil.currentionSession();
Query q=s.createQuery( "from User u where u.username= ' "+username+ " ' and password= ' "+password+ " ' ");

return(mapping.findForward( "loginfail "));
}
else{
HibernateUtil.closeSession();
request.getSession().setAttribute(username,username);
return mapping.findForward( "loginsuccess ");
}
}
}
这些是代码
请大家给看一看吧
我实在是弄捕处来了~~~~
[解决办法]
*.hbm.xml中class name要写完整的包名
既然是mappingexpection那么你应该要想到是映射文件没配制好
[解决办法]
你自己试验一下 用eclipse工具装上middlegen插件 在数据库里建立一张表，使用middlegen自动创建所有的东西（配置文件和javabean），估计不会有错了，按照这个过程来试一次吧
[解决办法]
帮你顶,不过觉得可能是你程序写的有问题,貌似不是配置文件的问题.
[解决办法]
应该是你的配置文件的问题，因为已经提示你XML读的时候有错误了
[解决办法]
<id name= "id " column= "Id " type= "int " >
<generator class= "increment "> </generator>
</id>
以上错
---------------------------------------------
Caused by: org.xml.sax.SAXParseException: The content of element type "id " must match "(meta*,column*,type?,generator?) ".
----------------------------------------------
<id name= "id " type= "int ">
<column name= "id "/>
<generator class= "increment "/>
</id>
