这是异常

Struts has detected an unhandled exception:

Messages:	
could not initialize proxy - no Session
Error reading 'nameCn' on type entity.Position_$$_javassist_5
An exception occurred processing JSP page /WEB-INF/page/index.jsp at line 33 30: 31:
32:${employee.position.nameCn}
Stacktrace:
File:	org/hibernate/proxy/AbstractLazyInitializer.java
Line number:	132

下面是代码

	public String toIndex(){
		employee = (Employee)ActionContext.getContext().getSession().get("employee");
		return "toIndex";
	}
	public String login(){
		employee = ls.queryLogin(employee);
		if(employee!=null){
			ActionContext.getContext().getSession().put("employee", employee); 
			return "reIndex";
		}
		return "toLogin";
	}

然后是配置

  <filter>
  	<filter-name>OpenSessionInViewFilter</filter-name>
  	<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
  </filter>
  <filter-mapping>
  	<filter-name>OpenSessionInViewFilter</filter-name>
  	<url-pattern>*.action</url-pattern>
  </filter-mapping>

求大佬帮忙

${employee.position.nameCn} nameCn 写错了吧

这是JAVA BEAN

public class Employee 
	private String sn;
	private Position position;
	private Department department;
	private String name;
	private String password;
	private String status;

public class Position
	private Integer id;
	private String nameCn;
	private String nameEn;
	private Set employees = new HashSet(0);

你这一对多的隐射关系，从数据取出来的时候，Position是不是没取出来 你在后台打印下。

我这个是重定向跳转，改成转发的时候是可以出来的 但是SESSION跟重定向没关系啊，所以搞不清什么意思

关于懒加载的问题，在employee = ls.queryLogin(employee);下面加上一句Hibernate.initialize(employee.getPostion());即可。。。
