求救！！！困扰了一个多星期的s2sh整合问题急求高手解决。

      是关于spring整合hibernate的问题。测试类可以实现功能，但是在Action中访问就出现空指针问题。感觉就是sessionFactory没有注入到里边去。
       下面是控制台报的错误

Error configuring application listener of class org.springframework.web.context.ContextLoaderListener
java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener            有Spring.jar包呢，怎么会有这样的错误。
         测试类中是利用ClassPathXmlApplicationContext读取配置文件没有问题。
         在web中是tomcat自己读取的配置文件，web.xml里面配置的listener也没问题。

太郁闷了！！！！大虾们指点指点。。在线等！！！！！！

别用监听，有时候容易出错，直接写成servlet试试！

看一下是否有没加到项目的buildpath里...
难倒不是这里的问题？关键是我在test类中可以实现的
test类代码 public static void main(String args[]) throws SQLException
{
BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");
Service h=(Service)factory.getBean("categoryService");
List<Category>list= h.getCategory();
      System.out.print(list);
}
action中的代码
public String list() throws SQLException {
this.categories=categoryService.getCategory();
return SUCCESS;
}
lz是用Eclipse吗？
如果是，你到项目的根目录下，有一个.classpath文件，这个文件记录了web项目的classpath。
你打开贴上来看看
你看看struts中的代理用的有没有问题

确认一下spring lib里有没有spring.jar.
如果有，就不是jar没导入的原因了。。
我测试过如果我把public String list() throws SQLException {
this.categories=categoryService.getCategory();
return SUCCESS;
}
这段代码改成 public String list() throws SQLException {

BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");
HibernateDaoImpl h=(HibernateDaoImpl)factory.getBean("CategoryDao");

this.categories= h.getCategory();
return SUCCESS;
}  就没有问题！！！
<listener-class> org.springframework.web.context.ContextLoaderListener </listener-class>
去掉所有的空行，和空格。
些成一行试试。。
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 以前遇到过因为配置是从别的地方copy过来的，因为编码问题导致错误的情形。

之前的

错误应该解决了。
这是新的错误了。
看一下这个吧：
http://blog.sina.com.cn/s/blog_4a9eb8290100al4b.html
不是。之前的java.lang.ClassNotFoundException:org.springframework.web.context.ContextLoaderListener   是tomcat报的错。
后来的那个是我redeploy项目报的错
有包并不代表着有类啊，进包里看看是否真的有你配置的那个Listener类
不是这个的问题。因为tomcat会读取配置文件。如果配置文件错了，tomcat 也会报错。
有人用过CVS么？感觉程序在修改的时候经常出现错误。想回到错误之前很麻烦！！！！
如果测试能通过，action报错的话，是不是你没有加这个包：
struts2-spring-plugin-2.1.8.1.jar
并且struts的xml文件中要申明：

<constant name="struts.objectFactory" value="spring" />
