appfuse下webwork无法正常调用spring定义Action原因

我们在appfuse中看到xwork直接可以调用spring配置文件action-servlet.xml中的类，那么他们是通过什么方法实现的呢？为什么同样的配置我们的就不可以，原来一切都是因为一个过滤器。

对于上次所遇到关于userAction无法找到的问题经查证如下：

在默认情况下xwork是无法之际在spring中所声明的action类的，如果需要调用则需要在web.xml中添加一个过滤器，代码如下：

   
        securityFilter
        net.sf.acegisecurity.util.FilterChainProxy
   
  
        securityFilter
        /*
   

但是一定要记得，文件net.sf.acegisecurity.util.FilterChainProxy是在acegi-security-x.x.x.jar包里面的，调用前一定要记得放在应用的WEB-INF/lib/目录下才能正常使用。

当系统启动时会自动加载spring配置文件中所声明的类，在appfuse中这一声明是放在action-servlet.xml中的，因此必须将这个文件同其他的applicationContext.xml一起在web.xml中声明为contextConfigLocation的内容，如下：

   
        contextConfigLocation
        /WEB-INF/applicationContext-datasource.xml,/WEB-INF/applicationContext-hibernate.xml,/WEB-INF/applicationContext-service.xml,/WEB-INF/action-servlet.xml
   

在action-servlet.xml中定义如下（这个文件必须符合spring-beans.dtd的规范）：

   
   
   
       
   
   
   

然后在xwork.xml中可以如下调用(这个文件需要符合xwork-1.0.dtd的标准)：

  
            /
            /listUser.jsp
  

不过配置完成以后新的问题又出现了：

在启动服务的时候出现如下异常，错误的等级为严重，正在解决中……
