Could not find action or result There is no Action mapped for namespace / and ac
我想在页面显示条形码图片，于在网上找了个例子，需要在web.xml里面配置
  <servlet>  
<servlet-name>CreateBarCode</servlet-name>  
<servlet-class>com.ssjq.xx.BarCodeServlet</servlet-class>  
</servlet>  

<servlet-mapping>  
<servlet-name>CreateBarCode</servlet-name>  
<url-pattern>/CreateBarCode</url-pattern>  
</servlet-mapping> 
但是会报错，错误代码如下：
13:02:58,002 WARN Dispatcher:49 - Could not find action or result
There is no Action mapped for namespace / and action name CreateBarCode. - [unknown location]

但是怀疑的web.xml里面的配置文件有问题， 之后我去掉里面的
<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>

  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>
就可以显示图片了，但是这样一来我原来的东西就不能显示了
我的strutus.xml的配置如下：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
  "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
