Seam导航文件pages.xml的读取

   我们都知道seam的导航文件pages是放在了WEB-INF下面，而且名字固定为pages.xml

   其实我们可以改变它的名字跟 存放路径：

 

 

 只需要在components.xml文件中定义：

 

<component name="org.jboss.seam.navigation.pages"
  class="org.jboss.seam.navigation.Pages">
  <property name="resources">
   <value>/WEB-INF/pages.xml</value>
   <value>/META-INF/jira_pages.xml</value>   
  </property>
 </component>

 

 

就可以定义你自己的导航文件了jira-pages.xml
