本文介绍了如何在JSF 1.2应用中集成Trinidad和Facelets，并解决了配置冲突导致的显示问题。通过调整faces-config.xml和web.xml文件，实现了两者的无缝协作。

Trinidad发布了1.2.1版本，针对JSF1.2实现的组件，下载了Example，将jsf-impl.jar和jsf-api.jar（是SUN对JSF1.2的实现)及其依赖包复制到WEB-INF/lib目录下即可运行了.

参照这个Example就可以创建自己的JSF应用了.

下面主要介绍一下trinidad 与facelets一起使用时我遇到的问题及解决方法：

主要是配置web.xml和faces-config.xml 可以参照https://facelets.dev.java.net/nonav/docs/dev/docbook.html#gettingstarted-setup-web这个文档来配置facelets，后面附有完整的配置好的代码。

需要注意的问题就是：

配置好的facelets后在faces-config.xml中有这样一段代码：

<application>
    <view-handler>
      com.sun.facelets.FaceletViewHandler
    </view-handler>    
</application>

在加入trinidad后这部分变为

  <application>
  <default-render-kit-id>org.apache.myfaces.trinidad.core</default-render-kit-id>

  <locale-config>
   <default-locale>cn</default-locale>
   <supported-locale>en</supported-locale>
  </locale-config>
 </application>

一定要将

    <view-handler>
      com.sun.facelets.FaceletViewHandler
    </view-handler>    
这段删除才可以显示出页面。要不然会提示一个错误：
