我们正在使用基于 Maven 的 EE 应用程序（EAR）。应用服务器为：Galssfish V2.1，IDE为：Netbeans7.0，框架为JSF1.2。所以我们正在尝试从 glassfish v2.1 迁移到 glassfish v3.1。我已经完成了类似在 web.xml 中添加的更改
<context-param>
<param-name>javax.faces.DISABLE_FACELET_JSF_VIEWHANDLER</param-name>
<param-value>false</param-value>
</context-param>
并在 faces-config.xml 中的 application 标记中定义 viewHadler，例如
<view-handler>org.ajax4jsf.application.AjaxViewHandler</view-handler>
完成这些修改后，我遇到了两个问题：
- 部署应用程序时未创建资源。
为此，我手动创建了资源。所以应用程序已部署，但我可以看到唯一的错误页面。在服务器日志中，我发现了异常详细信息，例如：

有人可以提出一些建议来解决这些问题吗？
