oracle - JSF Faces Bridge 在部署到 oc4j 容器时得到 java.lang.NullPointerException

Question

我正在使用 Webcenter 预配置的 oc4j 运行 JDeveloper 10.1.3.4。
我正在尝试 portletize 一个 vanilla JSF webcenter 项目。

我使用 webcenter 应用程序模板创建了一个应用程序。

添加一个 JSF JSP，简单地将其称为具有所有默认值的索引。

添加部署配置文件并部署到本地 oc4j

导航到 jsf 页面，一切正常。

右键单击 ViewController 并添加库 Portlet Faces Bridge

右键单击 ViewController 并添加 Portlet 部署描述符。

使用来自 link text 的值编辑 portlet.xml

在 portlet.xml 中，我用我的/index.jspx 替换了默认页面 View

当我尝试部署到本地 oc4j 时，我得到以下信息

如果我手动部署 WAR 文件并导航到该页面，则会出现 500 内部服务器错误。

我的 portlet.xml 文件看起来像

...如果我删除文件并重新部署 jspx 页面工作正常。

您应该转向使用比 oc4j 好得多的 wls 的 jdev 11g
