Java 不支持操作异常JSF-webLogic 11g

我正在开发一个web应用程序，并使用以下版本：

弹簧芯3.1.3 SpringWebMVC 3.1.3 SpringWebFlow 2.3.1 弹簧面2.3.1 JSFAPI 2.0.9 jsf impl 2.0.9 java 1.6 该应用程序部署在WebLogic server 10.3.6中。 下面显示的异常是在我浏览应用程序时随机引发的

@SessionScoped
public class bean implements Serializable{

我不知道你希望这里的人为你做什么。有一个完整的堆栈跟踪，您需要一步一步地查看它以找出哪里出了问题。除了您之外，没有人拥有此堆栈跟踪所指的代码。这是一个奇怪的情况，因为有时工作，有时抛出异常。唯一清楚的一点是，引发此异常是因为defaultFacesContext为null。您的类路径上是否有多个版本的javax.faces.context.FacesContext？这个调用在Java1.6中确实存在，但在1.5中却不存在。我所做的是将jstl从pom中排除，它成功了！！！jstljavax.servlet
