当我尝试加载我的网页时，我遇到以下异常： java.lang.NoSuchMethodError：org.primefaces.context.DefaultRequestContext。（Ljavax / faces / context / FacesContext;）V
我试图找出它来自哪里，但我找不到任何东西:( 您是否曾遇到此异常并知道如何解决它？
以下是Glassfish的完整堆栈跟踪：

正如RongNK所说的那样，我们在类路径中有多个版本的PrimeFaces会导致此错误。再次感谢RongNK：）

我收到了来自@ManagedBean的类似错误
java.lang.NoSuchMethodError：package.ManagedBean。
但是ManagedBean提供了一个方法public init（）{...}
所以这对我有用： 只需为没有错误类参数的公共构造函数实现。
