我尝试通过以下方式将现有应用程序更新到MyFaces 2.2.7（从2.1.7开始）
只需在Maven中更改版本。当我尝试部署该应用程序时，
StackOverflowError（如下）。
我的应用程序通过myfaces-core / impl v 2.1.7成功运行。

如何将myfaces 2.1.7更新到2.2.7？提前致谢..
最佳答案
servletcontainer（Tomcat）本身已经提供了以下库：
el-api-2.2.jar
el-impl-2.2.jar
javax.el-api-2.2.4.jar
jsp-api-2.1.jar
servlet-api-2.5.jar
您不应该在网络应用程序中提供它们。最终只会污染运行时类路径，并导致来自servlet容器和web应用程序的多个不同版本的类之间发生冲突。
相应地修复您的构建，以使这些库不会出现在WAR中。
