我试图让BootsFaces，OmniFaces和PrimeFaces与Tomcat 9一起运行：

我也尝试使用旧版本的OmniFaces，但没有成功。
答案 0 :(得分：4)
您的pom.xml不完整。如果您使用与上面列出的完全相同的pom.xml，那么您最终得到的是一个简单的jar文件而不是war文件，并且Maven没有将任何库添加到WEB-INF/lib文件夹中。
要解决此问题，请使用以下步骤：
<packaging>。顺便说一句，您不需要CombinedResourceHandler。它只是一个很好的工具，可以加速你的应用程序，直到http / 2到来。
为方便起见，这是完整的工作pom.xml：
