看下是配置的问题
可能是jar包冲突了，看看是不是有重复的jar。
下面这句话可以看看：
The involvement of com.sun.faces in the stack trace however indicates that Mojarra is actually been used. If you're absolutely positive that your webapp bundles MyFaces, then that can only mean that Mojarra is installed elsewhere in the webapp's runtime classpath which has equal or higher classloading precedence over the webapp-supplied libraries, such as locations identified by shared.loader property of Tomcat's /conf/catalina.properties.
一般是charset的问题，改一下应该可以
