本文介绍了一个关于JSF应用中出现的NoSuchMethodError异常问题及其解决方案。该错误主要源于不兼容的JSF实现版本冲突，通过移除web-inflib目录下的jsf-api.jar和jsf-impl.jar文件即可解决问题。

exception 

javax.servlet.ServletException: Servlet execution threw an exception


root cause 

java.lang.NoSuchMethodError: javax.faces.application.Application.getELResolver()Ljavax/el/ELResolver;
	org.apache.myfaces.el.VariableResolverToApplicationELResolverAdapter.resolveVariable(VariableResolverToApplicationELResolverAdapter.java:45)

删除web-inf\lib\jsf-api.jar和jsf-impl.jar就好啦。
