The default name of the JSF config file is WEB-INF/faces-config.xml. And it's "faces-config", not "face-config".
Despite what some people think, annotations don't always mean that you don't need a faces-config.xml file. Not everything that faces-config.xml declares have corresponding annotations. However, it sounds like you may not be properly configured for JSF annotation scanning. Since that's a NetBeans issue, you may need to ask in the IDEs forum.
An IDE is no substitute for an Intelligent Developer.
