Question

我想＆＃34;测试负载＆＃34;我的webapp启动时的一些复合控件（xhtml）。但是，当我尝试获取Application上下文（getApplication（））时，我遇到了这个问题：

IllegalStateException: Could not find backup for factory javax.faces.application.ApplicationFactory

顺便说一句，当我删除对getApplication（）的调用时，webapp工作正常。所以我不认为与混合面库相关的其他stackoverflow线程是我的问题。

问题/帮助：

我想我过早地调用getApplication（）了吗？！
我应该在一次性初始化期间何时可以调用它？

说明：

我正在使用Eclipse（Mars）/ Tomcat（8）/ Mojarra（2.2.0）。我的代码目前是一个带有Java bean的简单JSF页面，它最终在静态初始化块中加载缓存配置。因此，当我开始在Eclipse中调试我的一个JSF页面时，Tomcat启动，我的静态初始化程序启动并加载我所有的＆＃34;插入＆＃34;信息。当它试图调用＆＃34; context.getApplication（）＆＃34;我得到＆＃34; IllegalStateException无法找到工厂javax.faces.application.ApplicationFactory＆＃34;的备份。异常。

我的bean类有一个静态初始值设定项，它引用我的ENUM工厂静态值。这是我的ENUM工厂的值（我在ENUM中使用了一些静态初始化技巧，但我认为问题仍然是我早期调用了getApplication（））：

public enum CvcConfigEntities {
    THING1(EntityType.TYPE1),
    THING2(EntityType.TYPE2);

    private static final class StaticBlock {
        private static final String extPropertiesClassPathFmt = CvcConfig.EXT_PROPERTIES_CLASS_PATH_FMT.getValue();
        private static final Logger logger = LoggerFactory.getLogger(CvcConfigEntities.class);
        private static final Properties properties = CvcConfigReader.getProperties();
        private static final Hashtable<EntityType, Hashtable<String, ExtensionDescriptor>> entityTypeExtensionDescriptorsByCode = new Hashtable<>();
        private static final Hashtable<EntityType, List<ExtensionDescriptor>> entityTypeExtensionDescriptorsList = new Hashtable<>();
        static {
            readConfiguredDescriptors();
        }

最后汇集到试图加载复合组件的代码：

public static UIComponent loadCompositeComponent(String taglibURI, String tagName, String id) {
    FacesContext context = FacesContext.getCurrentInstance();

    Application app = context.getApplication(); // <--- here

    ViewHandler viewHandler = app.getViewHandler();
    String rootViewId = context.getViewRoot().getViewId();
    ViewDeclarationLanguage viewDeclarationLanguage = viewHandler.getViewDeclarationLanguage(context, rootViewId);
    UIComponent composite = viewDeclarationLanguage.createComponent(context, taglibURI, tagName, null);

过早调用context.getApplication（）？
