我正在使用 JSF 2.3和richfaces 4.5.17 。我想在战争项目中使用Omnifaces。首先，它给了我 ApplicationFactory 类的类冲突异常。通过谷歌搜索，了解了 CDI bean管理器。
现在，我正在尝试在EAR中添加CDI Bean管理器。但是我不断收到以下异常：
{“ WFLYCTL0062：复合操作失败并被回滚。步骤 失败：“ => {”操作步骤2“ => {” WFLYCTL0080：失败 服务” => {“ jboss.undertow.deployment.default-server.default-host./my-war” => “ java.lang.RuntimeException：java.lang.IllegalStateException：CDI BeanManager实例在此环境中不可用。 引起原因：java.lang.RuntimeException：java.lang.IllegalStateException：CDI BeanManager实例不是 在这种环境下可用。 原因：java.lang.IllegalStateException：CDI BeanManager实例在此环境中不可用。 由以下原因引起：java.lang.NullPointerException“}}}}
以下是我的构建结构：
my-ear.ear
-- my-ejb.jar
-- my-entity.jar
-- my-war.war
我已经将空的 beans.xml 文件放在 my-war / WEB-INF 中。
我还在 my-war / WEB-INF / lib 中添加了以下依赖项：
omnifaces-3.4.1.jar
cdi-api-2.0.jar
jsr311-api-1.1.1.jar
weld-se-shaded-3.1.3.Final.jar
我在网上了解到wildfly具有内部CDI，无需单独安装。我提到了这些链接：
CDI Reference omnifaces-exception-cdi-beanmanager-instance-is-not-available-in-jndi
编辑
我使用Omnifaces jar的根本原因是使用byte []获得了图像视图的弹出功能。我想要的另一个功能是在XHTML中包含JSP页面。这些都由Omnifaces共同提供。我在这里遇到的错误的完整日志是：
