I added <Listener className="org.apache.webbeans.web.tomcat.ContextLifecycleListener" /> into server.xml files. After that Tomcat throwed several ClassNotFoundExceptions because it couldn't find OWB libs. I put openwebbeans-impl-1.2.0.jar, openwebbeans-spi-1.2.0.jar, openwebbeans-tomcat7-1.2.0.jar and openwebbeans-web-1.2.0.jar into lib folder. Now Tomcat fails to start with exception ==== Caused by: java.lang.RuntimeException: java.lang.ClassCastException: Cannot cast org.apache.webbeans.service.DefaultLoaderService to org.apache.webbeans.spi.LoaderService at org.apache.webbeans.web.tomcat.ContextLifecycleListener.containerEvent(ContextLifecycleListener.java:200) at org.apache.catalina.core.ContainerBase.fireContainerEvent(ContainerBase.java:1398) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4944) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5434) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) ... 10 more Caused by: java.lang.ClassCastException: Cannot cast org.apache.webbeans.service.DefaultLoaderService to org.apache.webbeans.spi.LoaderService at java.lang.Class.cast(Class.java:3094) at org.apache.webbeans.config.WebBeansContext.<init>(WebBeansContext.java:121) at org.apache.webbeans.config.WebBeansContext.<init>(WebBeansContext.java:98) at org.apache.webbeans.corespi.DefaultSingletonService.get(DefaultSingletonService.java:54) at org.apache.webbeans.corespi.DefaultSingletonService.get(DefaultSingletonService.java:28) at org.apache.webbeans.config.WebBeansFinder.getSingletonInstance(WebBeansFinder.java:51) at org.apache.webbeans.config.WebBeansContext.getInstance(WebBeansContext.java:164) at org.apache.webbeans.config.WebBeansContext.currentInstance(WebBeansContext.java:182) at org.apache.webbeans.web.tomcat.TomcatUtil.inject(TomcatUtil.java:38) at org.apache.webbeans.web.tomcat.ContextLifecycleListener.containerEvent(ContextLifecycleListener.java:182) ... 14 more ==== What I'm doing wrong?
