Hi folks! There are 2 different ways to work with OpenWebBeans and tomcat.
A, your app is using CDI but you do not need the container to understand CDI. In that case just add owb-core jar + spi + xbean-asm4-shaded + owb-web into your WEB-INF/lib and add WebBeansConfigurationListener to your web.xml as <listener> This works perfect, but be aware that there is no CDI injection in Servlets themself. You can of course use DeltaSpike BeanProvider to pick up B.) you need it fully integrated with all other EE technologies. In that case I suggest you use TomEE. This is basically tomcat7 + latest OWB + latest MyFaces + + +. And all that in a perfectly integrated and ready to use configuration.
