question：
When I build this test application and deploy to Tomcat 7, page loading attempt gives
java.lang.ClassNotFoundException: javax.enterprise.context.spi.Contextual
I tried adding dependency for cdi-api. ClassNotFoundException goes away but then I get javax.naming.NameNotFoundException: Name [BeanManager] is not bound in this Context. Unable to find [BeanManager].
I have the same problem with my own Vaadin 7 application using cdiutils. Any help would be appreciated.
ask：
Tomcat doesn't provide a CDI container per se. Surely you can include one manually but it's easier just to deploy to a Java EE compatible web app server such as TomEE: http://tomee.apache.org/apache-tomee.html
