As I explained in “Inject Java EE Beans into Tapestry-5.x“, the AppModule offers a way to configure Tapestry Web Applications directly in Java. In that post, we injected Java EE Beans into Tapestry applications. This time we do the same with Context and Dependency Injection (CDI) Beans. It follows the same procedure. The only difference is the way of looking up a bean. We still use JNDI for a lookup, but this time we retrieve the CDI BeanManager. In a second step we get the bean. For performance reasons we retrieve the bean only once per Thread (see annotation @Scope). It will be cached for subsequent lookups.
