Enterprise Java Beans (EJB) Sample

This sample demonstrates injection of an EJB into a servlet. The application consists of a servlet and stateless session bean. The servlet uses annotations to inject the stateless session bean, and then performs a call on the hello method of the bean.

This sample can be installed onto runtime versions and later.
