Yes. But the term container is a bit fuzzy. A HashMap is one, too.

According to the spec:

This specification defines the responsibilities of:

• the application developer who uses these services, and


• the vendor who implements the functionality defined by this specification and provides a runtime environment in which the application executes.

This runtime environment is called the container. For example, the container might be a Java EE container or an embeddable EJB container.

Or it might be something else - just as long as it implements CDI.
