EJB as a controller

When developing a Java EE application, can I use EJBs as controllers?

An EJB container provides features such as lifecycle management and concurrency management. Is it right to create a standalone EJB for management and inject it into a ManagedBean?

From EJB 3.0 and especially in 3.1 EJB Beans, there are more and more POJOs, which is why the EJB concept is eroded in favor of a more general managed Bean concept within CDI. Even the annotation @EJB“competes” with @Injectand can eventually be replaced by it.

Thus, in a CDI, a controller can be a Bean and use Java EE server features such as lifecycle management, etc.
