The problem was solved by following this approach: Changes in components.xml | <core:init debug="@debug@" jndi-pattern="@jndiPattern@" transaction-management-enabled="false" /> | | <transaction:ejb-transaction/> | Now I can use the @PersistentContext from within the application, but what if I want to use the entity manager because I would like to reduce the amount of usage of EJBs. Ideally I would want to inject the entity manager such as: | @In ("entityManager") | EntityManager em; | Any hints on this?
