Hi, It looks like you're trying to do Application-Managed JPA rather than container-managed JPA with this example (i.e. you want to have an EntityManagerFactory and manage the EntityManager lifecycle yourself).
In this case you can just inject the persistence unit directly into the bean that wants it with e.g. <bean id="persistenceBean" class="org.apache.Foo"> <jpa:unit unitname="camel" property="enitityManagerFactory"/> </bean> This encompasses all of the integration with global transactions as well as the JPA injection via the setEntityManagerFactory method. Managed transactions can be configured using the transactions namespace e.g. <bean id="transacted" class="org.apache.Bar"> <tx:transaction/> </bean> This bean will have a "Required" transaction attribute for all public methods invoked from outside the bean. These two concepts are often used together with container-managed persistence contexts (i.e you let the container manage the EntityManager lifecycle). There are examples of this in the Blog sample. <bean id="persistenceBean" class="org.apache.Foo"> <tx:transaction/> <jpa:context unitname="camel" property="enitityManager"/> </bean> I hope this helps. If you'd like to put any of your experiences together it would be great to start building some better documentation for the Aries JPA component.
