I’ve created a simple project so that I can experiment with AxonFramework running in a Java EE 7 environment, but when I try to deploy the EAR file to the application server, the deployment fails with the error message “Could not resolve a persistence unit corresponding to the persistence-context-ref-name [org.axonframework.common.jpa.ContainerManagedEntityManagerProvider/entityManager] in the scope of the module called [cqrsdemo-ear#cqrsdemo-web-0.0.1-SNAPSHOT.war]”.
The project is comprised of an EAR module which contains an EJB module and WAR module. The EJB module is basically an adaptation of the “To Do Item” quick start tutorial, but without the test fixtures and instead the ToDoItemCreatedEvent and ToDoItemCompletedEvent events invoke the JPA entity manager to insert/update records into an Oracle database. Within the EAR module is a singleton class that is invoked on startup to initialize the AxonFramework (i.e. command bus, command gateway, event bus, event respository, etc). The WAR module is a very simple JSF web based application that calls a the singleton class in the EJB module and invokes the CreateToDoItemCommand and MarkCompletedCommand commands.
What I don’t understand is why AxonFramework is causing this error to be thrown given that the war module referenced in the error message does not use JPA.
Is anyone able to suggest where I might be going wrong or give me some pointers to resolve this issue please?
The full error from the server log file is as follows:
