Hello Dmitry
Thank you very much for your reply.
Unfortunately it didn’t solve my problem. I think it is because I want to access the
EntityManager of the Keycloak persistence unit itself. This persistence unit is defined in
the keycloak-model-jpa JAR referenced by the module "org.keycloak.keycloak-model-jpa”
and it is named “keycloak-default”. I can not access it, because it is not exposed via
JNDI (e.g. with <property name="jboss.entity.manager.jndi.name"
value="java:/yourEntityManagerName"/>).
We use the Keycloak SPI
org.keycloak.connections.jpa.entityprovider.JpaEntityProviderFactory to persist our own
JPA entities.
More precisely my question is the following: is there a way to get access to the Keycloak
EntityManager in a MDB or EJB within a custom deployment?
Best regards,
Edwin

Hello Edwin,
Keycloak does support stateful EJBs as extensions:
https://www.keycloak.org/docs/latest/server_development/index.html#levera...
These EJBs are able to obtain an EntityManager as follows, without specifying unitName:
@PersistenceContext
protected EntityManager em;
Could you try the same in your MDB? If that doesn't work, I think you could create a
dummy stateful EJB whose sole purpose would be to propagate EntityManager, KeycloakSession
etc. to your MDB (via e.g. JNDI).
Good luck!
