We'll publish an example of how to do this soon, but I'd recommend writing
an API based provider on your legacy system instead of using a direct
database connection from Keycloak. Sorry, doesn't exactly answer your
question but it's a more elegant solution.

I'm developing a keycloak user-federation-provider and i need to

it with the JPA persistence system in order to write on my legacy db and on
the keycloak db.
I read that Jboss WildFly already uses Hiberante 4.3 JPA, so i choose to
follow this line for my project.
Another requirement is to decouple the provider and the JPA
model-mapping-project, so my JPA model-mapping-project has to be deployed
a separated jar file.
Following the keycloak userguide i deploy the provider simply coping the
built jar project into the .../standalone/configuration/providers directory.
The JPA model-mapping-project jar file is deployed into the Wildfly using
the management console deployment section.
Now i'm facing up to 2 problems:
1) the user-federation-provider doesn't see the model-mapping-project
classes (throwing the ClassNotFoundException)
2) if i simply copy the model-mapping-project.jar into the
/standalone/configuration/providers directory, the fereration provider sees
the classes but the EntityManager dependency injection does not work
(NullPointerException)
What the way i can solve this problem?
Is there another way to deploy providers? and what about the jar and the
depecency injection?
Thanks
Regards.
