[keycloak-user] ClassNotFoundException: Custom UserStorageProvider
Hello,
I've implemented a custom User Storage Provider to connect to a
configurable (external) database through Hibernate/JDBC:
public class MyUserStorageProviderFactory implements
UserStorageProviderFactory<MyUserStorageProvider> {
// ...
public MyUserStorageProvider create(KeycloakSession session,
ComponentModel model) {
logger.info(">>>>>> Creating factory");
PersistenceConfig config = new
PersistenceConfig(model.getConfig());
entityManagerFactory = new
HibernatePersistenceProvider().createContainerEntityManagerFactory(getPersistenceUnitInfo(),
config.asProperties());
entityManager = entityManagerFactory.createEntityManager();
return new MyUserStorageProvider(entityManager, session, model);
}
// ...
}
In src/main/resources/META-INF I've placed a file named
jboss-deployment-structure.xml:
<?xml version="1.0" ?>
<jboss-deployment-structure>
<deployment>
<dependencies>
<module name="org.hibernate" />
<module name="org.jboss.logging" />
<module name="org.keycloak.keycloak-core" />
<module name="org.keycloak.keycloak-server-spi" />
<module name="org.postgresql" />
</dependencies>
</deployment>
</jboss-deployment-structure>
Although there's a dependency for org.postgresql I'm getting a
ClassNotFoundException when trying to authenticate:
WARN [org.keycloak.services] (default task-6) KC-SERVICES0013: Failed

PostgreSQL is deployed as module as described here:
