At the moment when the provider is specified in keycloak-server.json we
only load that one provider. If you only need to use the
EntityManagerFactory within your user federation provider you don't need a
JpaConnectionProvider at all. Just create the EntityManagerFactory within
your UserFederationProviderFactory. We only use the JpaConnectionProvider
as we have multiple providers using the same EntityManagerFactory.

Hello
I am trying to implement a userfederation-provider based on a
jpa-connection. My approach was:
According to an additional datasource-defintion for the federated DB in
the standalone.xml
<datasource jta="true" jndi-name="
*java:jboss/datasources/CCPDS*" pool-name="CCPDS"
enabled="true"
use-ccm="true">
<connection-url>jdbc:oracle:thin:@servername
:1521:schemaname</connection-url>
..
, I tried to register this datasource as an additional connectionJpa-entry
in keycloak-server.json as follows:
..
"connectionsJpa": {
"default": {
"dataSource": "java:jboss/datasources/CCPKCDS",
"databaseSchema": "update"
}*,*
* "**FED**-**DB**": {*
* "dataSource": "java:jboss/datasources/CCPDS"*
* }*
},
..
According to these configuration I hoped to be able to establish the
appropriate entity manager by coding:
// Get the appropriate entity manager from the KeycloakSession
EntityManager em = session.getProvider(JpaConnectionProvider.
*class*, "*FED**-**DB*").getEntityManager();
This did not work, indeed there is still only one (default)
JpaConnectionProvider available in the session (JpaConnectionProviderList
size is 1):
Set<JpaConnectionProvider> *JpaConnectionProviderList* = session
.getAllProviders(JpaConnectionProvider.*class*);
My question is: isn’t it in principle possible to register a second
jpaConnector additionally to the default one or is there something missing
or wrong in my approach?
Thanks for any help in advance.
Best regards, Eduard Matuszak
