[keycloak-user] Providers with CDI

[Alexander Chriztopher]

thank you Stian.

I have found my error. I was using a JTA transaction provider and changed
that to a local one and it is now working.

Just in case anyone is interested this is how my persistence.xml is :

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="security" transaction-type="RESOURCE_LOCAL">
<jta-data-source>java:jboss/datasources/security</jta-data-source>
<properties>
<property name="hibernate.hbm2ddl.auto" value="validate" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.format_sql" value="true" />
            <!-- Set jboss.as.jpa.managed to false to disable container
managed JPA access to the persistence unit -->
            <property name="jboss.as.jpa.managed" value="false"/>
</properties>
</persistence-unit>
</persistence>

And this how i create my entity manager to handle the transaction :

EntityManagerFactory emf =
Persistence.createEntityManagerFactory("security");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
// some code to save data to the db
em.getTransaction().commit();
